1. A school psychologist wanted to measure the number of times a student has a crying and yelling fit in class. He decided to count how many times the classroom teacher told the the student to "stop" their behavior. All the following are true about his measurement plan EXCEPT:

A)	It may be affected by measurement bias.

B	It is less valid because counting crying fits may not reveal the important dimension of duration.

C)	It is valid because the teacher can easily count the number of times she says "stop!"

2. Observations of a child's skin picking behavior were recorded using frequency counting during discrete trial training sessions. Two staff were present and calculated an inter-observer agreement of over 90%. At the end of the week, the staff compared the number of new wounds to the frequency of skin picking and decided that the frequency of skin picking underestimated damage to the child's skin. They decided to change their measurement system because of a problem with ________.

A)

Validity

B)	Reliability

C)	Measurement Bias

3. A teacher is trying to improve the reliability of her observations of a student in her class by having two classroom ed. techs observe and record at the same time each day. Both techs are using the same type of data sheet to record the behaviors and have a very clear definition of the target behavior. They will be sitting in different places in the classroom to observe the student. They will not be able to see each other's data sheets until after the observation session has concluded. What factor would most likely cause inter-observer agreement to decrease in this example?

A)	They may not be able to detect all the same behavioral events

B)	Their measures may not be independent of each other

C)	They may be using different data measurement methods

4. A school psychologist is trying to determine the number of observations that she will need a second observer to record the behaviors of a student during a functional communication training protocol. She estimates five baseline measurements, nine treatment measurements, and five withdrawal measurements. What percentage of sessions should include IOA observations for this study?

A. 10%

B. 33%

C. 80%

5. A researcher is trying to determine which method of IOA would be best to use with a study which attempts to reduce the amount of times a student strikes himself in the head with a closed fist. The behavior occurs at high frequencies and the researcher would like to use an interval recording method. Which method would likely produce the most reliable IOA results?

A)	Unscored interval IOA

B)	Scored interval IOA

C	Total interval IOA
