Equal-Interval Line Graph C-10, C-11 Flashcards
Data
quantification of a measurable phenomena
Systematic visual examination of graphed data
visual analysis
Graph:
Visual representation of relation between
series of measurements and relevant variable
Equal-interval line graph:
Displays
data points connected by lines showing relation between variables
X-axis:
Where is it?
horizontal axis on a line graph
X-axis:
Typcially represents
passage of time
Y-axis:
Where is it?
verticle axis on a line graph
X-axis:
Typcially represents
range of values of the dependent variable
Data Point: Represents specific relation between:
2 variables measured along each axis line
Data path
series of straight lines connecting successive data points
Data paths generally break between
phases or conditions
Y-axis label specifies the
type of response measure used to quantify the target behavior
X-axis label specifies
time periods shown by each successive data point
Phase/Condition label
title indicating environmental arrangement
Phase/Condition line
verticle line indicating planned or unplanned environmental change
Figure Legend
Concise statement providing info about graph
Descriptive statistic:
Values that
summarize (describe) a data set
Mean
average value of a data set
Median
middle data point in ordered data set
Mode
data value that occurs most often in a data set
Level
mean value of a set of data points
Trend
direction of data path through a set of data
Variability
amount of divergence between measures of behavior
Visual analysis of graphed data:
Step 1
evaluation the general characteristics of the entire data display
Visual analysis of graphed data:
Step 2
inspect and analyze specific data
3 types of data display
text, tables, and graphs
4 types of graphs in ABA:
Equal-interval line graph
Bar graph
Semilogarithmic graph
Cumulative Record
Abscissa
x-axis
Ordinate
y-axis
Mean, median, and mode are
3 measures of central tendency
