experiments

Question 1

what is independent measures

Answer 1

pps only take part in one condition

Question 2

strengths and weaknesses of independent measures

Answer 2

no risk of order effects, high internal validity
less risk of demand characteristics

high risk of individual differences, affecting results
more time consuming so it takes longer to reach conclusions

Question 3

what is repeated measures

Answer 3

pls take part in all experimental conditions

Question 4

strengths and weaknesses of repeated measures

Answer 4

more economical, less particiapnts and easier sampling process
no risk of individual differences affecting results, so increasing validity

weakness-
high risk of order effects, lack of validity
more risk of demand characteristics as more likely to be able to guess the aim of the study

Question 5

what is matched pairs

Answer 5

pps are matched by key characteristics

Question 6

strength and weakness of matched pairs

Answer 6

no risk of order effects, increasing validity
no risk of individual differences increasing validity

weakness- difficult to successfully put in place especially with larger samples, less economical

Question 7

strenghts and weaknesses of lab

Answer 7

strenghts
high control over EV’s- scientific
easier to standardise- internal relaibility

weakness
low ecological validity
increased risk of demand characteristics

Question 8

strenghts and weaknesses of quasi

Answer 8

strengths
-means IV does not have to be manipulated, so more ethical
can study a unique/hard to reach group

weaknesses-
small sample, high risk of indivual differences
often controlled environment so low ecological validity
