 Percentiles 2012-10-17 Kenneth pose la question :Question from Kenneth: Hello: What is a common calculation used to determine percentiles? For example, five employees have the following salaries: Office worker 1 - \$25,000 Office worker 2 - \$27,000 Office worker 3 - \$30,000 Office worker 4 - \$32,000 Office worker 5 - \$35,000 What is the percentile rank of office worker 3 who earns \$30,000? Here's what I know: Add the number of salaries. Total: 5 Add the smallest number of salaries less than \$30,000. There are two. Now, divide 2 by 5 and multiply by 100. 2/5 * 100 = 40 I think the office worker making \$30,000 is in the 40th percentile. and I'm not sure what this ranking indicates. I thank you for any helpful reply and or different calculation.Harley Weston lui répond. Why use percentiles? 2011-04-29 Kenneth pose la question :I need some clarification regarding the word "percentile." Here is an example and what I know: If an investor had twenty stocks in his portfolio and five of those stocks paid an annual dividend of \$200.00 or more, the five stocks are in the 25 percentile. Why is this word necessary? If my example and explanation is correct, why not simply indicate that 25% of his stocks paid an annual dividend of \$200.00 or more?Penny Nom lui répond.
