Key Concepts

Sampling Bias

Sampling bias occurs when the individuals sampled are not representative of the population the researcher intends to study. In this case, Marco's use of students from a university library means that his sample likely reflects the opinions of a specific subset of the population, which may differ significantly from the general electorate.

Non-representative Sample

A non-representative sample fails to capture the diversity of opinions present in the entire population of voters. Since university students might have different preferences, backgrounds, or political leanings compared to the broader community, conclusions drawn from this group might not accurately predict the outcome of the election.
