Answer 3

how reliable your data is based on if you can repeat it and get the same results. If you get vastly different results, it’s probably not an accurate practice. This method takes a long time because you need to have multiple measurements to make it valid.

Question 4

Answer 4

1) The two observers must use the same behavioral definition

2) They must observe the same response

Question 5

Behavior analysts use ___ ______ when they can compare each observation of two observers.

Answer 5

trial reliability (can always use this method with interval and time sample recording)

Question 6

Behavior analysts use ________ _______ when they can only compare the total observations.

Answer 6

frequency reliability

Question 7

Three ways you can use trial reliability

Answer 7

1) interval and time sample recording
2) checklist (setting a table, all at once checking)
3) event-recording checklist (a checklist for a tutor of what she needs to do)

Question 8

Answer 8
