C. Measurement, Data Display, and Interpretation 

​

C-1 Establish operational definitions of behavior. 

C-2 Distinguish among direct, indirect, and product measures of behavior. 

C-3 Measure occurrence (e.g., count, frequency, rate, percentage). 

C-4 Measure temporal dimensions of behavior (e.g., duration, latency, interresponse time). 

C-5 Measure form and strength of behavior (e.g., topography, magnitude).

C-6 Measure trials to criterion. 

C-7 Design and implement sampling procedures (i.e., interval recording, time sampling). 

C-8 Evaluate the validity and reliability of measurement procedures. 

C-9 Select a measurement system to obtain representative data given the dimensions of behavior and the logistics of observing and recording. 

C-10 Graph data to communicate relevant quantitative relations (e.g., equal-interval graphs, bar graphs, cumulative records). 

C-11 Interpret graphed data.
