What is the function of descriptive statistics?

The function of descriptive statistics is to summarize and describe the main features of a data set. This branch of statistics provides simple summaries about the sample and the measures. For instance, measures such as mean, median, and mode summarize central tendencies, while measures like range and standard deviation describe variability. Descriptive statistics also include visual representations, such as graphs and charts, which help in understanding data trends at a glance. By providing clear and concise insights, descriptive statistics help researchers communicate their findings effectively.
