Understanding Percentiles and Z-Scores by Mikaela Kaye is a document available to read on EtoBox.
Here are the steps to find the values corresponding to the given percentiles from the data set 5, 7, 9, 11, 13: 1. Arrange the data in ascending order: 5, 7, 9, 11, 13 2. Use the percentile formula to find c for each percentile: - 20th percentile: c = 2 - 40th percentile: c = 4 - 60th percentile: c = 6 - 80th percentile: c = 10 3. For any whole number c, take the average of the cth and (c+1)th values. For fractions, round up c and take that value. - 20th percentile: c = 2, value is 7 - 4
