D)use null hypothesis significance testing instead of confidence intervals.

Question

Quizplus · Accepted Answer

Researchers should be aware of limitations associated with null hypothesis significance testing, as this method only tells us whether an effect is statistically significant, but does not provide information about the size or practical significance of the effect. Therefore, researchers should also report measures of effect size along with the results of significance testing. Additionally, researchers should consider alternative methods such as confidence intervals, which provide a range of possible values for the true effect size with a given level of probability. Using the most complicated analysis or relying solely on null hypothesis significance testing can lead to overcomplicated or incorrect conclusions.
