CH06 Graphic Displays of Behavioral Data

Question 1

Bar graph (& AKA)

Answer 1

(AKA - Histogram)

1. Used for displaying and COMPARING DISCRETE SETS of data that are NOT RELATED to one another by a common underlying dimension by which the horizontal axis can be scaled
2. Provide a VISUAL SUMMARY of the PERFORMANCE of a participant or group of participants DURING the DIFFERENT conditions of an experiment.

“quick and easy comparisons of performance across participants and/or conditions.”

Question 2

Cumulative record

Answer 2

a) Shows the number of responses on the ordinate against time on the abscissa.
b) number of responses recorded and added to the total number of responses recorded during previous observations (Cumulative).
c) Y-Axis represents the total number of responses recorded since the start of data collection

• developed by Skinner.
• primary means of data collection in EAB (graph)

Question 3

What does it mean to have a steep slope on a Cumulative record?

Answer 3

a) The steeper the slope, the higher the response rate.
b) Relative rates of response

• Overall response rate
• Local response rate

Question 4

Cumulative recorder

Answer 4

Device that enables a subject to actually draw its own graph

Question 5

overall response rate

Answer 5

average rate of response over a given time period or condition of an experiment

Question 6

local response rate

Answer 6

refers to the rate of response during periods of time smaller than that for which an overall rate has been given

Question 7

Semilogarithmic Chart

Answer 7

AKA: Ratio or Multiply-divide charts

One axis is scaled porportionally.

Question 8

Standard Celeration Chart

Answer 8

Charting & analyzing how FREQUENCY of BEHAVIOR CHANGES over time.

the chart utilizes frequency and rate to describe behavior change, and rate and growth of learning across time (i.e., celeration).

Question 9

Scatter plot

Answer 9

Shows the RELATIVE DISTRIBUTION of individual MEASURES in a data set.

Depicts changes in value on one axis correlated with changes in value on the other axis

• Data points are UNCONNECTED.
• PATTERNS SUGGEST certain RELATIONSHIPS

Question 10

Variablility

Answer 10

The EXTENT to which MULTIPLE MEASURES of behavior yield DIFFERENT OUTCOMES

Question 11

level

Answer 11

the value on the vertical axis scale around which a set of behavioral measures converge

Question 12

trend

Answer 12

overall direction taken by a data path

Question 13

Horizontal Axis

Answer 13

X- axis
Abscissa
“Passage of Time”
IV

Question 14

Vertical Axis

Answer 14

Y- axis
Ordinate
“dimension of behavior”
VOY

Question 15

split-middle line of progress

Answer 15

a method of calculating a drawing lines of progress that is more reliable than the freehand method adn much less time consuming

Question 16

data path

Answer 16

represents the level and trend of BX between successive data points

Question 16

line graph

Answer 16

most common graph format for displaying data in ABA

Question 18

visual analysis

Answer 18

a system approach for interpreting the results of behavioral/research and treatment programs

visual inspection of graphed data for variability, level and trend
