3) What is the mean, median, mode, and standard deviation of each of the groups. You may
use a program (such as excel) to calculate this. 2 or 3 sentences describing the difference
between the groups, focus on spread, outliers, and any other pertinent information.
4) Create a boxplot comparing the two groups, you may use a program to accomplish this.
Spend 2 or 3 sentences describing the two figures and what they show
5) create a histogram of both groups, you may use a program to accomplish this. Describe the
distribution, what does it look like? Please spend 2-3 sentences.
