Tools that need to be prepared: computer, Excel software. 1, first open Excel software. 2. Enter the data source into the excel table. 3. Enter the function = stdev in any empty cell, which will automatically display a function of multiple standard deviations. 4, select the function of STDEV, this function can be compatible with the 2007 and previous versions. 5, left brackets will appear behind the function, you need to enter the data to be calculated.
Select the cell that needs to be placed and value, and then click the automatic and shortcut tool to generate a = SUM formula. At this time, the sum of the sum of the sum is intelligent, but it is not necessarily desired;
Hasing the mouse to select the area again. If there is a non -continuous area, press CTRL, click the unit grid or area to select it; "√", that is, get the sum of sum.
Excel has a function formula "stdev ()", which means standard deviation (that is, Sigma). 3 Siegma can be used as 3. . It can be entered "= 3*STDEV (range range)" in the cell.
