Sampling is a practical approach in data analysis due to its efficiency in terms of time, cost, and complexity. Analyzing an entire population, especially in large datasets, is often impractical or impossible due to resource constraints. By using a representative sample, analysts can gather meaningful insights and make accurate inferences about the larger population without the exhaustive effort required to analyze every individual item. This efficiency is particularly crucial when dealing with extensive databases or real-time data where analyzing the full dataset is unnecessary. Sampling thus allows analysts to balance accuracy with feasibility, reducing the scope of data while retaining reliable results. The other options are incorrect because: • Option 1 is misleading, as sampling does not inherently provide more detail than full population analysis; rather, it offers an approximation. • Option 2 is incorrect since bias can occur in sampling; careful sample design helps mitigate it, but sampling does not inherently prevent bias. • Option 4 is inaccurate; rare events might actually be underrepresented in sampling, depending on the sample type and size. • Option 5 is false; sampling introduces sampling error, and conclusions are approximate, not absolute, for the entire population.
