Question about contrast coefficients in split plot ANOVA

[petervenkmanjr]

I had a statistical question regarding specific contrasts for a mixed ANOVA that I am running (Cond is a between subjects factor and Time is a within subjects factor). I hypothesized a very specific pattern of the data, which you can see below, and was trying to figure out if there was a way to test for this pattern using contrast coefficients. I’m sure there is, but I’m a little lost and thought someone might be able to help out.

This is the pattern I’m hypothesizing for my measure of the dependent variable across time and by condition.




I was planning on testing it in phases as this relates to specific processes related to my design.

The firs pattern I need to test is for Times 1 through 4. Because this represents a modified “magic cell” interaction I created the following contrasts for these time points.



The second pattern I need to test is for Times 4 and 5. I created the following contrasts for these time points.



The last pattern I need to test is for Times 4 and 6. This is just a replication of the second pattern.



Will these work as my contrast coefficients? Thanks for you help.
