Hello,
we are doing an experiment where body consistence (weight, proportion of muscles, fat, etc.) are measured. We have 103 respondents, water and banana were given to each of them a then they were measured in 5 different times (time 0, immediately after consuming water or banana, after 30, 60 and 90 minutes). We also have an information about sex od participants.
I would like to measure if there is a statistically significant difference in the mean times between meal/sex,
meal (between-subjects factor, 2 levels)
sex (between-subjects factor, 2 levels)
time (within-subjects factor, 5 levels)
I tried to study a lot of materials and forums but I think I didn't catch the idea well. A tried to follow very nice tutorial for SPSS (https://statistics.laerd.com/spss-t...ated-measures-anova-using-spss-statistics.php, https://statistics.laerd.com/spss-tutorials/mixed-anova-using-spss-statistics.php).
According to this:
* each respondent got water + was measured, each respondent got banana + was measured -> two-way ANOVA with repeated measures
* some of the respondents are males, some of them females -> mixed ANOVA
Am I right, please?
What this the difference in R code using aov() function? I found command like
aov(dependent.variable ~ between * within + Error(subject/within))
Does this code correspond to two-way ANOVA with repeated measures or to mixed ANOVA?
I would be very grateful for any response!
