Final answer:
Micah should use convenience sampling to determine the number of single-parent households in his school district due to the time constraint of one day. This method is quick and utilizes available sources.
Step-by-step explanation:
Micah's task is to determine how many single-parent households are represented in his school district, and he only has one day to do so. Given the time constraint and the need for quick data collection, Micah should use a convenience sampling method. This type of sampling allows for the collection of readily accessible data from individuals who are available and willing to participate. He could utilize school records, conduct a quick survey during school hours, or reach out to parent-teacher associations for information they might already have on hand.
Pulling from statistics, we know that more than one-quarter of U.S. children live in a single-parent household, indicating the potential scale within Micah's district. Also, considering the diversity of family structures, ensuring representation from different grades might reflect a stratification intent, but under the time constraint, limiting factors might force him to prioritize expedience over precision, which again points towards convenience sampling as the best method for his circumstances.
