Mock Research Methods

Question 1

What are 3 experimental designs

Answer 1

Independant groups
Repeated measures
Matched pairs

Question 2

What does operationalise mean

Answer 2

To be precise and clear about what’s being manipulated and measured. To make it testable and repeatable

Question 3

What are investigator effects

Answer 3

Bias from the investigator, unconscious influence

Question 4

How do you get rid of investigator effects

Answer 4

Randomisation

Question 5

Matched pairs design

Answer 5

•Pairs are matched based on similar variables, one of each pair is placed into a different condition
+ reduces p variables (bc similar ppl r matches)
+ No order effects (only one condition)
- time consuming and expensive
- impossible to match ppl exactly

Question 6

Repeated measures design

Answer 6

The same p in both conditions
+ reset p requires
+ no individual differences
- order effects

Question 7

How do you deal with order effects

Answer 7

Counterbalancing
(sample split into 2 groups, completed conditions in diff orders)

Question 8

What are measures of dispersion

Answer 8

Standard deviation
Range

Question 9

Independent groups

Answer 9

Different p put in each condition
+ no order effects
+ less demand characteristics
- more p= more time and cost
- individual differences can change results
