Populations cannot be stratified and samples can.
The Correct Answer is C
A. Developing eligibility criteria for populations is not typically a reason for using samples instead of populations.
B. While data from a sample can sometimes be more manageable and easier to analyze, it's not accurate to say they are inherently more accurate than data from a population.
C. Working with samples is often more practical, economical, and efficient than attempting to gather data from an entire population, especially in large or geographically dispersed populations.
D. Populations can be stratified, but sampling allows researchers to select specific subgroups of interest from a population, making it easier to study specific characteristics or variables.
