There are a few different ways to find standard deviation on Excel. One way is to use the STDEV function. To do this, you would first type in the range of cells that you want to find the standard deviation for. After that, you would type in the function "STDEV" and then hit enter. Excel will then give you the standard deviation for the data that you input. Another way to find standard deviation on Excel is to use the "SQRT" function. To do this, you would type in the range of cells that you want to find the standard deviation for. After that, you would type in the function "SQRT" and then hit enter. Excel will then give you the square root of the standard deviation for the data that you input.
