How to ignore certain values in A histogram?

Say I have an grey scale image S and I'm looking to ignore all values above 250, how do I do it with out using NaN? the reason I don't want to use NaN is because Im looking to take statistical information from the resultant image such as average etc.

You can get statistics with NaNs using nanmean or mean(A(isfinite(A(:)))).
