TIPS FOR SUCCESS

Do each step one at a time. Running statistical tests requires paying attention to details.
Pay special attention to which data file to use—you’ll use several of them.
Keep JASP, your textbook, and Statistical Analysis in JASP: A Guide for Students open when working on your worksheet.
Read, don’t skim, each part of the worksheet. The text will often help you find the answer.
Do the entire worksheet (it’s long).

When you are done, scroll to the very end of the document. Then scroll up slowly to double-check that you have an answer in each box. Going in reverse (from the end to the beginning) is often the best way to spot something you overlooked earlier.
