## Excel DEVSQ function

The DEVSQ function calculates the sum of squares of the deviations from the sample mean. #### Syntax

DEVSQ(number1, [number2], ...)

#### Arguments

• Number1 (required): The first number or reference used in the calculation;
• Number2,... (optional): The second and more numbers or references used in the calculation.

#### Remarks

1. There can be up to 255 arguments at a time;
2. Arguments can be:
-- Numbers;
-- Range names, arrays or references that contain numbers.
3. Logical values and text representations of numbers that you directly type in the arguments will be included in the calculation:
-- Logical values: TRUE (1) or FALSE (0);
-- Text representations of numbers: numbers enclosed in double quotation marks such as “2”.
The formula below:
=DEVSQ(1,"2",TRUE,10,8) //The result is 73.2
can be seen as:
=DEVSQ(1,2,1,10,8) //The result is 73.2
4. If the reference or array contains logical values, text, or empty cells, they will be ignored;
5. Cells with zero values will be included in the calculation as well;
6. The #NUM! error occurs when all supplied arguments are nonnumeric;
7. The #VALUE! error occurs if any of the supplied arguments you typed directly in the function are text strings that cannot be interpreted as numbers by Excel;
8. The equation for the DEVSQ function is: Where is the average of the set of values.

#### Return value

It returns a numeric value.

#### Example

As shown in the screenshot below, there is a list of weights in the range B6:B13. To calculate the sum of squared deviations from their mean, you can apply the DEVSQ function as follows to get it done. Select a cell (E7 in this case), copy or enter the formula below and press Enter to get the result.

=DEVSQ(B6:B13) Notes: Arguments in the formula above are supplied as a cell range. However, you can change the formula as follows:

1. Directly type numbers as arguments:

=DEVSQ(50,36,45,72,44,60,55,80)

=DEVSQ({50;36;45;72;44;60;55;80})

2. Reference to each cell in the range:

=DEVSQ(B6,B7,B8,B9,B10,B11,B12,B13)

3. If you have created a name for the range, just reference the range name in the formula (supposing the name of the range is Weight):

=DEVSQ(Weight)
