Surveys
• Be careful of the wording!
One of the most startling set of survey results were reported in 1992 when 1 out of 5 Americans doubted that the Holocaust had occurred, while another 12% said they were not sure.
The question posed by the respected research firm Roper Starch : “As you know, the term Holocaust usually refers to the killing of millions of Jews in Nazi death camps during World War II. Does it seem possible or does it seem impossible to you that the Nazi extermination of the Jews never happened?”

Surveys
When a Gallup poll asked respondents the much simpler, “Do you doubt that the Holocaust happened, or not?” 9 % said they doubted the truth of the holocaust, and another 4% said they were unsure.

Surveys
• Random sampling is IMPORTANT!
• Make sure that everyone in your population has an equal chance of participating

Naturalistic observation

Correlation
• Describing behavior is a first step toward predicting it.

Correlation
Activity: Practice Problems
![Page 14: How Do Psychologists Ask and Answer Questions?. Operationalism Replication](https://reader031.vdocuments.mx/reader031/viewer/2022032205/56649e5f5503460f94b58e46/html5/thumbnails/14.jpg)
Important Point!
• A correlation may suggest causation but does NOT prove causation!
• Discussion: “Eating ice cream increases the murder rate.”
• Activity: Forming Impressions of Others

Experimental Methods
• Researchers can determine cause and effect with an experiment that utilizes random assignment.
– Manipulate the factor of interest
– Hold constant (control) other factors

Validity Within an Experiment
• Internal Validity: how confidently one can conclude that the change in the dependent variable was produced solely by the independent variable and not extraneous ones
• External Validity: extent to which a study's results can be generalized/applied to other people or settings
