When comparing a study with a level of significance of 0.05 with a study having a level of significance of 0.01,the researcher knows that the study with the level of significance of 0.05 is more likely to have a:
A) correct null hypothesis.
B) generalizable finding.
C) Type I error.
D) Type II error.

Question

Quizplus · Accepted Answer

A study with a level of significance of 0.05 is more likely to have a Type I error, meaning it is more likely to reject a true null hypothesis. This is because the threshold for rejecting the null hypothesis is lower in a study with a significance level of 0.05 compared to a study with a significance level of 0.01. Therefore, there is a higher risk of falsely rejecting the null hypothesis in the former study.
