What do you mean by univariate, bivariate, and multivariate analysis?

Answer»
  • Univariate Analysis: The word uni MEANS only one and variate means variable, so a univariate analysis has only one DEPENDABLE variable. Among the three ANALYSES, this is the simplest as the variables involved are only one.
    Example:  A simple example of univariate data could be height as shown below: 
  • Bivariate Analysis: The word Bi means two and variate mean variables, so a bivariate analysis has two variables. It examines the causes of the two variables and the relationship between them. It is possible that these variables are DEPENDENT on or independent of each other.  
    Example: A simple example of bivariate data could be temperature and ice cream sales in the summer season. 
  • MULTIVARIATE Analysis: In situations where more than two variables are to be analyzed simultaneously, multivariate analysis is necessary. It is similar to bivariate analysis, except that there are more variables involved.
