Hi, all of your videos are awesome! Thank you! I have a question about the t test and anova. So I have a dataset that contains 9 samples, C1, C2, C3, H1, H2, H3, L1, L2, L3, from the name you can see they are 3 groups with 3 replicates. So if I want to know the difference between the C, H and L groups, can I use t- test for each group? Like C groups and H groups, C and L groups. I saw your previous about t test, must be 2 samples, but I have 6 samples to compare(C1, C2, C3, H1, H2, H3), they are just 2 groups, how can I do this? Any information will be highly appreciated!
