Reliability and Validity

Question 1

What is Test-Retest Reliability?

Answer 1

The extent to which a procedure can be easily replicated using the same participants so the consistency can be checked

Question 2

What is Inter-Rater Reliability?

Answer 2

The extent to which different researchers are likely to record similar findings using the same procedure

Question 3

How can we improve reliability?

Answer 3

Remove extraneous variables or better operationalisation

Question 4

What is removing extraneous variables?

Answer 4

Removing variables which if left uncontrolled could randomly affect the DV

Question 5

What is better operationalisation?

Answer 5

Making the IV and DV operationalised more clearly

Question 6

What is Reliability?

Answer 6

The extent to which a procedure produces consistently similar findings using rhetorical same participants when repeated

Question 7

What is Internal Validity?

Answer 7

The extent to which a study measures what it intended successfully

Question 8

What is External Validity?

Answer 8

The extent to which the findings of a study can be successfully generalised to other settings, wider populations and over time
