# Statistics effect of different operational definition for relaxation

**Question description**

Suppose we wanted to see what effect a different operational definition for relaxation during studying would have. Instead of using a dimly lit room, the scent of lavender, and soft music, suppose we had students select their own light level, scent, and music in which to study, encouraging them to help whatever would help them to relax. We then measured the number of errors, each student in this condition made on a recall of material learned under these conditions, and obtained the following errors for 50 students: 5, 2, 2, 1, 0, 4, 2, 1, 1, 0, 3, 3, 0, 0, 0, 1, 0, 2, 1, 7, 5, 0, 2, 4, 0, 5, 3, 6, 0, 1, 3, 5, 3, 6, 0, 1, 3, 5, 2, 4, 2, 0, 5, 1, 3, 6, 4, 1, 0, 3, 4, 2, 0, 1, 3, 6

1) place the data in an array

2) Group the data and place the results in both a table and a histogram and discuss the results (shape of the distribution. Etc.)

3) calculate the mean, median, mode, and standard deviation

4) discuss your results in #3 (describe the distribution, choose the best measure of central tendency, etc.)
