Hello,
I ran a 2x2x2 repeated measures ANOVA which turned out fine:
Df Sum Sq Mean Sq F
value Pr(>F) Attend 1 0.5540
0.55402 7.0374 0.01079 *PercGrp 1
0.0058 0.00580 0.0737 0.78719 Pres 1
0.1794 0.17944 2.2794 0.13766 Attend:PercGrp
1 0.0017 0.00172 0.0218 0.88324 Attend:Pres
1 0.0189 0.01894 0.2406 0.62598
PercGrp:Pres 1 0.0534 0.05344 0.6789
0.41405 Attend:PercGrp:Pres 1 0.0046 0.00464 0.0590
0.80912 Residuals 48 3.7788 0.07872
However, when I run the interactions alone (from the same dataset), I get a
different set of results than what was originally shown e.g.
> anova(lm(main~Attend+PercGrp+Pres))Analysis of Variance Table
Response: main Df Sum Sq Mean Sq F value
Pr(>F) Attend 1 0.5540 0.55402 7.4682 0.008561
**PercGrp 1 0.0058 0.00580 0.0782 0.780849 Pres
1 0.1794 0.17944 2.4189 0.125942 Residuals 52 3.8575
0.07418
I also get different results when i run the interactions alone too. Curious to
know why this is.
Thanks,Jon
