This page is designed to aid you in assessing the validity of information you will find on the
World Wide Web through the use of the Web Validity Wizard (VWiz).
The VWiz will walk you through a variety of steps. You will be asked a series of questions,
all of which you must respond to, even if the answer is "I don't know." There are a wide variety
of questions, and sometimes the answers will require some effort. You might want to print out a copy of the questionnaire to consider before actually proceeding.
The VWiz will result in three estimate coefficients, each of which will be a value somewhere
between zero and one. The three estimates measure internal validity, external validity, and
overall validity. If either of your internal or external validity coefficients is low, then your
overall validity will be low, and there is a good chance the source is not very valid. If both of
your internal and external validity coefficients are high, then your overall validity will be high,
and chances are that the Web source is a good one.
Please Respond to Each Item.

the Content of the document.
