Representative Sample
A representative sample is a subset of a larger population that accurately reflects the characteristics of the entire population. In data science, a representative sample is crucial for making accurate inferences and predictions about the population. To obtain a representative sample, it is important to use a random sampling technique that ensures every member of the population has an equal chance of being selected. The size of the sample should also be large enough to reduce the margin of error and increase the confidence level of the results. A representative sample can help to avoid bias and ensure that the findings can be generalized to the entire population.
