Unit 4 Quiz

Question 1

A mean of 80% agreement means the data are accurate.

Answer 1

False

Question 2

Bar graphs sacrifice the presentation of the _________ and _________ in behavior.

Answer 2

Variability, trends

Question 3

Behavior change is considered a __________ and __________ process; therefore it is important to maintain direct and continuous contact with the behavior under investigation.

Answer 3

Dynamic, ongoing

Question 4

For this scenario, select the most appropriate data display to communicate quantitative relations: During an analysis you are interested in evaluating the effects of the independent variable on a dependent variable that can only occur once per measurement period. For example, the participant either engages in the behavior or does not, therefore your data collection is limited to recording a yes or a no.

Answer 4

Cumulative record

Question 5

For this scenario, select the most appropriate data display to communicate quantitative relations: You are interested in comparing the effects of intervention A with intervention B on the aggressive behaviors displayed by one student in your classroom. In other words, you are interested in looking at the same behavior under different and alternating experimental conditions

Answer 5

Line graph

Question 6

Logarithmic scales are well suited to display and communicate __________ change.

Answer 6

Proportional

Question 7

Measurement __________________ are data that give an unwarranted or misleading picture of the behavior because of the way measurement was conducted.

Answer 7

Artifacts

Question 8

Observer ______ is an unintended change in the way an observer uses a measurement system over the course of an investigation.

Answer 8

Drift

Question 9

Observers should not receive systematic training prior to data collection, because training will cause observer bias.

Answer 9

False

Question 10

Observers should receive feedback about the extent to which their data confirm or run counter to hypothesized results or treatment goals.

Answer 10

False

Question 11

On a cumulative record, the steeper the slope, the __________ the response rate.

Answer 11

Higher

Question 12

Scored-interval IOA is recommended for behaviors that occur at relatively _________frequencies; unscored-interval IOA is recommended for behaviors that occur at relatively _____________frequencies.

Answer 12

Low, high

Question 13

This type of graph provides a standardized means of charting and analyzing how the frequency of behavior changes over time:

Answer 13

Standard celeration chart

Question 14

True values for some behaviors (for example, compliance) are difficult to assess, because the process for determining true value must be different from the measurement procedures used to obtain the data one wishes to compare to the true value.

Answer 14

True

Question 15

Which is a false statement about the requirements of IOA?

Answer 15

IOA observers must always score videotapes together

Question 16

Which of the following is not a factor that contributes to measurement error?

Answer 16

Well trained observers

Question 17

Which statement is true?

a. Graphs are not considered an effective source of feedback to the person whose behavior change is represented.
b. A cumulative record should be used if the target behavior can only occur once per measurement period.
c. One may connect data points on a line graph when there is a condition change line, when a significant span of time has passed without data collection, across discontinuities of time, if data were lost or destroyed, or if data represent follow-up or post-check measurements.
d. Overall response rate refers to the highest rate of response over a given time period.

Answer 17

B.

Question 18

__________ is the degree to which two or more independent observers report the same observed values after measuring the same events.

Answer 18

IOA

Question 19

__________________ between observers is the most common convention for reporting IOA in ABA.

Answer 19

Percentage of agreement

Question 20

__________________ is the biggest threat to the accuracy and reliability of data.

Answer 20

Human error
