I did an experiment and afterward conducted an ANOVA where I got results that were not significant:
Df Sum Sq Mean Sq F value Pr(>F) type 1 1.91 1.910 0.735 0.3951 sex 1 7.48 7.482 2.878 0.0955 . type:sex 1 0.05 0.048 0.018 0.8927 Residuals 54 140.37 2.599
I'm mostly interested in the type*sex interaction here.
My sample size is 16, pretty similar to other studies in this field (sample size usually 20 more or less). I've read that it's pointless to do a power analysis after the fact so now I'm wondering what sort of analysis I can do to test if my sample size was large enough to detect an effect.
When looking at the graphs they are in the expected direction for this variable and also for two other (out of 3) variables however they all similarly have very high p-values.
