mode

Mode (Mode) refers to the number of times or frequency of occurrence in a group of data, which is a position average and is not affected by extreme variable values. Mode is mainly used to measure the centralized trend of classified data, and it can also be used to measure the centralized trend of sequential data and numerical data. A set of data may have multiple modes, or it may not exist. For quantitative data that are not grouped, we seldom use modes.
