Sampling is a fundamental technique in data analysis because it allows analysts to work with a subset of data that represents the entire population, significantly reducing the time, cost, and complexity associated with collecting and analyzing complete datasets. Instead of gathering data from every single individual in a large population, which could be prohibitively expensive and time-consuming, analysts can collect a smaller, manageable sample. When properly done, this sample can provide accurate insights into the larger population, making it a powerful tool for inference and decision-making. Sampling is especially useful when data collection for the entire population is impractical or impossible, or when quick results are needed. The other options are incorrect because: • Option 1 (Accurate representation) is not always guaranteed by sampling. Sampling can provide a representative estimate but may still involve some level of error or bias. • Option 3 (Precise results without error) is misleading as sampling always introduces some degree of sampling error. • Option 4 (Eliminating data cleaning) is not a benefit of sampling. Even with a sample, data cleaning is still necessary. • Option 5 (Including all data points) contradicts the essence of sampling, which uses only a subset of the data.
