Descriptive statistics provide simple summaries of (large amounts of) information (or data). These summaries are quantitative (e.g. means, correlations) or displayed visually (in graphs, scatterplots, etc.).
Descriptive statistics can be “univariate” (involving one variable), “bivariate” (comparing two variables to determine whether there are any relationships between them), or “multivariate” (analysing whether there are relationships between more than two variables). For multivariate descriptions, the effect of one factor or variable is isolated from others to avoid distorting conclusions.
