• Recognize that one of the options presented does not qualify as a sampling technique.

Purpose of Sample Design

• Sample design aims to create a strategy for selecting units from a population to obtain accurate and representative data.
• Effective sample design helps minimize bias and ensures that findings can be generalized to the larger population.

Practical Use of Sampling

• Sampling is used to reduce costs and time associated with data collection.
• It allows researchers to gather insights without surveying an entire population, thus increasing efficiency in research processes.

Primary Source of Data

• A primary source of data is information collected firsthand for a specific research purpose, often through interviews, surveys, or experiments.
• This type of data is original and offers direct evidence pertinent to the research topic.

Purpose of Questionnaire in Sampling

• A questionnaire serves as a tool to gather structured information from respondents during sampling.
• It helps to capture data efficiently, facilitating analysis and interpretation of results while ensuring consistency in responses.
