Suggested Answer: B Vote an answer

* Systematic sampling is a probability sampling method where researchers select members of the population at a regular interval (or k) determined in advance12.
* In this case, the healthcare quality professional is selecting every other patient admitted to the emergency room, which means the interval k is 2.
* This sampling technique is simpler and more straightforward than random sampling, and can cover a wide study area13.
* However, it also introduces some potential biases, such as over- or under-representation of certain patterns, depending on the order of the population13.
* Therefore, systematic sampling should only be used when the population order is random or random- like, such as alphabetical or numerical12.
* If the population order is cyclic or periodic, such as alternating between genders or age groups, systematic sampling may result in a non-representative sample12.
