Question 1192838: Meaning of “statistically significant.” When asked to explain the meaning of “statistically significant at the α=0.01 level,” a student says, “This means there is only probability 0.01 that the null hypothesis is true.” Is this an essentially correct explanation of statistical significance? Explain your answer.
Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! No, it means that the probability or likelihood of getting the value obtained is only 1% if the null hypothesis were true. A lot of the words are the same, but the different order of them is important. We don't know for a fact that the null hypothesis is or is not true. If it is true, then what we saw happens only 1% of the time, and we have decided a priori that we would consider such a result as so unlikely as to discard the null hypothesis.
