not statistical significant......

Been asked this question this question a lot of times before, "Why my result (s) is not statistical significant though the differences between the control and treated groups are big???"

Please have a look at the standard variation of your data, and most likely that the standard variation for one or all of your experimental group (s) is huge enough to cause your result is not significant though the mean difference between your experimental groups is big.

Try to think of ways to improve your experiment's data accuracy and precision......
