How can I make bell curve graphs in Numbers. I am trying to make bell curve graphs for a lab on Natural selection. I have tried a lot of setting but i can't seem to find the way to make those graphs. If anybody knows how to do this can you please give a visual and written of every single step in the least complicate form if that is possible. I would really appreciate anybody help on.

Jenni,
Generally a bell shaped curve represents a distribution of a particular parameter or aspect that has both an average and a standard deviation. Do you have data? If so you need to group the data into bins, then plot the count by bin. This is called a histogram.
Perhaps you can explain a little more what you want to do and what you have already tried.
Hello
The simplest would be to use Grapher.
Example is created by Grapher 2.1 under OS X 10.6.8.

Hi Jenni,
As Wayne asked: "Do you have data?"
You will need to "bin" your data into categories before Numbers can produce a histogram and a bell curve.
See this discussion where Jerrold Green1 shows how to use the INDEX and FREQUENCY functions to prepare your data for a histogram.
To move forward from here, we need to have some idea of your data. A screen shot will help. A picture paints a thousand words 🙂.
Regards,
Ian.
