Document Summary
Bicariate analysis: an analysis that looks at any type of relationship between two variables. There are two variables: the response variables and the explanatory variable. Response variable: the one in which comparisons are made. Explanatory variable: defines the two groups being compared. Statistical methods analyze how the outcome on the response variable depends on or is explained by the value of the explanatory variable. Independent samples: the observation in one sample is independent of those in the other sample. For example, randomized experiments that randomly allocate subjects to two treatment; and an observational study that separates subject into two groups per some characteristic such as gender. Dependent samples: result when the data are matched pairs each subject in one sample is matched with a subject in the other sample. Examples include: a set of married couples, the men being in one sample and the woman in another; and the same person takes part in each of two experimental treatments.
