The median calculates the middle value of the total number of data points by dividing by two, if the set of data is an even number such as 30 you must add the value given and one value above and divide by two to get the final result of the median. 1, 9, 10, 12, 13, 14, 20, 21, 26, 27, 28, 30, 32, 35, 36, 36, 37, 40, 40, 42, 42, 45, 47, 48, 50, 51, 52, 52, 53, 57 30 total data points in the set of data, 302 = 15th value is the central value (36), The 16th value is one value above the 15th value from left to right in ascending order. Therefore, the 16th value is 36 add the 15th and the 16th value together and divide by two to get the result = 36+362 = 36 - Is the most repeated number (median) in this set of data. reword it and parpahrase so it soudns better keep the same writing style
