Question 1
Lecture notes and learning
Researchers wanted to see whether providing learning aids during a lecture would help students. Students attended an audio lecture on how car brakes function. Before the lecture, students were given either a skeletal outline (with headings and subheadings) or no learning aid at all (they were given notepaper). After the lecture, students were given a short-answer test that assessed their understanding of how car brakes function.

Identify the experimental/research design used in the lecture notes and learning study.
(1)
Answer
Explain how one participant variable could affect the findings of the lecture notes and learning study.
(2)
Answer
Explain one way the researchers in the lecture notes and learning study could make the study as generalisable as possible to the target population of students.
(3)
Answer
The researchers in the lecture notes and learning study decided to carry out a Mann-Whitney U test on the data.
Complete Table 1 and calculate Mann-Whitney U for the data in Table 1.

Answer
The researchers of the lecture notes and learning study need to decide whether to accept or reject their null hypothesis. They have been warned not to make a Type I error when doing this.
Explain to the researchers what a Type I error would be in the lecture notes and learning study.
(2)
Answer
The researchers in the lecture notes and learning study are interested in publishing their work in the British Journal of Educational Psychology.
(Source: statement adapted from the Author Guidelines for the British Journal of Educational Psychology, published by the British Psychological Society (2015))
Explain what the peer review process would involve for the researchers in the lecture notes and learning study, including a consideration of the likelihood of their findings being published.
