you want the actual distribution? in which case you will need to create a histogram, using count().

If you are assuming a certain distribution e.g. normal, then you need to calculate your Standard Deviation and mean, and then use e.g. normdist() for a spread of numbers

Which do you need?

The frequency command is your friend if you want a histogram.

I'll have a look see if there's an example to hand.

Edited for example:

=Frequency(value range,histogram bin range) then use ctrl,shift,return to make it an array command.

You can put as many bins in the histogram as you want, the frequency command will return all values less than the bin value (and above the previous bin obviously).

Hope this helps

Matt
