The objectives of this activity are:

• To teach you how to use to produce side-by-side boxplots and the relevant descriptive statistics,
• To let you practice comparing and contrasting distributions, and

The percentage of each entering Freshman class that graduated on time was recorded for each of six colleges at a major university over a period of several years. (Source: This data is distributed with the software package, Data Desk. (1993). Ithaca, NY: Data Description, Inc., and appears in http://lib.stat.cmu.edu/DASL/)

In order to compare the graduation rates among the different colleges, we will create side-by-side boxplots (graduation rate by college), and supplement the graph with numerical measures. Follow the instructions, and then answer the questions based on the output you got.

## Instructions

Click on the link corresponding to your statistical package to see instructions for completing the activity, and then answer the questions below.

## Question 1:

Compare and contrast the distributions of the graduation rates at the different colleges. Be sure to address center, spread and outliers.

## Question 2:

If you had to choose one college among the six colleges based on this data, which college would it be? Explain your reasoning.

## Question 3:

If you were debating between colleges B and F only, which one would you choose based on this data? Explain your reasoning.
