Grossmont College Music Effects in The Ability of Rats to Run a Maze Experiment Discussion
ContextA high school student named David Merrell did an experiment to examine if music affects the ability of rats to run a maze. The explanatory variablewas 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.Merrell explaining his experiment (Links to an external site.)

Brandman University Determining Normality Body Data Worksheet
Determining Normality - Download the data set “Body Data” in your preferred technology format (StatCrunch, Statdisk, Excel). Select 3 columns of your choice from the list below. For each of the 3 columns you selected, determine whether the data is normally distributed in two ways: 1. Create a Histogram of the data and determine if it is approximately bell-shaped, and 2. Create a Normal Quantile Plot and determine if the pattern of points is reasonably close to a straight line. After examining these two graphs together, decide whether the data is normally distributed and explain your findings. Paste your graphs using the Insert/Edit Image button (no attachments!)

Do a Linear Project on a basketball 1/4 of a season or a whole season
For this assignment, collect data exhibiting a relatively linear trend, find the line of best fit, plot the data and the line, interpret the slope, and use the linear equation to make a prediction. Also, find r2 (coefficient of determination) and r (correlation coefficient). Discuss your findings. Your topic may be that is related to sports basketball preferable unless a discussion with me for a different idea. Attached are the documents on the project, tips on the project, and a project example
