D078 BCBA Task EXAM | Questions and
Answers | 100% Correct (Latest Update 2025 /
2026)
1. What is single-subject experimental design ANS When a single
subject serves as both control and experimental group, behavior is
measured repeatedly, yielding individualized results, also called single
case design, intrasubject design, within-subject design, or repeated-
measures design, typically involving 4–8 subjects
2. What is correlational analysis ANS Measures and compares the
amount of behavior under at least two environmental conditions or
treatment values without manipulating those conditions
3. What is descriptive analysis ANS Measures the amount of behavior
under one environmental condition or treatment variable without
manipulating that condition
4. What is experimental analysis ANS Manipulates the independent
variable to observe changes in the dependent variable
1
, 5. What is hypothetical analysis ANS A reasoned guess that two events
are related, an assumption
6. What does experimental control require ANS Measurement of target
behavior, repeated presentation of the independent variable, control of
extraneous variables
7. What is the dependent variable ANS The target behavior and the
dimension being measured, e.g., rate of greetings, number of math
problems completed correctly in a minute, frequency of hand biting
8. What is the independent variable ANS The arrangement of events by
the experimenter to exert control over target behavior
9. What is a functional relationship ANS Demonstrated when there is a
significant change in level and/or trend, a few outliers may not
compromise experimental control
10. What is direct replication ANS An experiment duplicating exactly
the conditions of an earlier experiment
