| For a scatterplot | For a barchart |
|---|---|
| Choose x and y | Same! |
| Label x, y, and give a title | Same! (except x usually has no units) |
| Decide minimum and maximum values for x and y | Only for y -- and include the error bars |
| Decide distance for ticks | Only for y |
| Make a legend | Same |
| Add data, using dots | Use rectangles, not dots |
Choosing between SD and SE

| Quantifies the population | Quantifies your experiment |
| Does NOT depend on sample size | DOES depend on sample size (a lot!) |
| Use to characterize the population | Use to test your results |
If you want a printer-friendly version of this module, you can find it here in a Microsoft Word document. This printer-friendly version should be used only to review, as it does not contain any of the interactive material, and only a skeletal version of problems solved in the module.
