Median: statistical term, which refers to arranging the variable values in a statistical population in order of size to form a sequence. The variable value in the middle of the variable sequence is called the median, which is expressed by me. When the number of terms n of the variable value is odd, the variable value in the middle position is median; When n is an even number, the median is the average value of the two variables in the middle.

Mode: statistical term, the numerical value with obvious concentration of trend points in statistical distribution, which represents the approximate level of data (mode may not exist or there may be more than one). Revision definition: it is the value with the highest frequency in a set of data, which is called the mode. Sometimes there are several patterns in a set of numbers. Represented by M. rational knowledge: in short, it is the number with the largest proportion in a set of data.

For example:

For example, a set of data 1, 1, 3, 4, 5.

The median is 3 and the mode is 1.

Another example is 1, 2, 2, 2, 3, 4, 5.

The median is 1.5, and the mode is 2.
