GLC Practice 1: Descriptive Statistics and Engineering Graduates

Comparison of Two Sets of Data

1. Load the data into your environment by reading in the CSV file (Engineering_Undergraduates_sample_1000.csv) to the variable engineers

2. We will be focusing on the variables Salary.K., job, and School.

3. First let’s only look at graduates who got a job

4. Now we will focus on the variable Salary.K. compared across the two schools.

5. How do the numeric summaries of the two school’s graduates’ salaries compare to the numeric summaries of the salaries of all graduates computed in step 3a.? Why do those comparisons make sense?
