1. Determine the correlation between glucose, triglycerides, TC, LDL & HDL levels.
-
- Insert correlation table.
-
- Which correlation procedure (Pearson or Spearman) did you choose and why?
- Which correlation is the most positive? Is this a weak, moderate, or strong correlation?
- Which correlation is the most negative?
- Write an overall interpretation of the correlation findings that addresses the strength, direction, and significance of the correlations.
- Run a linear regression for total cholesterol with LDL as a predictor.
-
- Is the model significant? How can you tell (provide objective data)?
- What is your dependent variable?
- What percent of TC is explained by LDL?
- Write a regression equation to predict TC based on LDL.
- Use your regression equation to predict my TC if my LDL is 145. (show equation and answer)
- What range of TC do you expect would give you 95% accuracy of prediction for someone with an LDL of 145?
- Insert regression tables to support answers
- Run a linear regression for HDL with both triglycerides and gender as predictors
-
- Is the model significant?
- Which independent variable contributes most to the equation?
- What is the coefficient of determination value?
- What percent of HDL is explained by these 2 variables together?
- Insert regression table to support answers.
- Write a summary statement describing your findings.
