Example :

The number of customers a shop has is :

January : 3810

February : 2905

March : 4528

April : 3952

May : 4268

June : 3524

July : 3845

August : 2805

September : 4230

October : 4532

November : 3741

December : 3642


Calculate the mean and sample standard deviation of the number of customers.

Get the result with clicking on :

'μ'

mean is :  3815.16

'σ'

sample standard deviation is  : 554.96
