Explain the Correlation Read the statements below and then identify whether it is a positive (+) or negative (-) correlation. Also, identify what variables you used to generate your answer. 1. Janet is a preschool teacher who has noticed a trend amongst her students. When it is naptime, some students take naps and others do not. Janet wonders whether this affects her student's ability to complete classwork after naptime. She records each student's after naptime productivity for one month and finds she is correct. When students do not take naps, they seem unable to complete the projects she assigns to them in the afternoon. Type of Correlation: Variables Evaluated: 2. Every semester since beginning school, Same has taken 4 courses and has never earned lower than a B. This semester, Sam takes 5 courses and feels like he does not have enough time to study.

The Florida Highway Patrol believes that there are more accidents in winter months when it is colder outside.

Sarah's dog Baxter loves digging in the backyard. Initially, when Sarah got home from work every day and found new holes she would get angry and put Baxter in his doggie crate. Recently, Sarah has been working extra long hours at her job and is tired when she comes home. Sometimes, she forgets to check the backyard and, therefore, does not put Baxter in his crate. Baxter keeps digging more and more holes, in fact more holes than before, probably because he is getting less attention from Sarah. Type of Correlation: Variables Evaluated:
