Experimental designs!

Question 1

types of experimental design

Answer 1

Repeated measures
Independent groups
Matched pairs

Question 2

Independent groups

Answer 2

Only perform in one condition of the IV

Question 3

Ind group str

Answer 3

No order effects
Limits demand characteristics: less likely to guess aim of study

Question 4

Ind group lim

Answer 4

Participant variables: diff abilities of participants can cause changes to DV

More partipants needed

Question 5

Ind group solution

Answer 5

Random allocation solves partcipant variables: same chance of being in each condition

Question 6

Repeated measures

Answer 6

Same participants in all conditions of the IV

Question 7

repeated measures str

Answer 7

eliminates participant variables
Fewer participants needed- less time consuming

Question 8

repeated measures lim

Answer 8

order effects
eg boredom or practice effect

Question 9

repeated measures solution

Answer 9

counterbalancing

Question 10

Matched pairs

Answer 10

Pairs of participants are matched on some variable that has been dound ti affect the DV

One member does one condition
One member does the other

Question 11

matched pairs strengths

Answer 11

no order effects

Question 12

matched pairs limitation

Answer 12

Time consuming, expensive
Large pool of potential participants needed
Difficult to know variables are appropriate for matching

Question 13

matched pairs solution

Answer 13

Conduct a pilot study to consider which key variables might be important when matching
