APFIVE Systematic Sampling and Periodicity Bias
What potential bias might arise when using systematic random sampling to study customer satisfaction at a store that experiences weekly sales cycles?

B
Periodicity bias, where the sampling interval aligns with the weekly sales cycle, potentially over-representing certain days of the week.
C
Selection bias, where customers are chosen based on their likelihood to provide positive feedback.
D
Sampling frame bias, where the list of customers used for sampling is incomplete or outdated.
