Descriptive statistics is the discipline of quantitatively describing the main features of a collection of information, or the quantitative description itself.escriptive status provides simple summaries about the sample and about the observations that have been made. Such summaries may be either quantitative, i.e. summary statistics, or visual, i.e. simple-to-understand graphs.
analysis reflects the ability to break information down into parts, understand how these component parts are organized, and then infer how they are put back together again (classification). the learner must examine how each part relates to each other and find the underlying structure.
