: Procedures for Collecting Data

1. List, define, and give an example (not one from the text) of each of the 7 dimensions of the data collection system.

2. (a) What are anecdotal reports? (b) What are the advantages and disadvantages to this approach for data collecting?

3. (a) Interval Recording is often used with behaviors such as on-task behavior and tantrums. Review the information under "Interval Recording" and explain in 3 or more sentences how this method is conducted.

(b) Ms. Hahn observed Larry during math for 30 minutes.She selected a 10-minute time frame to do interval recording. Within that 10 minutes, every 15 seconds she looked to see if he was on-task. What percentage of time was Larry on-task?

Percentage of Time on Task (15-second intervals in 10 total minutes)

+ = on-task o = off-task

+	O	+	+	O	O	O	+	+	O
O	+	+	+	+	O	O	O	O	+
+	+	O	+	O	O	O	O	O	+

4. Event recording, interval recording (time sampling), duration recording, and latency recording are the 4 primary recording systems used to observe behavior. Give an example of a situation in which each would be most useful (total of 4 examples).
