Other's On-Line Resources (Chapter 11)

 

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:
    1. Click on the colored title of this on-line resource: "One-Way ANOVA (a)."
    2. After clicking on "Begin," go to the pull-down window called "Choose Dataset" and examine the one-way ANOVA results for each preexisting dataset.
    3. 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:
    1. Click on the colored title of this on-line resource: "One-Way ANOVA (b)."
    2. In the next screen, substitute 5 for the word "undefined" and then click "OK."
    3. On the next screen that pops up, scroll down (past the "Inport/Export Boxes") until you get to the "Data Entry Cells."
    4. 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.
    5. After you've entered your data, click on the "calculate" button.
    6. 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)?
