Highlight the cells you want to use to calculate the median. Although MODE is specified as taking a maximum of 30 arguments Google Sheets supports an arbitrary number of arguments for this function. The median is the central number of a data set.
Click on an empty cell and type MODE into the cell or the formula entry field replacing and with the values or ranges to consider for calculation.
The advantage of using the function is. If the combined value arguments contain an even number of values MEDIAN will interpolate between the two center values. For example the mode of the set of values 1 2 2 3 4 6 is 2. There is no MEAN function in Google Sheets.
