Choose any two quantitative variables and collect data from a minimum of n=7 people.
- Calculate the Pearson correlation (r).
- Construct the linear equation, (Y =bX +a) for the regression line.
- Test the significance of the correlation and regression line. Specifically, using = .05 for the test, indicate the critical t-values, conduct the necessary calculations for the test statistic (show work whenever possible) and state the conclusions regarding the original hypotheses (RejectH0or Fail to RejectH0).
- Include a scatterplot of the data. This may be computer generated or hand drawn.
- Write up the results as would appear in a published report.
