Less materials
Time effective
No participant variables

Question 12

Answer 13

Sixth form students at notre dame

Question 17

How will you ensure external reliability? (1)

Answer 17

Test retest

Question 18

What validity issues will be in your study? (1)

Answer 18

Researcher bias

Question 20

Mann Whitney U Test

Question 21

What was the observed value? (1)

Answer 21

221

Question 22

What was the critical value? (1)

Answer 22

138

Question 23

Were the results significant? (1)

Answer 23

The observed value (221) is greater than the critical value (138) so the results are non significant as for this test, the observed value had to be less than the critical value (one failed p<0.05)
This means we accept the bull hypothesis and reject the alternative hypothesis

Question 24

What are the conclusions? (1)

Answer 24

The effect of context on recall performance does not spend on auditory conditions the material was learnt under
No difference

Question 25

Two ways to improve (1)

Answer 25

Participant engagement
- talking during the task
Standardised procedure
- not all students follow rules
- lack of ecological validity
