Average is an important concept in statistics. The average in primary school mathematics generally refers to the arithmetic average, that is, the quotient obtained by dividing the sum of a set of data by the number of this set of data. In statistics, arithmetic mean is often used to represent the overall level of statistical objects, and it is a statistic that describes the position in the data set.
It can be used not only to reflect the general situation and average level of a group of data, but also to compare the data of different groups and see the differences between groups. It is intuitive and concise to represent a set of data by average, so it is often used in daily life, such as average speed, average height, average yield, average score and so on.
