Question 1

operationalising the IV and DV

Answer 1

involves defining how they will be manipulated or measured in the experiment

Question 2

example of operationalising the iv and dv

Answer 2

research question:does caffeine consumption increase memory and performance

Op IV: 5 cups of caffeine or no cups of coffee

Op DV:memory peformance on a test of 20 questions

Question 3

how can these be measured- operationlising IV and DV

Answer 3

intelligence-a score on a standardised intelligence test

memory-a score on a test of free recall

anger-changes in blood pressure, HR or RR

love- frequency of expression of affection

Question 4

controlled experiments

Answer 4

is an investigation methodology that aims to test the effects of an IV on a DV with all other variables controlled

Question 5

extraneous variables

Answer 5

are variables other then the independant variable that may have unwanted effect on the DV

Question 6

controlled variables

Answer 6

variables that are held constant to ensure that the only influence on the DV is the IV

Question 7

confounding variables

Answer 7

unwanted variables are unwanted variables hat affect the DV and results in an investigation, and it cannot be determined whether the IV or the confounding variable caused by the change in the DV

Question 8

between subjects design

Answer 8

when participants are randomly allocated to either the control or experimental condition

Question 9

strength and limitation with between subjects design

Answer 9

strengths
-time efficient bc both groups can be tested at the same time

limitations
-more participants are needed in a between subjects design

Question 10

within subjects design

Answer 10

involves all participants in the sample completing both the experimental and control conditions

Question 11

within subjects design strengths and limitations

Answer 11

strengths
-their is no extraneous variable of participant variables between groups, improving validity

limitations:
their is less control over participant knowledge of the study.

Question 12

mixed design

Answer 12

involves a combination of between subjects design and within subjects design

Question 13

strengths and limitations of mixed design

Answer 13

strengths
difference in participant variables between groups are controlled within subjects design

limitations
their is a high rate of participant withdrawal

Question 14

investigation methods

Answer 14

case studies
correlational studies
classification and identification methods
fieldwork
