Explanation

A.) Regression and correlation are the most used and most abused tools in research. People are often quick to jump to the conclusion that if a relationship exists between two variables, one must cause the other. In reality, there are many reasons why two variables can be related without causality.

Give a plausible explanation for each of the following correlations:

There is a strong relationship between the number of cops on our streets and the number of reported crimes. Does this mean that cops commit crimes or that criminals are more bold when cops are on the streets? Explain how this correlation is true.
