Multivariate statistical analysis involves analyzing more than two variables simultaneously. Examples include multiple regression and discriminant analysis. Univariate data involves one variable, bivariate involves two variables plotted against each other, and multivariable involves three or more variables together. The two main types of multivariable techniques are dimension reduction which simplifies data, and regression which investigates relationships between dependent and independent variables.
