Question
Week 5 Project Read the following hypotheses:
•Confidence in recall differs depending on the level of stress.
•Recall for participants in high-stress conditions will deteriorate over time.
•Boys will have higher levels of confidence than girls.
In a 1- to 2-page Microsoft Word document, for each hypothesis listed above, indicate:
•Describe how a Type I error might occur, given the context of the assignment. Describe how a Type II error might occur, given the context of the assignment (i.e., if my hypothesis was that women had higher levels of empathy than men, a Type I error might occur if I found significant results with women scoring higher on empathy than me, when, in the general population that is not the case; a Type II error might occur if I found no differences in empathy between men and women when, in the general population women score higher on empathy than men).
•Whether the appropriate analysis would be a one-tailed test or a two-tailed test
Explanation / Answer
According to the definitions of Type 1 error and Type 2 error listed below, the table gives the solution(s):-
Type 1 error: False Positive - the results show that the hypothesis is true, when actually that is not the case
Type 2 error: False Negative - the results show that the hypothesis is false, when actually that is not the case
Case Type 1 error Type 2 error 1 or 2-tailed test Confidence in recall differs depending on the level of stress When the data shows significant results that the confidence is NOT the same across levels of stress. But, actually the confidence level doesn't vary significantly across stress levels. When the data shows significant results that the confidence is the same across levels of stress. But, actually the confidence level varies significantly across stress levels. 2-tailed (just talks about difference, NOT lesser or greater) Recall for participants in high-stress conditions will deteriorate over time When the data shows significant results that the recall under high-stress deteriorates with time. But, actually recall doesn't significantly decrease under high-stress conditions. When the data shows significant results that the recall under high-stress does NOT deteriorate with time. But, actually recall decreases significantly under high-stress conditions. 1-tailed (talks about lesser) Boys will have higher levels of confidence than girls When the data shows significant results that boys have higher levels of confidence than girls. But, actually the confidence level doesn't vary significantly across gender. When the data shows significant results that boys do NOT have higher levels of confidence than girls. But, actually the confidence level varies significantly across gender. 1-tailed (talks about greater)Related Questions
