Hi, Annabelle.

I would suggest you start by reading not just this post, but each of the pages I referred to in it, which contain a lot more details.

Then, if there are specific formulas you struggle with, you might write back and tell me about them, so we can discuss those. Or you might use the Ask a Question link to write to us privately if it will take a longer discussion.

]]>There are circles, triangles, rectangles, cylinders, prisms, squares, and so on.

These all have different formulas. PLEASE is there any way I can remember them?

Appreciate a reply

Thanks heaps

See the series of comments on June 9. The quick answer is, yes, you can, but there is no guarantee that the numbers you get are actual modes. (In fact, the same can *always* be said, since the formula is only an estimate.) The more a distribution deviates from normal, the less meaningful the formula becomes.
