In a journal article,the authors report that the result is significant at the .05 level.This means that:
A)the researchers know that the results were not obtained by chance and that the difference between the experimental and the control group is "real."
B)the probability that the result is due to "real" differences between groups is 5 times in 100 repetitions of the study.
C)the results failed to support the hypothesis of the study,although the researchers may want to do further studies.
D)the probability that the result occurred by chance is extremely low and the probability that the difference is "real" is overwhelming.

When a result is significant at the .05 level, it means that there is only a 5% chance that the result occurred by chance. Therefore, the probability that the difference is "real" is overwhelming, and the researchers can be confident that the result is not due to chance.

In a Journal Article,the Authors Report That the Result Is
