Problem:
A researcher is conducting a poll to determine which candidate will win the next political election (Candidate Brown vs. Candidate Jones). To ?nd out, the researcher calls 500 individuals, informs them that candidate Jones is an accused child molester, then asks which person they will vote for.
- The sample is too small.
- The measurement approach is biased (internal validity)
- The sample is biased (external validity)
- The poll is utilizing fraudulent data
