Obtaining a probability value of .05 gives us confidence that the findings are not the result of chance but does not eliminate this possibility. This means that there is still a chance that the difference between groups is due to chance fluctuation, but it is unlikely. It is important to keep in mind that statistical significance does not equal practical or meaningful significance.
