micro level using

Cal guine coefficient and lawence curve guine coefficient and lawence curve the

guine coefficient and Lawrence curve are tools used to measure income inequality within a

population

there is always anality in the

income lawence image you lined up everyone in a population from poorest to

the richest poorest

di the LA plot the cumulative percentage of income earned

by fast

forward

the lawence curve plots the cumulative percentage of income earned by the

population against the cumulative percentage of people starting with the p

poorest a perfect inequality situ situation would be diagnosed line where

each percentage of the population earn the same percentage of income guine

coefficient the guine coefficient in a number between 0 and 1 that represents

the area between the perfect equality line and the Lawrence C again coefficient of zero represent perfect

equality everyone has the same income while a coefficient of 1 percentage

perfect inequality 1% has also the income the closer the guine coefficient

is 21 the greater the income inequality

surpr one

LP cating thee short simple sub method arrange the

population in ascending orders of income calculate the lawence Cup by plotting the cumulative percentage of income

received against the cumulative percentage of the population

Cate calculate the area under the Lawrence curve a calculate the areas of perfect in equality triangle B guine

coefficient is a minus B minus a / B in

a bracket so the guine coefficient is a measure of income inequality drive from

the Lawrence curve with zero representing perfect equality and one

percentage perfect inequality guine coefficient short

notes nearest neighbor analysis and occupational tertiary diagram nearest

neighbor analysis nearest neighbor analysis is the method used to study

pattern of spatial distribution image you have a set of points represent for

example trees in a forest these analysis help to determine if these points are

random L distributed or if there is a pattern to their Arrangement how it

works for each point you calculate the distance it nearest neighbor then you

compare this distance to what would expect if the points we are randomly

distributed if the distance are significantly different it suggested a non random

pattern occupation occupational tertiary diagram

an occupational tertiary diagram categorize occupations into three main

groups based on certain C characteristic it helps visualize the distributions of

occupations within a population who how it works number one

identify three characteristic or factors relevant to the occupation you are

studying for example skills level income or industry type number two plot each

occupations on the diagram according to its values for these factors number

three the three corners of the triangle represent extreme values for each

factors number four each occupations Falls somewhere within the triangle

indicating its maximum of characters methods of calculating tertiary

diagram identifying three factors determining the three main characters or

factors you have to analyze for each methods for calculating tertiary

diagram number one identify three factors determine the main three main

characters or factors that want to analyze for each occupations sorry for

the dog barking behind my video just concentrate on my

voice assign values assign values to each occupation for this three factors

for example if one factor is a skill level you might assign a level you might assign a value from 0 to 100 for each

occupation representing low to high skill level plot points on the tertiary

diagram Mark a point for each occupations according to its values for

the three factors interpretation the position of each points within the

triangle IND Ates the mix of characteristic for that occupation

closer to one corner means a higher level for that factor analyze analysis analyze the

distributions of points to identify any patterns or Trends in the occupations

based on the three factors by using this methods you can visualize represent

analyze and analyze the distributions of occupation based on multiple

characteristics helping to understand the compositions of the workforce more

effectively okay the sixth slide is for exponential

growth curve and population projection exponential growth curve describe rapid

growth where the rate of increase is proportional to the current size

characterized by a cve that start slowly and then steeply Rises commonly seen in

population with abundant resources and no limiting factors population

projection estimates further population sizes based

on current growth rates utilizes mathematical models often based on

exponential growth to predict population changes over time factors such as birth

rate rate debt rate and migration consider in projections help government

and organization plan for future resources needs and infrastructure

development next topic is index number and cumulative

curve index number index number Compares changes in variable in variables over

time bying them has ratios or percentage

often used to track changes in price product or economic indicators provides

a standardized way to measure changes and compare different time periods or

group cumulative index curve illustrate the cumulative change in a index over

time plot the cumulative index values Against Time and showing the overall

trends of change useful for visualizing long-term trends as and identifying

periods of growth and decline one unit one is finished now

moving to the second unit quantitative mapping and

interpretation so the first topic we have is main centers of population and

its shift concentration of population about main centers I'm really sorry that I'm reading right now now but it's very

important for you to just fasten up the video and just listen what I saying

because it's a last minute exam video so it's very important for you to listen to The Voice it will help you to memorize

and also read the screen as well main Center of population the main Center of

population is the average geographic location of a population image placing a

DOT on a map for every person in a city or region the main Center would

be where all these dots would balance out if the map we a flat surface it

gives a central point that represent where people are gradually located over

time changes in population distribution migration pattern and urban population

and Urban Development can cause the main culture to shift tracking the movement of the

main centers helps understand how a population geographic distribution changes over time concentration of

population about main centers it refers to how closely people are cluster around

the main centers if most people are close to the main Center it indicates a

high concentration of population in that area if people are more spread out the

concentration around the main Center is lower understanding population

concentration helps with urban planning resources allocation and infrastructure

development number two location quotation zcore zore

zore location quotation location quotation Q lq compares the

concentration of a particular activity such as in industri or occupation in one

area to its concentration in a larger reference area it helps identify the

relative importance of a specific activity within a given regon compared

to its importance at a broader scale allocation quotation greater than one

indicates that the activity is more concentrated in the areas of Interest compared to the reference area while a

quotation less than one suggest less con less concentration zcore the zcore is a

statistically measure that indicates how many standard deviation a data point is

from the mean of a data set it helps determine whether a particular values is

typical or unusual within the data set a a z a z score of zero means the data

point is exactly at the mean while positive scores indicates values above

the mean and negative scores indicates values below the mean Zed scores are

useful for comparing different data sets and identifying outliner or extreme

values number three number three you need two three

you need two three residual mapping crop combination

analysis residual mapping residual ual mapping is a technique used to compare

observe value with predicted values in a data set it helps identifying areas or

data points where there are significant difference between what was expected and

what actually occurred residual are calculated by subtracting the predicted

values from the observed values positive residual indicates values that are

higher than expected while negative residual indicates values that are lower than expected residual mapping is useful

for identifying patterns Trends and anomalies in data and for evaluating the

accuracy of statistical models crop combination analysis crop combination

analysis involve studying the combinations of crop grown in a

particular agricultural area it helps assess the suit ility of different crop

combination for cultivation in a given region factors such as climate soil

conditions water availability and Market demands are considered when analyzing

crop combination the goal is to identify optimal crop combination that maximize

productivity minimize risk and optimize resources use crop combination analysis

is important for agriculture planning crop rotation strategies and

suit sustainability farming practices number

four population potential gravity model accessibility map

distance centrality Matrix and mat

okay now population potential gravity model the population potential based on

the gravity model predicts the interactions between different places

based on factors that population size and distance between them it assumes

that larger population and shorter distances between places lead to Stronger interaction or flow such as

migration communicating or tread the model calculates the potential

interaction between two places as a functions of their population size and

distance between them often using a formula that inversely relates distance

and strength of interaction accessibility map distance

centrality Matrix map so there is one huge mistake which I have done there is

a full form of mat which is multi accessibility tool that's the full form of ma multi accessibility tool

okay and ex an accessibility map illustrate how easily

people or good can access different location based on factors like distance

or centrality it consider various modes of transport and travels time between

location accessibility map helps identifying area with good or poor

access to Services resources or markets distance Matrix

calculate travels distance between location centrality

Matrix matrices identify central location within a network and multi

accessibility tools that is ma combine multiple factors to assess over

accessibility that is the ending of our unit

two let's move on to unit three that is field techniques

OBS method traffic composition flow biodiversity register crop combination

crop composition observation method traffic composition

flow traffic composition flow observation methods involve visually recording the types and

volume of verles or ped is train moving through a particular area such as Road

interaction or highways observation notes observations note the different

type of vehicles car truck bicycle pedest and their numbers often using

tally marks or recording devices number three this method help Transportation

planners and Engineers understanding traffic patterns identifying congestions find and plan

for the infrastructure Improvement and traffic management strategies let me

check if the video is recording or not I'm very bad at this

thing yes the video is being

record and I don't know the screen is being shared or

not I am really

sorry a specific habitat or ecosystem

observers documents the species names abundance distributions and any notable

observations such as nasing Behavior or feeding habits biodiversity registration

helps ecologist or convers

conversationist and land managers monitor changes in biodiversity over

time SS habited health and prioritize conversation efforts

observation method crop combination crop composition observation method involve

documenting the types and distributions of crop grown in a specific agricultural

areas observation records the name of crop being cultivated their extent that

is he hectares or acres and any relevant detail such as planting methods

or crop varieties and crop composition observation assist

agricultural research Farmers policy makers in assessing land

use patterns identifying cropping Trends and making

information decision regarding agricultural practices crop

diversification and food security I'm really

sorry so you need to survey schedule house survey Market survey passenger

survey tourist survey survey schedule household survey a household survey

collects data about the demographic economic and social characteristic of

household it includes the information such as family size income education level

employment status housing

conditions access to basic amenities household uh survey or used by

government researcher and organization for

policym social program and market analysis survey schedule Market survey a

market survey gather data about consumers preferences buying habitats

habits and market trends it investigates factors such as product preferences brand royality

pricing sensitivity and shopping Behavior Market

surveys help businesses understanding their target audiences identifying

Market opportunities and develop effective marketing strategies survey

schedule passenger survey a passenger survey collects data or passenger uses

of transportation service has a bus train Aeroplane it's include the information

such as travel frequency trip purpose destination mode

of transportation satisfaction with the service quality passenger such passenger

service assist Transportation authorities and companies in optimizing Roots improving Services reliability and

enhancing passenger experience such survey tourist survey a tourist survey

gather information about tourist preferences prep

pretending pattern and travel behaviors it covers aspects such as travel

destination commodities accom ation choices activities expenditure and satisfaction

level tourist survey helps tourist agencies Hospitality businesses and

destination marketers understands visitor preferences tailor offering and promotes

tourism destinations effectively so the next topic is field

instrument portable weather station aaable and

clinometer if I'm pronouncing it wrong please forgive me field instrument

portable weather station a portable weather station is a device used to

measure various atmospheric conditions such as temperature humidity wind speed

and precipitation it consist of sensors that collect data which is then

displayed on a screen or recorded for later analysis portable weather stations

are are used by metrologist researcher and outdoor Enthusiast for weather for

casting climate monitoring and planning outdoor activity available and a an ebne

level is a handland handheld instrument used to

measure angles of elevations or depression it consist of a sighting tube

with the Bubble Level and a protector scale by aligning the sighting tube with

the object being measured and reading the angles on the scale users can

determine the slope or inclinations of the Terran abne levels are commonly used

in surveying forestry and concentration and constructions to measure slope grid

and angles clinometer clinometer also known as an inclinometer is a device used to measure

angles of inclinations or tilt it typically consist of a protector

or level attached to a housing with the heighted pendulum or digital sensor

clinometers are used to measure the angle of elevation or depression of objects such as trees buildings or slope

the they are commonly used in forestry geology in engineering for slope

stability analyses structural assessment and land

survey land use study at micro level

using cadastral mapping cestal map land use study at micro level using

grial map a land use study at the micro level involves analyzing the type and

distribution of land use in a small localized area cestal maps which

shows property boundaries ownership and land parcel

details are used in has the primary source of information for this study

researchers or planers examine the cestal map to identify different land

uses such ha a r residential commercial industrial agriculture or recreational

recreational areas they may also note any changes or development in land use

over time such as new construction zoning changes or land conversation this

information helps in understanding how land is utilize within the study area

identifying patterns of development and making information decisions about Land

Management urban planning or resource allocation land use studies at the micro

level are important for assessing the suitability of land for various

purpose purposes addressing land use conflicts and promoting sustainability

and guine coefficient guine coefficient measured income inequality in a population lawence curve visually

represents income distribution by plotting cumulative income against the cumulative population nearest neighbor

analyses help identifying patterns of special distribution by measuring the

proximity of points to their nearest neighbors occupational terer diagram

categorize occupations into three main groups based on their characteristic

exponential growth curve defects rapid growth where the rate of growth is

proportional to the current size population projection estimates future

population sizes based on current growth rates in index number Compares changes

in variables over time by experiencing them as ratios or percentage cumulative

index curve illustrate the cumulative changes in a index over

time main Center of population and it shift concentration of population about

main Center main centers of populations calculates the average location of a

population concentration a population about the main Center shows

how densely or sply a population is distributed around

this average Point location quotation measures the concentration of a particular activity in a region compared

to its concentration at a larger scale zcore standardized data to determine how

many standards deviation a value is from the mean residual mapping compares

observed values with predicted values to identify areas of over or

underperformance crop combination analysis assesses the suitability of

different crop for cultivations in a given area population potential based on

the gravity model predicts interaction between places based on population sizes

and distances accessibility map measures how usually people or

good can access different location based on factors like distance or

centrality traffic composition flow observe the type and volumes of the

traffic passing through an area biodiversity registration records the

variety of of species in a specific habitat crop compositions observe the

type type and distributions of crop in an agricultural areas household survey

collects data or demographic economic and social characteristic of household

Market Services consumers preferences buying habited and

market trends passenger survey records data or passenger using various modes of

transportation tourist survey gather information on tourist preference is spending patterns and travel

behaviors portable weather stations measures weather parameters like

temperature humidity and wind speed abne level measures angles of elevation and

depression clinometer measures slope angles and the last one is land use

study examines how land is utilized in a specific areas based on a c Cal mapping

cestal map showing property boundaries and land

ownership so that is

all so that is

all so all the best for your exam and see you in the next

video she see you in the next video all the best
