Joseph has difficulty in reading. He is very slow. We are interested in increasing his fluency (how fast he reads).
What is the target behavior?
What is the behavioral dimension?

Given a 5th grade reading passage, Joseph will read 97 words per minute across three one minute reading passages.

J will independently follow all the steps in washing hands routine
What behavioral dimension? how often it happens (frequency)What data system? “all the steps” indicates a Task
Analysis or event recording

J had difficulty staying on task even with leisure activities. Mother has requested that we work on getting him to stay engaged for at least 3 minutes so she can have a moment alone when in the house.
What behavioral dimensions should we consider?Duration – how long he stays with the activityFrequency - how many times he stays with the activity for 3 minutes

After choosing a leisure activity, J will engage in that structured activity from for 3 minutes 4 out of 5 opportunities.

Given three different reading materials (e.g, flashcards, books, signs in the community), Gitit will read 50 functional sight words (see list) with 100% accuracy.

When given a task that is new and difficult, Neil will request assistance/help at least once during the activity without engaging in challenging behavior.

Graphing
Summary of raw data into a readable format
A picture says a thousand words
Clear, easy to interpret and everyone on same page
![Page 13: Writing and connecting objectives to data collection](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56649eb35503460f94bba1eb/html5/thumbnails/13.jpg)
Conversion of Data
Need to convert raw data into a more representative number
Frequency data that is collected with different number of opportunities -- percentage
Frequency data when varying amounts of time were available – rate
![Page 14: Writing and connecting objectives to data collection](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56649eb35503460f94bba1eb/html5/thumbnails/14.jpg)
Interval or Time Sampling is reported in terms of number of intervals the behavior occurred or percent intervals the behavior occurred
Duration or Latency is reported in terms of number of seconds, minutes, etc…
![Page 15: Writing and connecting objectives to data collection](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56649eb35503460f94bba1eb/html5/thumbnails/15.jpg)
Calculate the percentage
Divide the number of correct responses by the total number of responses and multiply the result by 100
Number of correct responses
X 100= %
Total number of responses
![Page 16: Writing and connecting objectives to data collection](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56649eb35503460f94bba1eb/html5/thumbnails/16.jpg)
Computing Rate
A rate of correct responding is computed by dividing the correct responses by the time taken for responding:
# correct
Correct Time =
Time
Computing a rate of error may be done by dividing the number of errors by the time:
Errors
Rate of Error =
Time

Line graphs
Data are graphed at the appropriate intersections
![Page 18: Writing and connecting objectives to data collection](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56649eb35503460f94bba1eb/html5/thumbnails/18.jpg)

Cumulative graphs
The number of occurrences are added to the previous session
This approach provides the total number of responses
Graphs must always trend upward
![Page 20: Writing and connecting objectives to data collection](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56649eb35503460f94bba1eb/html5/thumbnails/20.jpg)
Bar graphs or Histograms
Data is plotted using a bar to represent the occurrences of the behavior
![Page 21: Writing and connecting objectives to data collection](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56649eb35503460f94bba1eb/html5/thumbnails/21.jpg)
Permanent Product- Data to Graph
Graphed as a number of items If the number of opportunities is constant
or percentage of items If the number of opportunities varies
![Page 22: Writing and connecting objectives to data collection](https://reader036.vdocuments.mx/reader036/viewer/2022062517/56649eb35503460f94bba1eb/html5/thumbnails/22.jpg)
Summary of Data Conversion Process
Type of Recording Data Conversion
Permanent Product * Report number of occurrences
if both time and opportunities to respond are constant
Event * Report percentage if time is constant (or not of concern) and opportunities vary.
* Report rate if both time (which is of concern) and opportunities vary, OR if time varies and opportunities are constant.
Interval * Report number of intervals if constant
Time Sampling * Report percentage of intervals
during or at the end of which behavior occurred.
Duration * Report number of seconds/minutes/hours
for which the behavior occurred.
Latency * Report number of seconds/minutes/hours
between antecedent stimulus and onset of behavior.
