[Solved] MATH225N Week 8 Discussion: Correlation and Regression

Initial Post Instructions

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?

Week 8 Discussion: Correlation and Regression

Holmes,Illowsky,& Dean (2018) define regression analysis as a statistical tool that one can use in testing a hypothesis of correlation. That is, it can be used to measure if a given variable is dependent on one or more independent variables. Additionally, it can be used to predict the magnitude of an effect resulting from a change in one of the variables (Holmes, Illowsky, & Dean, 2018). This particular feature makes regression analysis particularly effective in making predictions.…………….please follow the link below to purchase the solution at $5
