Web. I created a **standard** **deviation** in the "Values" section, but this field does not show up in the calculation field list. Is there a way to create a calculation of this data with a formula to get the **standard** **deviation** or is there a way to use the "Value" that I have already created and add it to the hourly average of this data? (Using Excel 2010). Web. pd.pivot_table(df.round({'ACRES':1}),values = 'ACRES', index = ['SUPER_TYPE','STRATA', 'OS_TYPE'], aggfunc=np.sum, margins = True) Returns: 2nd example: df.groupby(['SUPER_TYPE']).apply(lambda sub_df: sub_df.pivot_table(index=['STRATA', 'OS_TYPE'], values=['ACRES'], margins=True) ) I'm guessing there are a number of ways to go about this.

This is because pandas calculates the sample **standard** **deviation** by default (normalizing by N – 1). To get the population **standard** **deviation**, pass ddof = 0 to the std () function. # get the **standard** **deviation** print(col.std(ddof=0)) Output: 3.8078865529319543 Now we get the same **standard** **deviation** as the above two examples..
