Which of the following is a type of CONTINUOUS data collection method?

• A. Whole Interval
• B. Frequency
• C. Counting
• D. Single Interval

Answer: (B)

Continuous data collection means recording behavior as it happens, capturing each instance and often turning that into a rate over the observation period. Tracking the number of times the behavior occurs—frequency—provides a continuous tally of occurrences, yielding a precise measure you can convert to rate per unit of time. Whole Interval and Single Interval are interval-based methods; they’re discontinuous because they only tell you whether the behavior occurred during a specific interval, not every instance across the whole session, which hides timing details. Counting is essentially another way to describe frequency data, but the established continuous measure here is frequency, making it the best answer.
