Control Group Design
• Group that gets the “0” variable
o Within Subject design:
Referred to as “control condition”
Expectations may act as a confounding variable if control group is led to
believe that they are different than the other groups.
All groups should be equal except for the independent variable.
Instead of only giving an alcoholic drink of 2oz and 4oz, and no drink to the
0oz, ALL groups should have something to drink. Confounding variable is
ruled out by using that 0oz drink for the control group as a PLACEBO.
1. Placebo Control Group- purpose is to control for expectation effects that
otherwise might be acting as a confounding variable.
2. Waiting List Control Group
• a control group where subjects are not yet receiving treatments or
therapy, but eventually will, after the study is over.
• Other group receives the therapy immediately; or a new type of
therapy vs. an old therapy.
3. Yoked Control Group
• used when subjects in the experimental group participate for
varying amounts of time or experience different things in the study.
Each subject in the control group is yoked (matched) to a subject in the experimental group so that, for the groups as a whole, the time
and type of event are kept constant.
• you are trying to control for procedure.

Research report = journal article = empirical report
2. Abstract (100-120 words)- it is a summary
o Should mention:
o Literature search
o Educating the reader of background research and information
o Prove to the person that what you are doing has not been
o Narrow it down to your hypotheses (NOTE: plural)
o Smith (1998) form
o Participants (where
