Solution
To find the median of a data set, you first need to arrange the data in ascending order.
The given data set is: 19, 21, 18, 17, 18, 22, 12, 46
Arranging this in ascending order gives: 12, 17, 18, 18, 19, 21, 22, 46
Since there are 8 numbers in the data set, the median is the average of the 4th and 5th numbers.
The 4th number is 18 and the 5th number is 19.
So, the median is (18 + 19) / 2 = 18.5
Therefore, the median of the given data set is 18.5.
