Really good video! thanks for it. i have some questions about analyses. If I have more groups (5 groups in my case, may i use one-way ANOVA?) Another question: the minimo that I need are 3 replicates, but if i have just 2 replicates, what test do you sufest to use?

In the multiple comparison page, under summary, we see 4 stars for "control vs drug B" & "drug a vs drug B". Yet in the plot, you add only 1 star. Which one is the correct one? Or what is the significance of the 4 stars in the analysis page?
@DoryVideo Жыл бұрын
Most state that anything less than 0.05 is significant, therefor multiple stars are not relevant.

@DoryVideo5 жыл бұрын
The number of asterisks are up to the user. Personally I usually report any significance less than the threshold set in the study as a single asterisk, this is common practice in the scientific community.

Thank you, this helped me a lot. However, could you help me figuring out how to showcase the significant differences between groups using letters instead of stars? I have seen graphs were each bar has certain letters on top and I believe that if two given bars do not share these letter, the difference are significant. I still have got no clue how to organize this. I have 5 treatment columns in my case. Please help!

Hey thanks for the video Dr. I am transitioning from SPSS to prism and I have this problem: so I'm comparing three treatment groups of NSAID drugs (drug A, drug B, and Placebo COLUMNS) and within each group there are 10 subjects (SUBCOLUMNS), each subjects has their pain latency measured every 30' in a span of 3 hours (ROWS). I can't seem to find a way to input the data with the COLUMN data type so I've inserted it in the grouped data type, each subject's data was placed in a subcolumn (the three main column being the type of treatment), I wanted to test for normal distribution but what it does instead is analyze the subcolumn (the pain latency of one subject) when what I wanted was the row (the pain latency between subjects). Any idea on what my mistake here was?
@TheLukiBe3 жыл бұрын
I believe the assumption of equal SD should be tested before selecting parametric ANOVA. Is it possible to do it during the one-way ANOVA analysis?

In prism you can test for normality and distribution/variance

Hi James, I have a problem, I was running the test on samples, where I have 3 different measurements for each sample, regarding the results of an ELISA analysis which returns absorbance values. When I run the normality test I get N small. Does this probably depend on the values I enter? They are in the range of 0.1-0.5. Thank you in advance for your reply.
