  1. Mock exam feedbackResearch Methods

  2. Question 1(a) • Hypothesis must be operationalised • Must be written as a prediction • Must be directional • Participants who are instructed to repeat the words verbally many times will recall a higher number of words than participants who are instructed to read the words only once

  3. Question 1(b) • Question is asking for control of extraneous variables • Same level of word difficulty (words are comparable on every factor) so will equally easy to remember; one list will not be easier, the other harder to remember. Ensure recall is caused by memory strategy.

  4. Question 1(c) • IV – instructions Ps were given – either to repeat the words many times verbally, or to repeat them only once • DV – number of words correctly recalled

  5. Question 1(d) • Volunteers are often a certain type of person (extrovert, helpful) or with a lot of time on their hands (unemployed, retired) and therefore sample may not be representative of target population and cannot generalise results of study to wider groups of people.

  6. Question 1(e) • 2 marks – state 2 things • 1 mark – controlled environment • 1 mark – IV is manipulated by experimenter/researcher

  7. Question 1(f) • Must refer to data in the table • Must report not just findings but also conclusions • Say as much as you can to explain conclusions (2 marks = 2/3 minutes) • What this tells us about memory

  8. Question 2(a) • (i) Caused a lot of problems – correct answer A (question asks for experimental design) • (ii) The use of an independent groups design where each group is exposed to a different condition of the IV means that as the only thing different between the 2 groups was whether they had sensitivity training or not, then it must be that which caused the findings. (2/2)

  9. Question 2(b) • (i) mean • (ii) 1 mark for description, 1 mark for elaboration • Strength – it is calculated from all the values that make up the data therefore is a more sensitive measure of central tendency • Weakness – if there are any outlying, abnormal values in the data then the mean can be easily distorted by these extreme scores

  10. Question 2(c) • Very poorly answered – need to review measures of dispersion • SD tells us about the variation in the data from the 2 groups • SD tells us that those Ps who were in the group that received sensitivity training appear to have wider variation in their sensitivity than the group that received no training.

  11. Question 3 • Easy • Validity concerns how well a study measures what it claims to measure. • Only 1 mark so no need for more elaboration
