Help? base-factor ANOVA
so i have kids: id,class, grades (math, eng, lit, art, yearly average).
3 classes: (9th, 10th, 11th)
we try to see if there is a Expected value difference between classes.
H1: 1 is diferent
JASP input: (scale-average, c-class)
If I understood this correctly then our BF is 2.798, so It's a bit more likely that we get H0 then rejecting it (=not getting the H1). so basiclly there aint much difference between classes, right?
[at least by E - they get a bit more likelly to get to the PO as they grow)
or did i completly messed it up?
also, can anyone explain to me what the bfm means and why BF 10 is 1 for the null model?
[sorry if my questions are dumb - i learn this program on my own]
