A complete list of sample unit is called?
A. Sampling error
B. Sample unit
C. Sample frame
D. None of these
Answer (2)
The correct answer to the question is C. Sample frame, which is a complete list of sample units suitable for research. A sample frame is vital because it helps researchers select a representative sample for accurate analysis. It serves as a foundation for bias-free and reliable research findings.

The question is about identifying what a complete list of sample units is called within the context of statistical sampling. The correct answer to this multiple-choice question is c. Sample frame .
In statistical terms, a sample frame is a comprehensive list or database that includes all the elements or units from which a sample is actually drawn. These units are known as sampling units. Here’s a breakdown of the key concepts involved:
Population : This refers to the entire group of individuals or instances about whom the data is desired. For example, all students in a school.
Sampling Unit : This is an individual member or element from the population that can be selected as part of a sample. In the student example, a sampling unit could be a single student.
Sample Frame : This is a complete list of all the sampling units available from the population from which a sample can be selected. The sample frame should ideally include every member of the population to ensure accuracy.
Sampling Error : This is the error that arises when the sample selected does not perfectly represent the population due to chance. It is not a list or collection of units, therefore not the correct answer for this question.
In summary, the sample frame is crucial in ensuring that a sample is representative of the entire population. If the sample frame is incomplete or biased, it can lead to inaccurate results.
