Univariate analysis is concerned with the description or summarization of individual variables in a given data set. Univariate analysis is the first step of data analysis once a data set is ready. Univariate Analysis provides a convenient way to produce the most useful statistics.

Where a researcher wants to report the data on one variable, univariate analysis is used. A researcher may also perform univariate analysis so as to facilitate more complicated analyses, like bivariate and regression. There are graphical and numerical methods for conducting univariate analysis.

In univariate analysis we explore each variable separately in a data set. To present the information in a more organized format, start with univariate descriptive statistics for each variable. Univariate analysis looks at the range of values, as well as the central tendency of the values.

Univariate Analysis describes the pattern of response to the variable and describes each variable on its own. Univariate descriptive statistics can summarize large quantities of numerical data and reveal patterns in the raw data.

Multivariate analysis is a form of quantitative analysis which examines three or more variables at the same time, in order to understand the relationships among them.

Univariate analysis is a form of quantitative analysis of data where each variable is analyzed in isolation.

The simplest form of multivariate analysis is one in which the researcher, interested in the relationship between an independent variable and a dependent variable (eg: gender and political attitudes), introduces an extraneous variable (eg: age) to ensure that a correlation between the two main variables is not spurious.

Univariate analysis can be used when analyzing variation in a data set in which there is only a single variable parameter of interest.
