Design Of Experiments 1

Question 1

Laboratory experiment

Answer 1

-allowed background noises/ distractions to be reduced/ eliminated
-participants tested one at a time
POSITIVE- highly controlled, rate errors
NEGATIVE- setting is artificial so answers could be fake

Question 2

Field experiment

Answer 2

-conducted in a participants natural environment, leads to more realistic behaviour
POSITIVE- realistic
NEGATIVE- EVs such as background can affect results

Question 3

Natural experiment

Answer 3

-DIFFERENCE BETWEEN THIS AND FIELD IS THAT IT IS NOT SET UP BY RESEARCHER, OCCURS SPONTANEOUSLY IN THE REAL WORLD
POSITIVE- ethical view, experimenter Not responsible for anything that happens, so ideal for studying harmful situations
NEGATIVE- impossible to control EVs, no random allocation to conditions

Question 4

Experimental design

Answer 4

-way participants are allocated to conditions of the study

Question 5

Repeated measures

Answer 5

-all participants must complete all conditions of experiment

Question 6

Independent groups

Answer 6

-participants are randomly divided into groups, and each group takes part in a single condition

Question 7

Matched pairs design

Answer 7

-two separate groups of participants could be created by matching participants up on important characteristics such as age or ability level

Question 8

Control condition

Answer 8

-condition used simple for comparison, used as BASELINE
