What does it mean when we say a test statistic is conservative? What is a confounding variable? What are the 4 main types or data in statistics? What statistic identifies the value that is greater than or equal to 50% of the other data points in a distribution?
What is a confounding variable? provide an example. If the coefficient of determination between two independent variables is 0.20, what is the VIF? If the independent variables explained less than 50% of the variation of the dependent variable, which of the following would be true? a. The coe...

Confounding by indication is a special kind of confounding; a confounding variable is a special kind of covariate; and a covariate is a special kind of independent variable in regression analysis. These terms and concepts are explained with the help of examples....
We expect that the number of hours a student studies is related to their exam score—i.e., the more you prepare, the higher your score will be. Let’s add the moderator “IQ.” Here, a student’s IQ level can change the effect that the variable “hours of study” has on the exam...
