experimental design

Question 1

what do the two levels of the iv effect

Answer 1

the conditions of the study

Question 2

experimental designs

Answer 2

independent groups study

repeated measures

matched pairs

Question 3

independent groups design

Answer 3

one group has one condition the other group has the other condition the the results are compared

Question 4

repeatred measures

Answer 4

one group does both conditions and then compare the results

Question 5

matched pairs

Answer 5

one person from each pair is in each group it is the same a independent groups design then results are compared

Question 6

how to control for effects in the designs

Answer 6

to control order effects in repeated measures use counterbalancing

when picking groups for independent groups design use randomization or lottery method

Question 7

controlling situational variables

Answer 7

use standardised procedures so all conditions are the same

Question 8

what does counterbalancing do to the impact of order effects

Answer 8

it spreads the impact across the two conditions equally

therefore the the difference in conditions is due due to manipulation of iv not due to ev or order effects
