I have a two-sample t-test where the t-statistic is equal to the critical t-value (at three decimal points) at a p-value of 0.05. does this mean i reject the null hypothesis or the opposite? thank you so much!
The traditional tests says that the probability has to be less than 0.05, so this is not statistically significant.
However, this shows up the problem of being forced to make a dichotomous yes/no decision for statistical significance. Are you really going to make a decision one way or the other when your answer could be changed by one person (or whatever you're measuring) moving by 1 point.
