The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
In biostatistics and research methodology, it is important to distinguish between the group of interest (the population) and the subset of that group selected for study (the sample).
Step 2: Detailed Explanation:
Let us define the statistical terms used in this study:
- Population: The complete group of individuals, items, or measurements that the researcher wants to study and make inferences about. In this scenario, because the researcher is interested in the birth weight of all pigs in Assam, the entire group of these pigs represents the target population.
- Sample: A subset of the population selected for actual measurement. It is practically impossible to measure every single pig born in Assam, so the researcher will measure a smaller sample to represent the population.
- Parameter: A numerical characteristic of the population, such as the true mean birth weight of all pigs in Assam. Parameters are typically unknown and must be estimated.
- Statistic: A numerical characteristic calculated from the sample, such as the average birth weight of the measured sample of pigs. This statistic is used to estimate the population parameter.
Since the question refers to the entire group of pigs in Assam, it represents the statistical population.
Step 3: Final Answer:
Therefore, the entire group of pigs in Assam is an example of a population.
