Question 2

What is reliability?

Answer 2

-It is how consistent a test can be repeated producing the same results with the same group of participants at some point in the future.

Question 3

How can we test validity?

Answer 3

• Concurrent validity: this involves comparing the results to a benchmark test results and if they are the same they are valid
• Predictive validity: This is comparing future outcomes with the test results predicted and if they match the findings and test is valid
• Face validity: this measure of validity identifies whether the test actually sets out to measure what is supposed to measure.

Question 4

What ways can we test reliability?

Answer 4

• Inter observer reliability
• Test re test reliability
• Split half reliability
