Hi,
I copy pasted the values of adjusted_image variable in the excel, and used the below formulas to calculate the value.
=AVERAGE(A1:JW45) % For Mean
=STDEV(A1:JW45) % For Standard deviation
I got the below answer:
Mean = 1.193168433
std = 0.6329027251
I would suggest you to check the calculations for the mean and standard deviation in your Excel spreadsheet to ensure that the formula correctly includes all the values.
