WORKSHEET
Instructions: The purpose of this project is (a) to give you practice calculating IOA with frequency recording and interval recording, and (b) to have you describe the benefits and potential problems with these two types of IOA
1. Frequency recording
2. Partial interval recording
For frequency recording and partial interval recording, you will make-up data for your pretend “Observer 1” and your pretend “Observer 2”.
FOR FREQUENCY RECORDING IOA Assignment:
For frequency recording, make-up a frequency count between 1-10 for “Observer 1” Then, make-up a frequency count between 1-10 for “Observer 2.”
Now, calculate inter-observer agreement (IOA) for your made-up data using an appropriate method. Using your made-up numbers, calculate an IOA. Make sure to include:
· IOA method used
· The IOA formula for that method, and
· Your calculations
INTERVAL RECORDING IOA Assignment
For partial interval recording, make up a data for “Observer 1”. Then, make-up data for “Observer 2”.
| Interval | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| Observation #1 | |||||||||||||
| Observation #2 |
Now, calculate inter-observer agreement (IOA) for your made-up data using an appropriate method. Using your made-up data, calculate an IOA. Make sure to include:
· IOA method used
· The IOA formula for that method, and
· Your calculations
WRITE OUT BENEFITS AND PROBLEMS
For each of the 2 methods of IOA you used, write a list of the follow:
· Benefits of each IOA
· Potential problems of each IOA
FINALLY, WRITE A BRIEF SUMMARY
Write a brief summary of your findings talking about the differences between the 2 IOA that you calculated.
