What variables affect the difference in crime rates throughout the neighborhoods of a city?

By Anna Burns

Introduction:
This project is a focus on how variables such as population, ethnicity, and income affect crime rates throughout different neighborhoods throughout a city. I feel that this information finding this information could be useful to many people. For example if you are looking to buy a new home or even start a new business, you’ll probably want it located in a safe neighborhood. This study will help identify the signs of a safe neighborhood.

With white being the predominate race, the graph is slightly left skewed. When I test to see if ethnicity has an effect on crime rates, I will test Hispanic/Latino, Black/African American, and Asian ethnicities.

Estimation:
The first test I will perform is Chi-Square test of independence to compare my categorical data I have against above and below median crime rates. I will be testing above and below averages for population, income, percent white, percent black/African American, percent Hispanic/Latino, percent Asian. I will also be testing direction.
H0: There is no association between the row variable and the column variable.
H1: There is an association between the row variable and the column variable.
H0: There is no association between the row variable and the column variable.
H1: There is an association between the row variable and the column variable.

To test the null hypothesis, if the P-Value of the test is less than 0.05 I will reject the null hypothesis.
