Why do you use significant digits when dealing with measurements?
Measurements need to be specific so we use significant digits.
What does it mean to say the difference between the means of group a and b is statistically significant?
There is an established statistical point for most comparisons or measurements that is so small that differences at or below it are considered to be "random", "predictable", or "meaningless". If a difference between A and B exceeds this point, it is said to be "significant", which does not necessarily mean "important" or "huge" - just "significant".
