In addition to formulas, another way to conduct mathematical computations in Excel is through functions. Statistical functions apply a mathematical process to a group of cells in a worksheet.
This chapter gives an overview of some very useful statistical functions like: AVERAGE function, AVERAGEIF function, MEDIAN function, SUMIF function, MIN function, MODE function, STEDV function, LARGE function, SMALL function.
To calculate the average of a range of cells, use the AVERAGE function.
To average cells based on one criteria, use the AVERAGEIF function. For example, to calculate the average excluding zeros.
Note: <> means not equal to. The AVERAGEIF function is similar to the SUMIF function.
To find the median (or middle number), use the MEDIAN function.
To find the most frequently occurring number, use the MODE function.
To calculate the standard deviation, use the STEDV function.
Note: standard deviation is a number that tells you how far numbers are from their mean. Learn more about this topic on our page about standard deviation.
To find the minimum value, use the MIN function.
To find the maximum value, use the MAX function.
To find the third largest number, use the following LARGE function.
To find the second smallest number, use the following SMALL function.
Tip: Excel can generate most of these results with the click of a button.
