Statistics and statistical methodology as the basis of data analysis are concerned with two basic types of problems:
(1) summarizing, describing, and exploring the data (descriptive statistics) Another important aspect of data analysis is the data, which can be of two different types: qualitative data, and quantitative data. Qualitative data does not contain quantitative information. Qualitative data can be classified into categories. In contrast, quantitative data represent an amount of something. A third distinction can be made according to the number of variables

procedures are summarized as univariate statistics. More than one variable result in multivariate statistics. A special case of multivariate statistics with only two variables is sometimes called bivariate statistics.
