A researcher reports that there is a significant difference between two treatments at the 0.05 level of significance (alpha is 0.05). This means that if the researcher repeated the experiment, there is a 95% chance that the same decision would be reached. The difference obtained in the experiment is at least 5% larger than the standard error. There is a 5% probability (or less) that the difference occurred simply by chance without any treatment effect. The average score for one treatment is at least 5% higher than the average score for the other treatment.

If a repeated-measures study shows a significant difference between two treatments with ? = .05, then you can be sure that:

A researcher comparing the means of a treatment and control group obtained a 95% confidence interval for the mean difference (experimental – control) of (-1.5, 3.2). Which of the following statements is correct? There is no statistically significant difference between the means of the groups at the .05 level. There is a statistically significant difference at the .05 level of up to 3.2 points between the means of the groups. There is a 95% chance that there is no difference between the means of the groups. We are 95% confident that the mean of the experimental group is between 1.5 and 3.2 points higher than the mean of the control group.
