Q
  1. ) Gives you an immediate picture of an individual’s behavior.
  2. ) Allows you to explore interesting variations in behavior as they are occurring.
  3. ) Acts as a judgmental aid to help you interpret the results of a study or treatment.
  4. ) Acts as a conservative method for determining the significance of behavior change, because a behavior change that is statistically significant may not look impressive on a graph.
  5. ) Allows for an independent judgement and evaluation of the data.

A

Bar Graph

24
Q

Use Bar Graphs When You Want Your Data To:

A

Effectively communicate the following relative quantitative relations:
1. Displaying separate sets of data the ARE NOT related to each another.

25
Q

Developed by Skinner to record data in EAB research in 1957.

  • You keep adding on responses during each observation period to the total number of all previously recorded responses.
  • The y-axis value represents the total number of responses recorded since the very start of data collection.
  • Exception: When the total # of responses exceeds the upper limit of the y-axis scale (in which case the data path resets to zero on the y-axis and begins its rise again).
A

Cumulative Records

26
Q
  • Displays cumulative data.

- Enables a subject to draw his/her own graph.

A

Cumulative Recorder

27
Q

Generally Used for Rate/Frequency data.

- The last data point on this graph is how much an individual has acquired at the current time.

A

Cumulative Record

28
Q

2 Types of Cumulative Record Response Rates:

A
  1. Overall Response Rate

2. Local Response Rate

29
Q

An average rate of response during periods of time smaller than that for which an overall response rate has been given.

  • Same calculation as the overall response rate, but only using a small portion of the data on the graph.
A

Local Response Rate

30
Q

An average rate of response over a given time period, such as during a specific session or phase in a study.

  • Calculated by dividing the total # of responses recorded during the period by the total # of observation periods indicated on the x-axis.
A

Overall Response Rate

31
Q

What relevant quantitative relations are effectively communicated on the cumulative record?

(In other words…..)
-Why would a cumulative record be used rather than a noncumulative graph?

A
  1. The target behavior can be measured in cumulative units.
  2. The target behavior only occurs once per observation period.
  3. The cumulative record shows how rapidly or slowly the target responses are repeated.
  4. The cumulative record can be used as personal feedback.
  5. The effects of the IV are easier to detect on a cumulative record rather than a noncumulative graph.
32
Q

AKA: Ratio Chart; Multiply-Divide Chart
LOGARITHMIC SCALES look at behavior change through PROPORTIONAL or RELATIVE change.
- X-Axis = In equal intervals
- Y-Axis = Scaled LOGARITHMICALLY

Graphs in which 1 axis is scaled proportionally.
All behavior changes of equal proportion are shown by equal vertical distances on the vertical axis.
-Data that is shown as an exponential curve on an equal interval chart is a straight line on a ________ ________.

A

Semilogarithmic Charts

33
Q

A type of SEMILOGARITHMIC CHART.

  • Created by Ogden Lindsley to be used in an ABA educational methodology called Precision Teaching.
  • Academic and social behaviors are charted.
  • Provides a standardized mans of charting and analyzing how frequency of behavior changes over time.
  • The scale goes by multiples (2s, 10s, 100s, etc.)
  • Students self-monitor their progress by recording data that makes a graph that displays the number of items they performed correctly and the number of errors they made within fixed periods of time distributed across the day or week.
  • GOAL: To increase the # of correct answers and decrease the number wrong within the set time.
  • Allows data to be squeezed into progressively tighter and tighter bundles.
A

Standard Celeration Chart

34
Q

What relevant quantitative relations are effectively communicated on the ration chart?

(In other words…….)
-Why Would I Use This?

A

Primarily when your concern is promoting RATE OF RESPONDING.
-Rate of responding is really important because research shows that the more rapid and fluent the rate of correct responding, the more durable the learning.

35
Q

Show relative distribution of individual measures in a data set.

  • Data points are UNCONNECTED.
  • Depict changes in value on 1 axis correlated with changes in value on the other axis.
  • One variable (usually the time of day) is plotted on the y-axis and a second variable (usually days) is plotted on the x-axis.
A

Scatter Plots

36
Q

Use Scatter Plots when you want your data to effectively communicate the following relevant quantitative relations:

A
  1. Temporal distribution (TIME) of the behavior.

2. The grouping of the individual data points may help to identify elusive environmental stimuli.

37
Q

Make sure you choose the method that demonstrates the most ETHICAL and VALID representation of the target behavior.
-Do NOT choose a method that skews the target behavior.

A

Base Decision-Making on Data Displayed in Various Formats

38
Q

Three (3) Fundamental Properties of Behavior Change: LTV

A
  1. Level
  2. Trend
  3. Variability
39
Q

Value on the vertical axis around which a series of data measures converge.

  • A change in ______ is illustrated when the data’s average value changes.
  • An analysis of ________ answers the question, “How much has the behavior changed?”
  • _________ in your data are examined by looking at your data’s mean, median and/or range.
A

Level(s)

40
Q

Horizontal line drawn through the data points on the vertical axis equaling the AVERAGE or MEAN value of the data.

  • Can obscure important variability
  • Adds an easy-to-see summary of average performance.
A

Mean Level Line

41
Q

Horizontal line drawn through the data points on the vertical axis that shows the most typical performance within a condition.
-Better than the mean level line when your data has extreme outliers, either high or low.

A

Median Level Line

42
Q

OVERALL direction taken by a data path

  • The general direction and rate of increase or decrease in which data move over time.

  2. Degree: Gradual or steep
  3. Extent of variability of data points around the _____.
A

Trend

43
Q

LINE OF PROGRESS: A straight line drawn through the data to show the trend.

AKA: Split-Middle Line of Progress

A

Trend Line

44
Q
  1. Freehand (not very accurate)
  2. Mathematical formula called, the Ordinary Least-Squares Linear Regression Equation (time-consuming and complicated)
  3. Split-Middle Line of Progress (Best)
A

How Do We Draw Trend Lines?

45
Q
  1. Count (how many data points are on the graph)
  2. Divide (draw a vertical line and divide the number of data points in half; left & right equally)
  3. Mid-Rate (find middle point up/down; mid value for the y-axis; if there are even #’s, use the mean of the two middle-most points)
  4. Mid-Date ( For each half of the data, find the middle points, left to right)
  5. Quarterly-Intersect Line of Progress (Connect the 2 mid-date & mid-rate points of intersection)
  6. Split Middle line of Progress (Shift the quarterly-intersect line up or down; keep it parallel to itself so that an equal # of data points fall above or below it.
A

Six (6) Steps To A Split-Middle Line of Progress

46
Q
  • The extent to which data “bounce around” on the graph.
  • An analysis of __________ answers the question, “How consistent is the change that is taking place?”
  • Frequency and degree to which multiple measures of behavior yield different outcomes.

High degree of _________ = Little to no control over the factors influencing behavior.

A

Variability

Q

Examining data within each condition, determine the level, trend and/or variability in each condition.
