How to get the mean from no. of entries not from the histogram

ROOT
1

Hello,

I am calculating the systematic uncertainty between three shapes and i want to compare the differences in the mean of each histogram … i have been told that i have to get the mean (calculated with hand if possible) from the no. of entries not the histogram , any idea how to do that ?

i need to get the mean of the highest peak at 1.

thanks,

Mai
