Hi;

If I am right ( what are the chances ) it is self evident. It says add up what is in each bin and you should have the total number.

hmm .. and Who did define that formula?
I can need to know author and its paper. I can't find.
Please help me to know its writer and its paper where he defined the formula.
Thanks

Hi;

Here is how I see it:

If n is the total number of observations, and k is the number of bins, then mi is the number in each bin or frequency.

Can anyone please explain me formula of histogram defined in this wiki link
http://en.wikipedia.org/wiki/Histogram

We say that histogram is the counts of observation in bins.
So Let say if bins are from 0 to 179. then what does mean by mi in the formula?
i think n is the counts of observation.

Kindly, explain it. thanks

Expecting a fast response
Thanks
