Descriptive statistics are used to summarize and interpret data by providing meaningful and concise descriptions of the main characteristics and properties of a dataset. These statistics help to organize, analyze, and present data in a way that is easily understandable and allows for meaningful comparisons. Here are some key ways in which descriptive statistics can be used:

The mean is the arithmetic average, the median is the middle value when the data is sorted, and the mode is the most frequently occurring value. These measures provide a central reference point that helps understand the overall trend or center of the data.
