To find the first quartile, we need to arrange the data set in numerical order:
11, 15, 15, 15, 16, 17, 18, 19, 20, 22, 23
Since there are 11 numbers in the data set, the first quartile will be the average of the 3rd and 4th numbers (in this case, the two 15s).
(15 + 15) / 2 = 15
Therefore, the first quartile of this data set is 15.
11, 15, 15, 15, 16, 17, 18, 19, 20, 22, 23
Since there are 11 numbers in the data set, the first quartile will be the average of the 3rd and 4th numbers (in this case, the two 15s).
(15 + 15) / 2 = 15
Therefore, the first quartile of this data set is 15.
