Using your research problem and the refined question you developed in Week 4, develop two sampling structures: probability and nonprobability. Probability sampling involves random selection, where each case in the population has a known chance of being chosen, enabling statistical generalization. Non-probability sampling does not involve random selection, making it impossible to calculate the likelihood of any case being included, which may lead to higher chances of missing certain cases.

Describe who would be included in each sample and how each would be selected. Explain the utility of random sampling methods in providing unbiased estimates and enhancing precision, while also noting their potential downsides, such as being time-consuming and requiring less prior knowledge of the population. Conversely, highlight the advantages of non-probability sampling, such as being economical and quick, especially useful for exploratory research, but also acknowledge its limitations, including potential biases and lack of reliability.

Evaluate the strengths and limitations of each sampling approach, paying particular attention to how each aligns with your specific research aims. Consider the trade-offs involved in choosing between the two methods, emphasizing efficiency, accuracy, and potential biases.
