07. Display + Interpretation of Data Flashcards
Data
Medium with which the behavior analyst works, results in measurement, empirical basis for decision making
Graphs
Visual format for displaying data
3 Purposes for Graphs (CAID)
Communicate data
Assess data
ID/DV (shows how they are related)
5 Types of Graphs (LBCSS)
Line Bar Cumulative Record Scatter Plot Standard Celeration Chart
Equal Interval Graphs
Graphs in which the distance between any 2 consecutive points on both the x-axis and the y-axis is always the same (line, bar, cumulative, scatter plots)
Line Graph
Most common in ABA, use when you want your data to effectively communicate data that can be scaled alone dimension (time)
Condition Label
A label written at the top and parallel to the x-axis that describes the experimental conditions during each phase of research
Data Path
Connects successive data points with a straight line that illustrate trend and level of a behavior
Figure Caption
Concise statement that provides info to identify the independent and dependent variable
Bar Graphs
Use when you want you data to effectively communicate separate sets of data that are not related to each other.
Cumulative Record
Keep adding responses with each observation period, the effects of the independent variable are easy to detect on this graph
Overall Response Rate
An average rule of response over a given time period (dividing the total number of responses by the number of observation periods
Local Response Rate
Rate of response during periods of time smaller than that which an overall response rate has been given (select the time period you wish to collect the data from)
Semilogarithmic Charts
Graphs in which one axis is scaled proportionately, all behavior changes of equal vertical distances on the vertical axis
Standard Celeration Charts
Used for academic and social behaviors where students can self-monitor their performance with the goal to increase correct responses
Scatter Plots
Use to discover temporal distributions of behavior and see grouping of individual data points that may help to identify elusive environmental stimuli.
Ethical Warning: Choosing a Graph
Do not choose a graphing method that skews the data, choose one that has the best representation of the data.
3 Fundamental Properties of Behavior Change (LTV)
Level
Trend
Variability
Mean Level Line
Horizontal line drawn through the data points on the vertical axis equaling the average of mean value of the data.
Median Level Line
Horizontal line drawn through the data points on the vertical axis that shows the most typical performance within a condition
6 Steps to Split Middle Line of Progress (CDMMQS)
Count Divide Mid: Mid Rate Mid: Mid Date Quarter: Quarterly-intersect line of progress Split: Split middle line of progress
