Psychology 375: Methods of Study and Research
In the field of I/O Psychology, different techniques are used to collect and
interpret the data in a study. Researchers perform field studies
when there is a significant difference between expected performance and
actual performance on a particular task or job.
Problem Recognition
The first step is to identify the problem. Techniques such as a
needs assessment are used to highlight the problem. Once the
problem has been identified, there are two main categories of research
methods:
- The Experimental Method
- This method is used when the experiment can be performed in either
a field or laboratory setting. In this method, hypotheses that
might describe the predicted behavior are used. Descriptive
statistics from the experiment are analyzed to determine whether or not
the hypothesis is correct.
- The Observational Method
- This method is used when laboratory experimentation is not
possible or if too little is known about the behavior in question.
Like the experimental method, descriptive statistics are used to
analyze the data and identify relationships between variables.
