Sampling is essential in cancer research for several reasons:
1. Cost Efficiency: Studying a subset of the population is more cost-effective than studying the entire population. 2. Time Management: Sampling allows researchers to collect and analyze data more quickly. 3. Feasibility: Some populations are too large to study in their entirety; sampling makes research feasible. 4. Accuracy: Proper sampling methods enhance the accuracy and reliability of the study findings. 5. Generalizability: Well-designed sampling methods ensure that the study results can be generalized to the broader population.
