Hi everyone! What statistical analysis method would you use if you like me had repeated an experiment 3 times. The experiment consist of control and treated with drug A, B or C. The experiment had 3 replicates per treatment group (3xcontrol, 3xdrug A etc). The experiment was repeated two more times, so in total I have results of three similar experiments (the same setup). Would you go for multivariable ANOVA?
Thanks for the help!
Elizabeth Pavez Lorie Just to clarify, do you wish to combine the data from the three experiments into a single analysis, or do you intend to analyze the data from the three experiments separately?
If you want to combine data from the three experiments for a single analysis, are you interested in testing for differences across experiments? In other words, are you treating 'experiment' as an independent variable?
Hi,
For each of the experiment Run Generalized Linear Mixed Model or Generalized linear repeated model, For each of the Expts. there are two levels of a factor I.e Control and Drug, There are 3 replicates or repeated measures.
Hello Elizabeth Pavez Lorie. People in different disciplines sometimes speak somewhat different dialects of statisticalese. I want to make sure I understand what you mean. When you say you have 3 replicates per treatment group, I think you mean 3 independent observations, is that right? In other words, your data file looks something like this, with each row holding an independent observation:
ID Exp Group
1 1 Ctrl
2 1 Ctrl
3 1 Ctrl
4 1 A
5 1 A
6 1 A
7 1 B
8 1 B
9 1 B
10 1 C
11 1 C
12 1 C
13 2 Ctrl
14 2 Ctrl
15 2 Ctrl
16 2 A
17 2 A
18 2 A
19 2 B
20 2 B
21 2 B
22 2 C
23 2 C
24 2 C
25 3 Ctrl
26 3 Ctrl
27 3 Ctrl
28 3 A
29 3 A
30 3 A
31 3 B
32 3 B
33 3 B
34 3 C
35 3 C
36 3 C
Thanks for clarifying.
Hi,
As far as I could understand you have 4 factors (1Control + 3 factors) to compare, and you have 3 observations for each?
Please let me know,
