Preserving the Reliability of a Study

Question 1

Name the three methods of assessing reliability.

Answer 1

1) Split-half method
2) test-retest method
3) Inter-observer reliability

Question 2

What is the split-half method?

Answer 2

Measures internal reliability by splitting the test into two and having the same participant do both halves - if both halves provide similar results, this is to be taken as high internal reliability.

Question 3

Answer 3

Gives the same test to participants on two separate occasions.

Question 4

What is inter-rater reliability?

Answer 4

The extent to which researchers agree on the behaviours identified in an observation.
