Question 1

The pattern of this chart shows:

A) Change in slope, no change in trend across phases
B) Drift and change in level
C) Change in slope, change in level
D) None of the above

Answer 1

A

Question 2

The pattern of this chart shows:

A) Change in slope
B) Drift and change in level
C) No change in level but change in slope
D) None of the above.

Answer 2

B

Question 3

Directionality in the data-whether within or across phases-is called slope.

Answer 3

False

Question 4

Visual analysis of data is particularly reliable because one does not have to be concerned about the possibility of autocorrelation.

Question 5

Can you have a stable trend if the line made up of linked data points is continuously up and down? Draw a diagram indicating your answer.

Question 6

What do you make of a situation where the client's behavior changes from bad to good to bad during baseline? Should you start the intervention with a sense of stability, if curvilinear, behaviors?

Question 7

Trend across phases is called:

A) Variability
B) Slope
C) Drift
D) None of the above
