DEVSQ is a function in Google Sheets that calculates the sum of the squares of the values in a given range. This function is especially useful for calculating the variance and standard deviation of a data set. To use the DEVSQ function, enter the following into a cell in your spreadsheet:
=DEVSQ(range)
Where "range" is the range of cells containing the values you want to calculate the sum of the squares of.
The syntax of the DEVSQ function in Google Sheets is as follows:
=DEVSQ(array)
Where "array" is the range of cells that you would like to calculate the sum of squares for.
The DEVSQ function in Google Sheets calculates the sum of the squares of the values in a given range. This can be useful for calculating the variance or standard deviation of a data set. For example, the following formula calculates the standard deviation of the values in the range A1:A10: =DEVSQ(A1:A10)
There are a few occasions when you should not use the DEVSQ function in Google Sheets. One is when you want to calculate the sum of squares of a series of numbers that are not consecutive. In this case, you can use the SUM function with the INT function to get the sum of the squares of the numbers in the series. Another time you should not use DEVSQ is when you want to find the square root of a number. In this case, you can use the SQRT function.
