Scenario: A researcher is interested in estimating the proportion of the population on a
particular construct characteristic within the researcher's area of scholarly interest [Fill
in with something that would be appropriate for your area of research interest]. A
measurement instrument has been created that can be used to categorize respondents as
either demonstrating the characteristic, or not. The researcher has obtained a population
frame to draw a sample from. The frame contains 3400 records.
Question: How large of a random sample is needed to estimate the population
proportion to within plus or minus 2% and be 95% sure the estimate is correct? Do
NOT take nonresponse into account. Remember, this is a sample size estimate, which
means you should round UP for your final answer.
