Statistical relevance in passages

When presented with a passage that shows the results of an experiment and they ask a question that asks to draw conclusions, do I have to look for an asterisk showing statistical significance?
I've just been doing a few passages in the bio section of TBR, and some passages say no conclusions because there is no asterisk while some questions give an answer even with no asterisk. So I was just wondering what the case is for the actual mcat. Thanks.

Normally I apply common logic to see if something is statistically significant or not, unless it is directly given. For example, the difference between 1.3024 and 1.3025 is unlikely to be statistically significant in most cases. There are times when a "small" difference is expected, and thus statistically significant. I make the judgment call based on context. If I expect a very small difference, then that difference is significant. If I don't, then any (small) differences are insignificant.
