IOA

Question 1

What is IOA?

Answer 1

IOA data tells us how reliable the observations were by comparing each observers score to see if the date ‘agree’ with each other.

Question 2

IOA data ensures that reported differences in behaviour are not due to:

Answer 2

1. Changing definitions.
2. Observer bias.
3. Measurement error.

Question 3

What is the IOA formula for continuous recording measures?

Answer 3

Smaller score/Larger score x 100.

Question 4

What is the IOA formula for time sampling?

Answer 4

Agreements/ Agreements and Disagreements x 100.

Question 5

Factors affecting accuracy of IOA scores:

Answer 5

1. Complexity of data sheet/coding
2. Expectancies of behaviour change.
3. Feedback from researcher (can affect how they record data on subsequent observations).
