I have 50 plants which are studied for 3 generations and have fruits with different number of seeds. I want to check if there is any change in number of seeds in each plant. Like if in plant no.1 the seed numbers are decreasing or increasing or almost constant. What should be used in such a case?
Hey, you seem to have repeated measurements but no control condition / no groups? You can only test aggregate results, like the mean for each generation of those 50 plants. In that case go for the repeated measures ANOVA if the requirements are met: ruclips.net/video/pGLY-xJ5_ss/видео.html One flaw in your study design is the lack of a control group that reviewers will most certainly criticize. Single plants can only be evaluated using descriptive statistics, which will be a good basis for formulating hypothesis and doing hypothesis testing with a proper study design. Cheers, Björn.
@@statorials Thankyou for the reply. I want to check if the seed numbers are decreasing or increasing every generation. For example plant1 has 10 seeds in year1, 12seeds in year2, 11 seeds in year3. Like this I have 50 plants. How can I add a control to this experiment? Your suggestions are valuable and thanks for making these amazing videos, it is exactly what I needed✨️
It sounds like you should do a repeated measures ANOVA to check if the means increase or decrease over time. A control variable would go into the covariates box in the repeated measures ANOVA. Cheers, Björn.
