Texas A&M University Kingsville Correlation and Regression Discussion
Let's discuss the difference between positive association and negative association when describing the relationship between two variables. What do we mean by the least-square criterion? Give a general description of how the least-square criterion is involve in the construction of the least-square line. Why do we say the least-squares line is the “best-fitting” line for the data set?
Use the Internet and find a magazine or journal article in your field of major interest wherein the content of this chapter (Correlation and Regression – chapter 6) could be applied. List the variables used, method of data collection, and the general type of information and conclusion drawn.

Grossmont College David Merrell Rats Used for Treatment Groups Discussion
Context
A high school student named David Merrell did an experiment to examine if music affects the ability of rats to run a maze. The explanatory variable was exposure to music. He had three treatment groups: one group listened to heavy metal music by the group Anthrax. A second group listened to Mozart. The third group never heard music. This last group is the control group.
The response variable was the average time (in seconds) to complete three runs. Every week the rats ran the maze three times. Merrell recorded each rat's average time for the week.
Direct controls of potential confounding variables:
Merrell trained all of the rats to run the same maze.
He gave all mice the same amount of food and light.
All mice had the same approximate age and weights.
During the treatment phase, the rats were exposed to the treatment for the same amount of time, e.g. rats heard music at 70 decibels for 10 hours a day for a month.
Results:
By the end of the month the Anthrax group was much slower at running the maze. The Mozart group was much faster. The dotplots below show average run times for the first and last week of the experiment. Each dot represents one rat. The X-value is the rat’s average run time for the week. (Each rat ran the maze 3 times each week.) The blue line is the mean run time for each treatment group.
If you are curious, here is a video of Merrell explaining his experiment.

Prompt
Merrell claims that he randomly assigned rats to treatment groups. Does the data shown in the dotplots above support his claim? Why or why not?
