One-Way ANOVA (a) |
- Description:
In using this interactive on-line resource, you'll be able to
(1) see one-way ANOVAs performed on different sets of preexisting
data, and (2) generate data of your own that will be analyzed
by a one-way ANOVA.
- What to Do:
- Click on the colored title of this on-line resource: "One-Way
ANOVA (a)."
- After clicking on "Begin," go to the pull-down window called
"Choose Dataset" and examine the one-way ANOVA results for
each preexisting dataset.
- Click "Clear All" and then create your own data by clicking
several times within each group's "data column."
- Sky Huck's Puzzle Question:
It is possible to create a new dataset--with only 3 scores per
group AND each group's mean lower than 1.00--that yields F = 5.06
and p = .05. Can you duplicate this feat?

| One-Way
ANOVA (b) |
- Description:
In using this interactive on-line resource, you'll be able to
generate data of your own that will be analyzed by a one-way ANOVA.
- What to Do:
- Click on the colored title of this on-line resource: "One-Way
ANOVA (b)."
- In the next screen, substitute 5 for the word "undefined"
and then click "OK."
- On the next screen that pops up, scroll down (past the "Inport/Export
Boxes") until you get to the "Data Entry Cells."
- Enter, in the Xa column, any 5 scores to be the data for
the first of your 4 samples. Also enter 5 scores for each
of the other 3 samples.
- After you've entered your data, click on the "calculate"
button.
- Scroll down to the ANOVA Sumarry Table to see what happened
when a one-way ANOVA was applied to your data.
- Sky Huck's Puzzle Question:
Using the whole numbers 1-20 as your data (with each of these
scores used once and only once), how small can you get the ANOVA
F-value to be if you have the freedom to arrange these 20 pieces
of data however you would like (so long as you put 5 scores into
each of the 4 samples)?
