using the normal distribution function on numbers

The functions are the same as in Excel, except for how you reference cells in Numbers vs Excel. There is a ton of Excel help out there and I often search on that instead. One thing to be careful of is that discussions about Excel functions often involve their "array" functions, which look just like regular functions except for the cell referencing where they will put a range (i.e., C2:C20) where there should be a single cell reference (i.e., C2). Avoid those.

If you don't find what you need or it doesn't seem to be working, come on back here. We will need more specifics on what you are trying to do plus things like the specific function you are having a problem with, what you have tried so far, a screenshot of the table/chart, etc. It is nearly impossible and way too time consuming to answer a general question about using every statistical function related to the normal distribution.

I don't know if you looked at the function descriptions while in Numbers. If you type an = into a cell, a window will pop up that has all the available functions. If you click on one of them a description of it will show up at the bottom and usually with a few examples of how to use it. I still recommend reading online about the Excel versions of them, though, because it is more verbose.

Which specific functions are you looking at, and specifically what kind of problem are you trying to solve?
