Study Notes

Types of Data Collection

Three main methods: Frequency, Interval, Duration.
Choice of method depends on required information and available resources.

Event Recording

Involves counting occurrences of a behavior.
Requires tallying each instance during a specified observation period, like a 30-minute session.
Aims to modify behaviors by providing clear start and end points for observation.

Interval Recording

Suitable for continuously occurring behaviors, categorized into short time intervals (10 seconds to 1 minute).
Data recorded as "+" if behavior occurs and "-" if it does not.

Duration Recording

Measures the total length of time a student engages in a specific behavior.
Timing starts when the behavior begins and stops once it finishes.

Time Sampling

Involves observing the student only at designated time intervals.
Behavior is recorded at the end of each interval, noting if it occurs at that moment.

Latency Recording

Focuses on measuring the time taken to initiate a behavior after a directive is given.
Requires noting when the instruction is provided and when the student starts the response.

Baseline Data

Collected prior to any interventions to track behavior frequency and establish a comparison point.

Purpose of Data Collection on Behavior

Helps identify patterns and reasons behind behavior occurrences.
Assists in evaluating the effectiveness of support programs.

Importance of Graphing Data

Graphs visually represent behavior changes over time, indicating whether behaviors are improving, worsening, or remaining constant.

Line Graph

Utilizes points connected by lines to show trends in behavior over time.

Bar Graph

Displays data using bars to compare different categories or time periods.

Line Graph Components

Bottom X Axis: Represents the time period during which data was collected.
Side Y Axis: Summarizes behavior frequency or count of occurrences.
Data Points: Each represents behavior summary, connected to illustrate changes over time.

Graphing Reasons

Facilitates understanding of behavior frequency trends over time and provides clear visual information on target behaviors.

Basic Graphing Rule

At least three data points are necessary to establish a trend in behavior increase or decrease.

Graphing Data Conversion

Raw data must be converted into usable formats like percentages, number of correct responses, or rates.

Percentage Calculation

Formula: Correct responses ÷ Total responses × 100.
Example: 20 correct out of 40 possible = 50% correct.

Rate Calculation

Formula: Correct responses ÷ Response time.
Example: 20 correct responses in 30 minutes = 0.7 correct/minute.

Baseline Data Collection

Measure behavior of interest several times before intervention begins.
Essential for evaluating treatment needs and setting reasonable objectives.

Reasons for Baseline Data

To identify a need for treatment.
To compare against future progress during interventions.
To establish realistic treatment goals.

Baseline Data Variability

Human behavior often exhibits variability; multiple data points capture this characteristic.

Baseline Patterns

Consistent results for recorded behavior indicate a stable pattern, such as a constant rate of specific behaviors occurring.
