Hi Members,
I have microarray data set of genes with the expression value in 3 experiments. I would like to select the genes whose expression value is high and consistent across all experiments. (ie, the standard dviation should be less). I am searching for a statistical method to solve my issue.


I give a sample table as below,

ID Experiment 1 Experiment 2 Experiment 3
Gene1 10 11 8
Gene2 12 10 11
Gene3 4 12 12
Gene 1000

If i take, the average, In the above set, I may have to take (wrongly) the Gene 3. Since experiment has value just "4", i actually dont prefer it.
