Question 13

Can be marked according to the
needs of the behavior analyst as any
specified recorded observation
periods, over a period of time

Answer 13

X-Axis Units

Question 14

Equal movements up the Y-axis represent
equal increases in the behavior; should be
expressed in whole time units

Answer 14

Y-Axis Units

Question 15

Runs from zero up to some number which is

chosen by the creator of the graph

Answer 15

Y-Axis Range

Question 16

An individually measured value of the target

behavior (the DV) at a given point in time

Answer 16

Data Point

Question 17

It represents the relationship between the IV and the DV.

Answer 17

Data Path

Question 18

Represent a major change in the IV, OR
a major (usually permanent) change in the
environment

Answer 18

Phase Changes

Question 19

A solid vertical line placed at a point along
the X-axis indicating the point in time that the
phase change occurred

Answer 19

Phase Change Lines

Question 20

Represent a minor change in the IV, OR
a minor (usually temporary) change in the
environment

Answer 20

Condition Changes

Question 21

A dotted vertical line placed at a point along
the X-axis indicating the point in time when
the condition changed

Answer 21

Condition Change Lines

Question 22

States which time periods are represented

by each successive data point

Answer 22

X- Axis Label

Question 23

States which response measure was used to
measure the dependent variable – the target
behavior

Answer 23

Y- Axis Label

Question 24

Brief labels, placed at the top of the chart,
that identify each separate major phase of
treatment

Answer 24

Phase Labels

Question 25

Mark changes occurring within a phase

Answer 25

Question 31

The extent to which measures of behavior under the same environmental conditions diverge from one another

Answer 31

Variability

Question 32
