Hi,

I have 6 groups of grade data, scored by 6 different graders. I want to know if there are statistically significant differences between graders. Each score was earned by a different student. There were 72 students in all. I ran an ANOVA, but am not sure if that is the right approach. This is a work project, not a HW assignment.

Any help would be much appreciated.

Thanks!

So, no two graders rate the same students, instead there are 6 distinct groups, each comprising 12 students?
Oneway analysis of variance indeed looks like the way to go then.

With kind regards
