WebA sample of observations is given: 15, 13, 18.0, 14.5, 12.0, 11, 8.9 and 8.0. Then the question is: By how much could the smallest value (in this case 8) be increased without affecting the value of the sample median? The median is clearly 12.5. So my answer is: to any number less or equal than 12. The more data points (“n”) you have in a sample, the closer your sample median is going to be to the true population median. But you may want to know with a measure of certainty that your calculated statistic is equal to a true population value. In order to do this, run a one sample median test.
