Univariate statistics summarize only one variable at a time. Does personality predict health and well-being? The goal in the latter case is to determine which variables influence or cause the outcome. Put very simply, "multi-modal" refers to a dataset (variable) in which there is more than one mode, whereas "multi-variate" refers to a dataset in which there is more than one variable. But when we say multiple regression, we mean only one dependent variable with a single distribution or variance. Article Chapter 5 provides a description of bivariate and multiple linear regression analysis. PLoS ONE 7, e34861 (2012). Bivariate statistics compare two variables. undertook supervision. Multivariate analysis uses two or more variables and analyzes which, if any, are correlated with a specific outcome. The most common types of analysis are univariate, bivariate and multivariate analysis [10]) [11]. It is particularly effective in minimizing bias if a structured study design is employed.

When we analyze a variable and use descriptive statistics to calculate measures of central tendency such as a mean, a median, and a mode; Likewise, when we estimate the dispersion or variability as variance or standard deviation, we use a univariate analysis . Protoc. If you have confounding between predictors and outcome you need to control for this in the model. Next, the authors describe the assumptions and other model requirements for conducting linear regression analysis.
