Geog 370- Quantitative Methods in Geography

Regression Analysis Part 1 Introduction In the first part of the assignment a simple regression analysis is to be performed on data which attempts to relate the percent of kids in an area who receive free lunch, and crime rate in the same area of a town. This seems silly but performing a regression analysis could help make sense of why this data could relate. The questions that will be answered are; Is the news correct that areas where a larger percent of kids receive free lunch there is a higher crime rate, If a new area of the town was identified with 30% free lunch what is the corresponding crime rate, and how confident is this result. Methodology Definitions   Ordinary Least Squares (OLS): Fitting a line through a set of points and squaring the sum of the vertical distances from observed points so the distance from the trend line is minimized. Regression Analysis : Studies the relation between a dependent and Independent variable. Linear ...

Correlation and Spatial Autocorrelation Goal  The goal of this assignment is to utilize different techniques and software to calculate correlations. Excel, SPSS, and ArcMap are used together to produce different ways of analyzing different data sets. Correlation measure the strength of the association of two variables, and also the direction of association. the results of a correlation always fall between -1 and 1. The closer the correlation value falls to 1 or negative 1 the stronger the relation between the values are. If the correlation falls closer to 0 then there is no or little relationship between the variables. if both the x and y variable increase, then there is a positive correlation closer to 1. If x increases and y decreases then the correlation is closer to -1 creating a negative correlation. Part 1: Correlation Section:1 a) The first task a set of data was given showing Distance (ft) and Sound Level (dB) (Figure 1) and a scatter plot in excel w...
