A researcher measured people’s physiological reactions while watching horror films and compared them to when watching erotic fil
ms and a documentary about wildlife. Different people viewed each type of film. The resulting data were normally distributed and the variances across groups were similar. What test should be used to analyse the data?
I believe that the test that should be used in order to analize these data is the one-way analysis of variance (ANOVA). This test is used to measure the differences between 2 or more independent groups.
