one-Way ANOVA

Postby BurnsieUK » Mon Apr 04, 2016 12:57 pm

Hi all.

sorry for the basic question, but I've not done stats for many a year.

So,

I have a group of participants, all of which go through all the tests and intervention (they are not split into any groups, no control group etc.).

Each participant does two different pre-tests and two different posts (intervention) test.

I am wanting to find if there is a sig difference in any test post intervention.

Should I be preforming a one-way ANOVA as x2 t-tests with increase type I errors??

thanks :P

but isn't a repeated measures more than 2 measures on the same variable i.e. heart rate pre, mod and post a 1 mile run?

no you can use it for 2 timepoints only you cant do post-hoc tests. You can do those "manually" though by just running a paired sample t-test with some type of correction (most conservative is taking p=.025 as sig level).

You use the phrase "in any test post intervention;" are you just looking to compare the post-test portion? If so then the ANOVA is fine
