question 72

Multiple Choice

A researcher conducts a single-sample t test and finds statistical significance at the 0.01 level.The effect size is then calculated and found to be 0.04.What might be concluded about the findings?

• A) The findings are statistically significant, but the effect size indicates that they may not be practically significant.A very large sample may have been studied, driving up the test statistic value.
• B) The findings seem flawed because without a substantial effect size, it is not possible to find statistical significance.
• C) The findings are both statistically and practically significant in this case, as the effect size indicates a medium effect, and the 0.01 level of significance is rather impressive.
• D) These findings are exciting because statistical significance was found with a very small effect, indicating that the results are real and the chance of a Type I error are low.
