Research methods

Question 1

What is independent variable?

Answer 1

It is the variable that you manipulate

Question 2

What is the dependent variable?

Answer 2

It is the variable that you measure

Question 3

What does it mean by operationalisation?

Answer 3

That the variables are clearly defined- they are testable

Question 4

What are extraneous variables?

Answer 4

It is the variable that may effect the dependent variable

Question 5

What are independent group design and what are the weaknesses and strengths?

Answer 5

It is when the participants would be in different groups and only take part in one measure.

Weakness- participant variables, peoples individual differences such as age

Strengths- no order effects, wouldn’t impact second choice as done only once

Question 6

What are repeated measure design and what are the weaknesses and strengths?

Answer 6

Participants take part in both experiments

Weakness- there are order effects, taking part in first condition could impact your second response

Strengths- there are no participant variables

Question 7

What are matched pairs design and what are the weaknesses and strengths?

Answer 7

Two groups of participants are matched key characteristics for the study

Weakness-

Strengths-

Question 8

Field experiment definition and weakness + strengths

Answer 8

The independent variable is in a natural everyday setting but the researcher still manipulates the independent variable

Weakness- ethical issues with consent and you can’t control the extraneous variables

Strengths- valid and authentic as in natural environment and they don’t know they are being tests so cant give socially desirable responses and no demand characteristics
