Carrie Batmen, Thor Church, Tiffany Kavanaugh, Jennifer McCosh, Toni Cerna, and Erica Cozad

Sampling Method: Systematic Sampling•Initially sampled 3rd student, then•Sampled every 4th student until sample size was met.•Sample size of 100 “traditional” SLCC students.

STUDY DESIGN

Survey Questions1. Are you taking classes on campus at SLCC?2. Are you taking at least 12 credit hours?3. How old are you?4. How many hours a week do you study?

Who were our sample subjects:•matriculated ”traditional” SLCC students

―taking at least 12 credit hours―with at least 1 on campus class

•campuses of student sampling: ―Redwood ―South City

― South Jordan ―Sandy

From all of the statistical data, the two variables; age and hours of homework per week; have no linear correlation. This is determined by the way that the graphs are shaped and the relationship of the two data points on the scatterplot.

The linear correlation coefficient r=0.0042 means that the closer the number is to zero the two data points have no linear correlation.
