Research Procedures
Step 1: Review
the population being used for the study.
Step
2:
Select and obtain an appropriate sampling frame for the study,
such as a list of local businesses, a list of an organization's
volunteers, or a list of students enrolled in a consumer behavior
course.
Step
3: Determine
the sampling method to be used. Use a probability sample if
time and resources allow the planning and estimating of statistical
sampling procedures or if conclusive data are desired. Use a
non-probability sample if time and resources are limited and
an exploratory study is being conducted.
Step 4: Determine the sample size. For probability
samples, calculate the sample size based on confidence level,
population standard deviation, and acceptable tolerance of allowable
error. For non-probability samples, select a sample size based
on past studies, judgment of the researcher, or available time
and resources.
Step 5: Determine the participant
selection process based on your sampling method. Propose actions
for attaining the desired sample size and for handling non-respondents.
