Sample is a part or subgroup of the given population.

A sample is indeed a part or subgroup of the given population. When conducting research or surveys, it is often not feasible or practical to collect data from the entire population. Instead, a smaller representative group, known as a sample, is selected to gather information and make inferences about the larger population. This allows researchers to draw conclusions and make generalizations about the population based on the characteristics and behaviors observed within the sample. Therefore, the statement that a sample is a part or subgroup of the given population is true.
