Discontinuous Measurement

Types of Discontinuous Measurement

100

This measurement requires the behavior to occur for the entire interval

Whole Interval Recording

200

This measurement records whether the behavior occurred at any point of the interval

Partial Interval Recording

300

This measurement represents behavior through a "snapshot"

Momentary Time Sampling

Using Discontinuous Measurement

100

This measurement is best used for behaviors we want to increase

Whole Interval Recording

200

This measurement is best used for behaviors such as Off-Task Behavior or Aggression

Partial Interval Recording

300

This measurement is best used when monitoring of the entire interval is limited

Momentary Time Sampling

Interpreting Data & Graphing

100

Interval data is graphed as...

Percentage

200

Behavior was present for 3 out of 10 intervals. How is this presented on a graph?

30%

300

The Y-axis on a graph represents...

% of intervals with behavior present

Sampling Bias & Common Errors

100

This measurement underestimates behavior

Whole Interval Recording or MTS

200

This measurement overestimates behavior

Partial Interval Recording or MTS

300

During MTS, the RBT records 'Yes' after the behavior occurred halfway through the interval. Was this implemented correctly?

No (recording happens at the end of the interval)
