Question

Why do some researchers use a sample rather than the entire population in some studies

A) Cost-effectiveness
B) Increased accuracy
C) Time efficiency
D) Ethical considerations

Answer 1

Researchers use a sample rather than the entire population in some studies due to cost-effectiveness, increased accuracy, time efficiency, and ethical considerations.

Step-by-step explanation:

Researchers use a sample rather than the entire population in some studies for several reasons:

1. Cost-effectiveness: Analyzing an entire population can be time-consuming and expensive. By using a sample, researchers can collect data more efficiently and at a lower cost.
2. Increased accuracy: With proper sampling techniques, a sample can accurately represent the characteristics and behaviors of the entire population. This allows researchers to make valid inferences about the population.
3. Time efficiency: Conducting research on an entire population may not be practical due to time constraints. Sampling allows researchers to gather data within a reasonable timeframe.
4. Ethical considerations: Some studies involve sensitive topics or interventions that could potentially harm the entire population. Using a sample allows researchers to minimize risks and protect the well-being of participants.
