Document Summary
An association claim describes the relationship found between two measured variables. Bivariate correlation (bivariate association) is an association that involves exactly two variables. To investigate associations, researchers need to measure the first variable and then measure the second variable (in the same group of people) Graphs and simple stats are used to describe the relationship between the variables. Categorical variables variables that fall in either one or another category. Can also be represented using a scatterplot (like the one shown ) An association claim is not supported by a statistic or graph, rather its supported by a study design in which both variables are measured. With an association claim, the two most important validities to interrogate are construct validity and statistical validity. Construct validity how well was each variable measured. Association claim describes the relationship between two measured variables so it is important to ask about the construct validity of each variable and how well they were measured.
