Applied Data Example 1 (Questions 6 – 12): Correlation and Linear Regression  These data were simulated based on variables in the NHANES dataset. From NHANES: The National Health and Nutrition Examination Survey (NHANES) collects data about the health of adults and children in the United States. We also collect data about what participants eat, drink, and take as supplements to determine how many nutrients are in their diet. These dietary interviews and blood tests help us measure the nutritional status of U.S. adults and children. Research Question and Primary Variables It is hypothesized that individuals with higher levels of adiposity (measured as waist circumference in centimeters) are more likely to have higher levels of fasting glucose (a measure of diabetes risk). Researchers hypothesize there is a positive linear relation between waist circumference and fasting glucose (lbdglusi, a measure of diabetes risk). Mean-centered independent variable = waistcmcent Outcome variable = lbdglusi

What is your conclusion about the mean differences across the treatment and placebo groups?

State the null hypothesis of the ANOVA F-test.

ANOVA output

In simple linear regression, the intercept is the conditional mean of the outcome variable (Y) when the independent variable (X) equals zero. What transformation can we do to the independent variable to ensure the regression model intercept is interpretable?
