A Researcher Conducts a Single-Sample T Test and Finds Statistical

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.
