Sampling is often preferred over using the entire population due to its efficiency in terms of time, cost, and resources. Instead of collecting and analyzing data from every individual in a population, a representative sample is chosen, which reduces the amount of data to be collected and processed. This is especially important when working with large populations where obtaining data from every individual is not feasible due to logistical or financial constraints. Sampling allows data analysts to make reliable inferences about the entire population without the significant investment of time and resources required for full data collection. Why Other Options Are Wrong : A) Incorrect : Sampling does not eliminate the need for data cleaning; the sampled data still needs to be cleaned and processed for analysis. C) Incorrect : While sampling reduces the size of the data, it does not guarantee 100% accuracy. Sampling introduces a margin of error, and results can vary depending on the sampling technique used. D) Incorrect : Sampling often requires more statistical analysis to account for sampling error and variability. It’s not necessarily simpler than analyzing an entire population. E) Incorrect : Sampling does not inherently remove bias. If the sampling method is flawed or biased, the sample can still lead to inaccurate results. Bias in sampling needs to be actively avoided through careful technique selection.
