Continue by selecting the Home tab from the tab ribbon. First select a cell to insert a function into.

SQRT function returns the square root of a number To calculate the standard deviation, you dont need to know the formula. If you are using python 3.4+ there is a standard library module for statistics which will do mean and standard deviation.

STDEV.S function returns the standard deviation of a sample.

We can calculate the standard error of mean by using the functions STDEV.S, SQRT and COUNT. There is no built-in function that directly computes for the standard error of mean. Its formula is the quotient of standard deviation and the square root of sample size. SEM is not as popular as standard deviation, and it is sometimes just referred to as “standard error”. Alternatively, we can select a group of an array (group) of cells based on their coordinates. To calculate the above example we can type: AVERAGE(1,3,10,7,4) This will return a value of 5.
