MATH 225N Week 8 Discussion: Correlation and
Regression
GIVEN THAT:
If a regression analysis was to be completed on body mass index (BMI), what could be an
independent variable in that analysis? Why? If we could, what other independent variables should be
included in the analysis? What statistic(s) would show the value of that regression in understanding
BMI?
Alternatively, find an article that uses regression analysis to study a medical concern. In that study,
what was the dependent variable and what were the independent variable(s)? Further, how would
you use this study to highlight the difference between correlations and causation?
