You read a study in which 55 male participants (aged 55-70 years) were assessed for handgrip strength, and changes in cardiovascular health over a 2-year period. In the statistical analysis section of the paper you note that the researchers used regression analysis as the statistical procedure. The researchers identify the independent variable as handgrip strength, and the dependent variable as change in cardiovascular health. What do you think the research question could be?You read a study in which 55 male participants (aged 55-70 years) were assessed for handgrip strength, and changes in cardiovascular health over a 2-year period. In the statistical analysis section of the paper you note that the researchers used regression analysis as the statistical procedure. The researchers identify the independent variable as handgrip strength, and the dependent variable as change in cardiovascular health. What do you think the research question could be? Select one: a. Does handgrip strength predict changes in cardiovascular health over a 2-year time period? b. What is the relationship between handgrip strength and age? c. What is the difference in cardiovascular health at 0 and 2-year follow up? d. What is the difference in handgrip strength at 0 and 2-year follow up?
