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.
