visual analysis of graph

Question 1

experimental event of interest- intervention or treatment
ex. time out, prompts, act. schedule

Answer 1

independent variable

Question 2

estimates of behavior you are analyzing
-target behavior
-includes measurement
ex. rates of agression, % of unprompted correct tacts

Answer 2

dependent variable

Question 3

-level
-trend
-slope
-magnitude
-variability

Answer 3

within phase patterns

Question 4

immediacy of effect
-overlap

Answer 4

across/between phase patterns

Question 5

average of data within a condition
-allows us to evaluate the central tendency within a particular phase
-calculate the mean and draw a trend line to help visually interpret the effects of treatment if there is not a dramatic change between baseline and treatment conditions

Answer 5

level

Question 6

best fit straight line over the data
-slope and magnitude of the trend
-described as the slope (positive, negative, or flat) and the magnitude (high, medium, low)
-ex. positive high trend

Answer 6

trend

Question 7

upward or downward slant -can be positive, negative, or flat

Answer 7

slope

Question 8

high, medium, low

Answer 8

magnitude

Question 9

the degree to which individual data points deviate from overall trend
-high, medium, or low

Answer 9

variability

Question 10

how quickly the behavior changes after the phase change
-slow or rapid
-rapid change helps show functional relation
-more immediate can have briefer phase

Answer 10

immediacy of effect

Question 11

degree to which adjacent data share similar quantitative values
-more of this limits experimental control
-trend trumps overlap, if there is no overlap but data is trending downward in baseline phase and treatment phase, likely no functional relation- data would have continued to decrease even if no intervention was put into place

Answer 11

overlap
