Subject: Common perceptions about property crime.
I have analyzed the given data on factors that relate to crime rate in the United States.
Data Operations Manager, Louis J. Moritz collected data from 50 states. The data collected was the following:
* Property crime rate per hundred thousand inhabitants.
* Per capita income per state
* High school dropout rate (%, 1987)
* Average precipitation in inches in the major city in each state
* Percentage of public aid recipients
* Density, or population/total square miles
* Public aid for families with children
* Percentage of unemployed workers
* Percentage of residents living in urban areas
* The primary determinants of crime rate in the United States are the high school dropout rate, families with children receiving public aid, and the percentage of residents living in urban areas.
* The model reveals that there is extremely strong evidence that the dropout rate effects the crime rate, the model reveals that there is very strong evidence that density is related to the crime rate, and the model reveals that there is some evidence that public aid effects crime rate.
* For each additional dropout percent increase, there will be an increase of 79.39 in crimes committed in the total population of 100,000.
* For every family offered public aid , there will be a decrease of 124.5 crimes committed in the total population of 100,000.
* With each increase in population per square mile, there is a decrease of 1.84 in crimes committed in the total population of 100,000.
The model is considered strong with a 68% total variation in crime rate is justified in this model. It is very evident that crime rate is effected mostly by the dropout percentage. This model shows that it is 95% confident that in the population each percentage increase in dropout rate will result in an...
