Flashcards in BEHP 5012 Unit 4 A Deck (35):

Visual analysis includes taking an overview of a data display to evaluate its general characteristics before looking at specific data results. A general characteristic of a data display would be the…

Range and continuity of each axis


Visual analysis of data seeks to answer two basic questions. Select which of the following constitute one, or both, of these two basic questions:

X = Was there a statistically significant change in behavior?

Y = Was there a meaningful change in behavior?

Z = To what extent can the change be attributable to a specific environmental change?

Y and Z


Carole has added a response cost procedure contingent on the occurrence of aggression to David’s plan. She has collected data for three months and wants to present these data to the interdisciplinary team in the form that is most easily and quickly analyzed. Which type of data display should she use?

Graphical display of data


Which of the following are the four graphic displays most commonly used in ABA?

Equal interval line graph, cumulative records, bar graph, standard celeration chart


Find the correct match between a type of graphical display and its primary area of application in behavior analysis.

Equal interval line chart – ABA


Choose the phrase that best completes this sentence: On an equal interval line graph, the passage of time should be represented on the

Horizontal Axis (the X-Axis)


For the equal interval line graph, the upper right quadrant of the Cartesian coordinate system represents the….

positive number territory for both the X-axis and the Y-axis.


On an equal interval line graph, a point along the X-axis represents X ; a point along the Y-axis represents Y ?

X= a particular period of time during which a measurement was taken; Y= a quantification of the target behavior


What is the most commonly used format for charting ABA data?

Equal interval line graph


Look at the chart below. What part of the graph is represented by the circled (1)



Look at the chart below. What part of the graph is indicated by (4)?

Phase change line


Look at the chart below. What part of the graph is represented by the circled (3)?

Data point


The horizontal axis on an equal-interval line graph is also called the ___.



In Applied Behavior Analysis, the passage of time is commonly represented in the ___ of an equal-interval line graph.

Horizontal Axis


The different values along the X-axis in various chart types may be used to represent changes in which of the following?

X = the passage of time

Y = different values of the dependent variable

Z = values of different environmental variables

X and Z but no Y


The ordinate is another name for which of the following axes?

The Y-axis


In Applied Behavior Analysis, the vertical axis of an equal-interval line graph is used to represent:

Changes in the dependent variable


Distortions in data displays reduce the effectiveness of visual analysis. Which of the following techniques is NOT used to reduce the likelihood of distortions in a graphical display of behavioral data?

All of these procedures are effective in minimizing data display distortions: Calibrating the relative lengths of the X and Y axes in related to each other, using standard units of time, using appropriate ranges for the Y-axis


What is the recommended ratio for calibration of the X- and Y-axes on an equal-interval line graph in Applied Behavior Analysis?



What type of chart is represented below?

Cumulative record


Which chart demonstrates the most appropriate type of data point markers?


A data path represents the relationship between the X and the Y .

X = Independent variable (IV); Y = Dependent variable (DV)


Condition change lines are:

Dotted lines representing changes in the parameters of an intervention


Look at the chart below. What type of line should be used to indicate a change from “Baseline” to “Self-record”?

Phase change line


What type of label states the response measure that was used to measure the dependent variable (the target behavior)?

Y-axis label


A figure legend:

A concise statement providing enough information to identify the DVs and IVs, and other salient information necessary for visual analysis


Which of the following characteristics of a data path is not a primary consideration when conducting a visual analysis of a set of data?



A level line is

A flat horizontal line through a set of data, across a condition or phase, usually at the average value of that set of data.


The mean value is the _____ value of a set of data, while the median is the _____ of a set of data.

X = Average

Y = Mathematical center between the top value and bottom value in the range of a full set of data

Z = Value of the data point in the middle of a set of data points, ordered by ascending value (or the average value of the two middle points)



What is the mean value and the median value for the following set of data point values?

5, 5, 4, 9, 8, 6, 5

Mean = 6 Median = 5


The following graph represents what kind of trend?

No trend


ook at the following table of data on Bennett’s “pica attempt” behavior. Between Day 4 and Day 5, the first treatment phase was implemented after 4 days of baseline.

In comparison to the baseline phase, does the level in the treatment phase go up, go down or remain the same?

The level is the same between both phases


Looking at the table above, at Bennett’s pica attempts, what kind of trend is evident in the treatment phase?

Decreasing trend

Treatment data, once converted, are 20, 16, 14, 10. This is a clear decreasing trend, without much variability.


A flat line on a cumulative recording indicates…

A zero rate for the dependent variable for as long as the line remains flat


In a bar graph, the horizontal axis typically represents:

Classification variables of some type
