Hi, I want to use a one-way random effects anova intraclass correlation on
the following data. 70 subjects, each with 30 measurements of the one
property - their EEG alpha frequency - taken across a 5 minute interval.
I'm looking at both single and average measures for reliability. When
assessing normality of the distribution do I look at the entire data set ie
70*30 measures, or do I look at the single columns of alpha ie 30
distributions of 70 measures each. Is the within subject distribution
important, ie 70 distributions of 30 measures each. Thankyou for your time,
I understand this is trivial but I find the statistic texts i have consulted
quite opaque on this point.
