ABA Data Collection, graphing
Basic rule for making sense out of data on a graph - There must be at least 3 data points to tell if
there is a trend for the behavior to increase or decrease.
One of the most important reasons we use graphs is to - tell if a behavior is occurring more or less
often or not changing over time.
Latency Recording - Focuses on time rather than frequency.
How long a student takes to begin performing a particular behaviour once it has been requested.
Note when you give the student a directive and when the student begins the response
3 main types of data collection - 1. Frequency.
2. Interval.
3. Duration.
The type you use must be based on
- the information that needs to be collected.
- Can be collected with resources on hand.
Event Recording - Counting the number of times a behaviour occurs.
A tally is made each time the student engages in the target behaviour.
This count is made within a specified time such as 30 minute session.
used to increase or decrease a behaviour.
Must have a clear start and ending.
Interval Recording - used for behaviours that appear continuos.
Break the observation period into short intervals of time. usually 10 seconds to 1 minute.
Record + if behaviour occurs.
Record - if behaviour does not occur during the interval
, Duration Recording - Length of time the student engages in the behaviour.
Start the stopwatch when the student begins the behaviour and stop when it is completed.
Time sampling - Set up usually in minutes.
the observer looks at the student ONLY at the end of the interval and records whether the behaviour is
occurring at he instant.
.
Baseline data - Initial data is collected without any interventions.
You are just keeping track of how many times the behaviour is occurring.
Why we collect data on behaviour - - data help us understand why certain behaviours occur and
do not occur.
- Data allows us to determine if our support programs are working or not,
The best way to make sense out of the data collected on behaviour of people we support is to -
Graph the data.
Graphs give us a way to see how behaviour is changing over time and whether the behaviour is getting
better, worse, or not changing.
Line graph -
Bar Graph -
Parts of a line graph.
Bottom X axis - Bottom X axis shows period of time in which the data was collected
