Which of the following is used to compare the medians from two samples? Predictor variable is often confused with independent variable. A predictor variable is a variable that is being used to predict some other variable or outcome. The units of all regression variables must be the same. Reversing the equation then leads to predictions which ought to be useful. This phenomenon is not unusual at all .' What is the difference between a one-sample and a two-sample chi-square test? For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association.
