I have 3 variables that have been measured on 4 occasions and a sample size of 16. I was considering a repeated measures MANOVA to ascertain if the changes over time were statistically significant. However, I am thinking that my sample size is too small to use a MANOVA in this way. I am considering using 3 separate repeated measures ANOVAs (one for each variable) instead. Just wondering if this is acceptable and/or justifiable. Anyone have ideas?

Thanks.
