Document Summary
Does not deal with causes or relationships. The major purpose of univariate analysis is to describe mean, median, . A research physician might determine the systolic blood pressure, diastolic blood pressure, and pulse for each patient participating. We then examine whether there is a relationship between these two variables. The response variable is the focus of a question in a study or experiment and it is the outcome of the study y . Used to explain/account for the variation in the values of the response variable x . A more common type of factor is some kind of treatment: a specific experimental condition defined at multiple levels. Shows the relationship between two quantitative variables measured on the same individuals. Each individual in the data appears as a point in the plot fixed by the values of both variables for that individual.
