- Use online calculators that make doing some advanced statistical analyses
simple. For example,
- if you wanted to calculate effect size from your t test , you could use this
- if you had unequal variances and wanted to do Welch's t test,
you could use this online calculator
with answering the end-of-chapter exercises.
- Use these very short tutorials to review the
basics of significance testing and the
the t test.
- Use the
online t test calculator to do independent t tests and to see the effects of sample size on t values
(for educational use only; for actual research data, use
- Get a better sense of how often Type 1 errors occur, try this quick
- To learn more about Type 2 errors and how sample size affects power, try
this quick simulation.
- If you are confused about the central limit theorem (p. 408), this 10-minute
video from the Khan academy
may help you.
- Get a better understanding of random assignment by going through this
short (it shouldn't take you more than 10 minutes) but useful
- Get some appreciation of how random error could make two groups differ--and
how large sample sizes tend to reduce the degree to which random error will
cause big differences between groups--by playing with this
