Going specifically by the white book frequency is the same as count, and just refers to a summation of the behavior. Rate is count/time. There are some issues with the frequency/rate distinction, but that's the textbook answer.
What is the Difference Between Frequency, Rate, and Count? Count is a tally of observations, and rate considers the count over time. While textbooks define frequency as a count, behavior analysts almost always use it as a rate.
In statistics, the frequency or absolute frequency of an event is the number of times the observation has occurred/been recorded in an experiment or study. [1]: 12–19 These frequencies are often depicted graphically or tabular form.
From the Glossary: Frequency: A ratio of count per observation time; often expressed as count per standard unit of time (e.g., per minute, per hour, per day) and calculated by dividing the number of responses recorded by the number of standard units of time in which the observations were conducted… (p. 696) What came next surprised me:
Remember, you count frequencies. To find the relative frequency, divide the frequency by the total number of data values. To find the cumulative relative frequency, add all of the previous relative frequencies to the relative frequency for the current row. Answer. 29%; 36%; 77%; 87; quantitative continuous
There are two primary types of frequency counts: absolute frequency and relative frequency. Absolute frequency refers to the actual count of occurrences of each value in the dataset, while relative frequency expresses this count as a proportion of the total number of observations.
Why it matters: Frequency is used when you want to count how many times a behavior is occurring. Behaviors may occur too often or too little and may need to be targeting for intervention. Rate. Definition: A measure of how often a behavior occurs over an amount of time. Rate is like frequency, except with a time component added.
Definitions: If the frequency of the $i$ th bar is $f_i,$ then its relative frequency is $r_i = f_i/n,$ where $n$ is the sample size. Its density is $d_i = r_i/w_i,$ where $w_i$ is its width. Ordinarily, you should make a density histogram only if each bar has the same width.
Count/Frequency: The number of occurrences of a behavior; Rate: The number of occurrences of a behavior per a set amount of time; Celeration: how rate of responding changes over time
Continuous measurement in ABA involves tracking a behavior over a specific time. For instance, counting how many times a child raises their hand in class is continuous. Continuous data is the most accurate way to gather insights into behavior. Data collection is the core of Applied Behavior Analysis (ABA).
