2  What is the survey method and how is it used?  How does sel

3  A method of gathering info using surveys  Surveys --A research technique for acquiring data about people’s attitudes and behaviors  Involves asking questions  In person  Through questionnaires What are some potential problems with the accuracy of surveys?

4  Dishonesty  Not wanting to divulge personal information  Giving only partially true answers  Telling researchers “what they want to hear”  Targeting the wrong group  Survey must represent the target population – the whole group that you want to study or describe  Bias – predisposition to a certain point of view  Volunteer Bias -- people who volunteer to participate in surveys have a different outlook from people who do not volunteer  Willingness to be open  More interested in research

5  Sample -- Targeting a small group (or sample) of a given population  Random Sample – individuals selected by chance from a population group  Stratisfied Sample – drafting a sample so that subgroups are proportionately represented  Large enough samples will be naturally proportionate

6  Results of a survey CANNOT be generalized if the survey does not represent the target population.  Ex. Longer school day survey (senior elective class vs. sophomore biology class)
