Using the terms listed below, complete the following:
1. ___________ group receives treatment in an experimental
design.
2. ___________ group does not receive treatment in an
experimental design.
3. A ___________ design has many observations on a single case
or a few subjects.
4. When separate groups of subjects receive different levels of
the independent variable, this is referred to as _____________ design.
5. When all subjects receive all levels of the independent
variable, this is referred to as ____________ design.
6. When the researcher measures a behavior that needs to be
changed and then applies therapy and measures the behavior again, this is referred
to as _____________ design.
7. When the researcher measures a behavior that needs to be

______________ design.
8. When the criterion outcome changes over time this is referred
to as _______________ design.
9. When measuring several behaviors or several people with

referred to as a ______________ design.
10. When subjects are not randomly assigned and not all

1. _____ Two classes of children are studied regarding the
effects of a new teaching method in science. One group received the new method
of instruction, while the other group uses the standard, traditional method of
instruction. Both classes are measures for achievement before and after the
teaching methods.
2. _____ Divide your subjects in half. One group receives
one treatment of the independent variable and the other group receives a
different treatment of the independent variable. Subjects were all told they
were going to see a video of a therapist’s session after which they would rate
the quality of the session. The groups differed in that the subjects in one
group were told that prior evaluations indicated that the therapist was
effective whereas subjects in the other group were told that the evaluations
indicated the therapist was not effective. These different subjects were used
for the two levels of the independent variable: subjects were in either the
“effective therapist” or the “ineffective therapist” condition.
3. _____ All subjects perform at all levels of the independent
variable. Subjects diagnosed as having attention deficit disorder were each
tested on a concentration task after receiving medication. All subjects were
tested four times, once after receiving one of the four doses. Each subject was
tested under eachof the four levels of the independent variable-dose of
medication.
4. _____ A small group is measured for the amount of anxiety
they experience in math class (baseline). They are taught a relaxation method
and measured again to measure anxiety in math class.
5. _____ To study verbal commands in canines, during week 1 the
baseline is recorded for how many times a dog chased a cat. During week 2, dog
was verbally scolded (treatment) when the dog chased the cat, and the chasing
behavior was recorded. During week 3, the chasing behavior was recorded without
the verbal scolding (treatment).
