Research on the Net
There are many opportunities to take part in research being conducted on the Internet.
Explore some of the sites where experiments are being conducted. What variables are being
studied? How are the variables operationally defined? Is the researcher using the
experimental or the nonexperiment method? Some of the studies use the nonexperimental
method by asking you to fill out attitude questionnaires, personality measures, and so on.
Others use the experimental method -- will be asked to view or read material and then
record your responses. Some experiments automatically assign participants to conditions;
others ask you to provide a number such as the day of the month you were born; this number
in turn determines the condition in which you will participate.
Research Design Web Page
Bill Trochim has developed a web page on research design that includes both
experimental and quasi-experimental designs. This is an excellent resource.
Research Methods Tutorials
Graduate students in Bill Trochim's Program Evaluation and Research Design class at
Cornell University prepared tutorials for students new to social research methods. I will
be referring you to these in several of the chapter pages. Rather than link you to each of
the individual tutorials, I will simply provide one link to the list of tutorials. I
suspect that the content of Dr. Trochim's tutorials page will expand in subsequent
Tutorials related to Chapter 4 include Correlational Research Designs, Non-experimental
Design, Securing Internal Validity - How to Avoid the Threats, Threats
to Construct Validity, and Validity.
