Hello,

I get confused about how to select the appropriate statistical test.

A researcher measured the same group of people's physiological reactions while watching horror films and compared them to when watching comedy films, and a documentary about wildlife. The resulting data were normally distributed. What test should be used to analyze the data?

Independent analysis of variance (my choice); Repeated measures analysis of variance, Kruskal-Wallis test, or Friendman;s ANOVA (not a normal distribution, so I ruled this out).
