The median is the smallest value for which the cumulative relative frequency is at least 50%. Therefore, the median time is (25.2 + 25.6) ÷ 2 = 25.4 seconds.įor larger data sets, the cumulative relative frequency distribution can be helpful to identify the median. The median is the mean between the data point of rank There are now n = 8 data points, an even number. ![]() ![]() The information is grouped by Rank (appearing as row headers), Times (in seconds) (appearing as column headers). This table displays the results of Rank associated with each value of 200-meter running times. Rank associated with each value of 200-meter running times, updated ![]()
