The mean, median, and mode are three types of measures of central tendency. The range, variance, and standard deviation are three types of measures of dispersion.
Also asked, what is descriptive analysis of data?
Descriptive statistics are used to describe the basic features of the data in a study. They provide simple summaries about the sample and the measures.
