which is correct analysis?
an initial high rate, followed by no responding, followed by a variable rate
Reviewing the file for Diana, a new client who licks her hand, you find a graph from her previous placement. You notice that the activity associated with the highest local rate of licks was her
20-29 Coloring In a cumulative record, the highest local rate will be seen as the steepest section of the line. The steepest spots are where she had the highest rate of licking (she was licking the most times per minute). Notice that she did a fast burst of licking and then slowed down in 20-29. Something else may have changed at 24, even if the activity did not change until 30. pg. 134
Of the options listed, which activty is associated with the local rate that varies the most? 21-29 coloring 0-9 Ignore 50-60 Play 30-39 DTT
21-29 Coloring In the coloring activity their licking was very fast (highest slopes/ highest rate) from Minute 20 to 22, but then they dramatically slowed until end of the interval.We don't say why they suddenly started licking more and the less, but you can see their record disinctly turn up at 20 and then flatten later. Remember that their line rises e/a time they lick and the faster they lick, the steeper it rises. Clinically, this segment should be investigated to see if s/g could be identified that triggered the licking. pg. 134-136

Celeration charts, cumulative records, and other time-series graphs of behavior a. may reveal underlying cyclical changes in bx that otherwise wouldn't be recognized as part of a pattern b. reveal the underlying cyclical nature of bx by eliminating misleading external variability c. bypass the inherent chaotic variability of uncontrolled variables to reveal orderly relations d. function primarily to avoid the use of group (inferential) statistical analyses as a source of scientific information
May reveal underlying cyclical changes in bx that otherwise wouldn't be recognized as part of a pattern. The way data are graphed does not gurantee that orderly relations will emerge.
Average level is the
Mean of the values of the dependent variable
What type of graph is this? a. semi-log b. equal-interval c. bar d. cumulative record
Semi- log The Y-axis is a log scale, in w/c equal distances on the graph are equal ratios (the multiply distance is proportional) so going from 1 to 3 is the smae distance as from 10 to 30 or any other tripling, while the x-axis is equal interval. With one log scale and one equal-interval scale, the graph is semi-log. You can see quickly that it's not a cumulative graph (in w/c the daily # is added to the sum of all previous #'s ) b/ both Day 7 and Day 13 are below the previous data point. pg. 136-139
Which best describes the graph?
a high, stable level of responding followed by a low stable level of responding in the same phase
To find out if you get better performance on the CBA learning module series in the mornings or in evenings, you could use an alternating treatments design and plot your correct and incorrect answer rates using a. a bar graph w/ one bar for correct rate and one for incorrect rate in each condition b. 2 pie charts, one for e/a condition c. a semi-logarithmic plot (Celeration Chart) or other time series line graph d. all above
a semi-logarithmic plot (Celeration Chart) or other time series line graph
Which is the correct analysis?
a steady rate of responding Points on a cumulative graph are the sum of the value of the current point. When data recording has reached the top of the ordinate, the next point reverts to the bottom of the ordinate pg. 134
given appropriate permissions, a way for the BACB to see if ppl who practice the CBA learning module series (LMS) to fluency get higher scores on the BCBA exam would be to a. calculate the correlation coefficient of the percent LMS fluency to the BCBA scores for a group b. plot people's BCBA score on the y-axis and their corresponding % LMS fluency on the x-axis of a graph c. plot people's BCBA scores on the x-axis and their corresponding % LMS fluency on the y axis of a graph d. all above
all of above correct
The goal of designing a single subject graph in ABA is to a. allow the data to most clearly reveal the extent to w/c the dependent and independent variables are related b. convince the audience that change in the independent variable was followed with a major change in the dependent variable c. convince the audience that a change in the dependent variable was followed by a major change in the independent variable
allow the data to most clearly reveal the extent to w/c the dependent and independent variables are related
Which is the correct analysis?
an initial high rate, followed by no responding, followed by a variable rate
What type of graph is this? a. bar b. equal-interval c. cumulative record d. semi-log
b. equal-interval On both axes the additive distances are equal ( the distance on the graph from 10 to 20 is equal to the distance from 80 to 90 or any other 2 points that are 10 #'s apart) so this is an equal-interval graph. It's not a cumulative graph, in which the daily # is added to the sum of all previous #'s , both day 7 and day 13 are below the previous data point .

by convention in ABA, the DV is plotted on the_______________ of ABA line graphs.
by convention in ABA, the DV is plotted on the y axis vertical of ABA line graphs. Time or the IV is plotted on the X axis horizontal
B.F. Skinner invented a recording and graphing system for rate data called the
cumulative record
Trend is the
direction of the data path
Which best describes the graph?
high, stable responding followed by a decreasing trend in the second phase
Which best describes the graph?
high, variable responding followed by low, stable responding in the same phase
A time series graph (equal-interval or semi-logarithmic) of your bx a. illustrates the story of what happened and how your bx changed b. illustrates the qualitative aspects of your bx c. can display levels and trends in your bx in 2-D, but require an additional axis (3-D) to have any display of variability
illustrates the story of what happened and how your bx changed
Average level is
indicated with a horizontal line
Level
is the central tendency of the data along the vertical axis
A defining property of a time-series graph (like successive minutes or successive days) that makes it most useful in ABA work is that
it shows how bx changes over the passage of equal intervals of time
Trend line is the
line of progress
Tantrum data reveal the following counts by shift for a person with developmental disabilities: A new bx reduction plan should start with
looking for what is different on the days that tantrums are reported Use a descriptive analysis (ABC, scatterplot, eco-behavioral assessment) to determine what follows and precedes tantrums and what motivating operations are occurring. Physical antecedents may include reactions to foods and other allergies and a physician referral is advised if these are suspected. Variables may include the presence of certain ppl or specific scheduled activities.
which best describes the graph?
low, variable responding followed by low, stable responding in the same phase
which is the correct analysis?
no responding, followed by an increasing rate, then a high rate, followed by no responding A flat line means no responding. A steep line means rapid responding. B/ the data are cumulative, the data path on acumulative graph corresponds to the rate of the bx,fluctuating b/w steep when the rate is high and flat when no bx is occuring
Which is the correct analysis?
not a cumulative graph Points on a cumulative graph are the sum of the value of the previous point plust the value of the current point. Therefore, there is never a decreasing trend.
Given appropriate permissions, a way for the BACB to see if ppl who practice the CBA learning module seies (LMS) to fluency get higher scores on the BCBA exam would be to a. plot the % LMS fluency on a standard celeration chart b. plot ppl's bcba score on the y-axis and their corresponding lms percentage correct on the x-axis of a graph c. plot ppl's BCBA score on the x-axis and their corresponding % LMS fluency on the y-axis of a graph d. all above

In ABA, quantitative and qualitative msmt of behavioral variables are both discussed in that a. ABA research explicitly rejects qualitative msmt in favor of quantitative msrmt . b. quantitative msrs establish distinct classes of a phenomena, e/a of w/c can reliably be discriminated from others, and qualitative msrs are all numeric c. both are defined by distinct classes of membership for whom reliable and valid definitions have been supported by research d. qualitative refers to how you know the class or identity of what you are counting while quantitative refers to how many you count in that class
qualitative refers to how you know the class or identity of what you are counting while quantitative refers to how many you count in that class
On a cumulative record or graph, the higher the response rate, the
steeper the slope of the graph
If a cumulative record of John's math worksheet problems is smooth,
the fact that the tech's cell phone rang while john was working shows that his performance is stable even when there is a minor distraction
A defining property of the cumulative record or graph that makes it most useful is that
the resultant slope of the line drawn is proportional to the rate of responding
Reviewing the rates of SIB shown on the two graphs shown below you see that a. Arney and Bill have apprxmt the same level of SIB b. there is insufficient info for a comparison c. Arney's SIB data shows less variability than Bill's d. Bill has higher levels of SIB than Arney
there is insufficient info for a comparison These 2 graphs actually use the same #'s- just the layout and the units are different. However, since you don't know how long a "session" is for Bill (minutes? hours? days?), you can't really determine Bill's level of SIB from his graph. Bill's SIB may actually be more, less, or the same as Arney's. That is, if 1 session= 1 day for Bill, then Bill has 6-14 episodes per day, while Arney has 6-14 episodes per hr. However, if a "session" is 30 mins for Bill, then he is emitting 12-28 per hr., or twice the SIB of Arney. pg. 145-152
A trend line on a like graph goes through a series of data points representing an individual's bx over time. If we make no change in the environment,
we make the assumption that extending the line beyond the existing data will predict the individual's bx in the future.
