Pete is conducting a survey to determine his customers’ overall satisfaction about the quality of his company’s products. He sends out surveys to the 5 customers who have purchased the largest number of items over the past year. Are his results likely to be representative of the population he is trying to analyze? Explain.
His results are not likely to be representative of his entire customer base. The sample size of 5 is too small to provide accurate data. Furthermore, by only surveying his top 5 customers, he is creating a selection bias because people who buy the most items are likely already the most satisfied with the products. To get better results, he should use a larger, random sample of all his customers.
