When I begin to collect all my life span data, I found a big problem. In all the tests, the mean life span of normal N2 control group are 25.64days, 24.72days,20.19days ,17.95days and 26.64days separately. Only the 17.95days was accordance with the public data, the others reached the longevity line.
I am looking for ways to solve the problem.
Could you give me some pieces of advice?
How to explain and which facts should I pay more attention to solve such a problem?
