Measures of association are a type of descriptive statistic used in order to find any variables that are related to each other. The associations created by chance among variables tend to decrease in a larger sample size. There are three components to measures of association; the direction of the association, the strength of the association, and the statistical significance of the association. Depending on what is being measured it is important to choose the correct method for determining associations. For example, if one is looking only at nominal variables, then it would be best to use the lambda method for detecting association. Some other tests for measures of association are Somer’s D test, Cramer’s V test, Phi test, and the Gamma test. A regression analysis determines how strong an association is among a single dependent variable and independent variables. It also used to explain any differences that are seen in the dependent variables by using information from the independent variables. ("Regression example: descriptive analysis"). Typically, when running any type of regression analysis, there are a few factors that are taken of special interest. These include the strength and direction of the associations (inverse or positive relationship), which independent variables are actually important for influencing the dependent variable, and, with given independent variables, being able to predict a set of values for the dependent variable. When running a regression
