Visual ANOVA is an interactive Flash program which demonstrates visually how variability between and within experimental groups contributes to the F ratio in the Analysis of Variance. It is not a numerical calculator; rather it visually and holistically demonstrates the relations among important concepts. Visual ANOVA is supported... More

This is a good tool to demonstrate the idea of ANOVA. Easy to understand and follow. I will use the tool to demonstrate ANOVA in class.

Very helpful discussion of one-way ANOVA. Beautiful, colorful applet and accompanying lecture notes. Lots of ways for the students to play with the data. Excellent learning tool. Could be used in lecture on by the students as a tutorial.

Technical Remarks:

The link to online homework didn't work for me using Firefox.
Time spent reviewing site: 15 minutes.

What a great tool! An analysis of Variance (ANOVA) is a
statistical method for making simultaneous comparisons
between two or more means; a statistical method that
yields values that can be tested to determine whether a
significant relation exists between variables.

Well, now that we've got the dictionary definition out
of the way....

An ANOVA gives you an estimate of whether two (or more)
groups are likely to be mathematically related.

One of the favorite tricks of those who deliberately
dissemble is collecting data from two (or more) groups
and presenting results without checking to see if the
groups are in fact are related. More commonly stated:
they compare apples an oranges. ANOVA is *one* method
of determining if the two groups should be related.

This tool allows the results of an anova to be
calculated and displayed visually.

Technical Remarks:

I spent ~ 30 minutes 'tinkering' with the program.

After thirty minutes trying out this program, I found it highly beneficial in
shedding some light on the ANOVA. I had previously found this statistical
concept as dull and uninteresting. However, after the use of Dr. Malloy's tool I
am able to look at this concept in a different way thanks to his online
presentation of the material. Anyone who holds similar feelings as I used to for
the ANOVA should seriously consider the use of Dr. Malloy's interactive tool.
