Low control over extraneous variables

Question 5

Observation controlled

Answer 5

High reliability

Control environment

Control over extranuous variables

Question 6

Observation naturalistic

Answer 6

Low reliability

Real life environment

Low control over extraneous variables

Question 7

Ways to test reliablity

Test re-test

Answer 7

Ppts given a task to measure and complete (context)

The same ppts are given the same task (context) after a time delay e.g 2 weeks

Create the results from each test (context)
Using stats test

Strong positive correlation of above 0.8+ shows high reliability

Question 8

Ways to test reliability of observations

Inter-observation reliability

Answer 8

Reliability of observations can be checked by using 2 observers

2 observers create and trained on how to use behaviour categories

2 observers conduct observation separately watching exact same behaviour for same amount of time but recording observations independently

Tallies from 2 observers should be compared and correlated with appropriate stats test

Strong positive correlation of +0.8 shows high reliability
