4.40 Sloppy Writing about Correlation. Each of the following statements contains a blunder. Explain in each case what is wrong.
1. “There is a high correlation between the gender of an adult and and their political affiliation.”
2. “We found a strong negative correlation (r=−1.09) between the amount of time spent on social media and the number of books read in the last year.”
3. “The correlation between height and weight of the subjects was r=0.63 centimeter per kilogram.”

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
