Question 3

What is Predictive Validity?

Question 5

Question 7

Question 8

What is reliability?

Answer 8

• Means that 2 or more measurements/observations of the same event will be consistent with each other.

Question 9

What is Test-Retest Reliability?

Answer 9

• A measure of whether something varies from 1 time to another.

What is Inter-rater Reliability?

Answer 10

• When more than 1 interviewer is used to collect data for the research study.

Question 11

What is generalisability?

Answer 11

• Whether results or findings of research can be transferred to other situations or people.
