Quizplus · Accepted Answer

The best option is for Jack to run 20 additional subjects to his experiment in order to potentially obtain a significant outcome. This is a reasonable and straightforward solution that does not compromise the validity of his findings by relaxing the significance level or making assumptions about the results with a larger sample size. Apologizing for the limited sample or making statements about what could have happened with more subjects does not improve the current findings and may weaken the credibility of the study.
