Descriptive Statistics is a branch of statistics that deals with summarizing and organizing data in order to better understand it. It involves the use of graphical and numerical techniques to describe the characteristics of a given data set.
Descriptive statistics is a branch of mathematics that deals with the collection, organization, analysis, and interpretation of data. It is used to describe the characteristics of a given population or sample. Descriptive statistics are used to summarize data, and to make generalizations about the population from which the data was collected.
Descriptive statistics can be used to describe the basic features of a data set in quantitative terms. This includes measures of central tendency (mean, median, and mode) and measures of variability (standard deviation, range, and interquartile range). Descriptive statistics can also be used to describe the relationships between two or more variables. This includes measures of correlation (Pearson’s r, Spearman’s rho, and Kendall’s tau) and measures of association (chi-square and contingency tables).
Descriptive statistics can also be used to describe the distribution of a data set. This includes measures of shape (skewness and kurtosis) and measures of spread (range, variance, and standard deviation). Descriptive statistics can also be used to describe the relationship between two or more variables. This includes measures of correlation (Pearson’s r, Spearman’s rho, and Kendall’s tau) and measures of association (chi-square and contingency tables).

Descriptive statistics can be used to gain a better understanding of the data, and to make informed decisions about the data.
