Chapter 2 Research Methods Please fill in your slides as we proceed

Research Design A detailed plan or method for obtaining data scientifically You need to choose the design carefully to get the best results

Experiments An artificially created controlled situation which allows the researcher to manipulate variables Experimental Group – given the independent variable Control Group – is NOT given the independent variable

The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded. Review: Independent and Dependent Variables

There are many different ways to gather information:  Participant Observation  Naturalistic Observation  Survey  Interview  Questionnaire  Secondary Analysis

Observations Collecting of information through either: 1. Participant observation 2. Naturalistic observation

Participant Observation The researcher joins a group for a period of time to understand how it works

Naturalistic Observation The researcher watches a group without interfering recording their natural behavior Disadvantages Can be time consuming and expensive. Does not allow for scientific control of variables. Experimenters cannot control extraneous variables. Subjects may be aware of the observer and may act differently as a result.

Hawthorne Effect Subjects of a research experiment act differently than normal because they know they are being observed

Survey A study, generally in the form of an interview or questionnaire Provides information on how people think and act Disadvantages: Can be affected by an unrepresentative sample or poor questions. Participants can affect the outcome. Some participants try to please the researcher, lie to make themselves look better, or have mistaken memories.

Advantages and Disadvantages

Interview A verbal question and answer session between two or more people

Advantages and Disadvantages

Questionnaire A set of questions asked with the intent of finding out opinions, interests, and thoughts

Advantages and Disadvantages

Secondary Analysis Research that makes use of publicly accessible information and data

Which method do you think is best? Why?  Participant Observation  Naturalistic Observation  Survey  Interview  Questionnaire  Secondary Analysis

Advantages and Disadvantages
