The table shows a set of data 3 3 3 5 7 9 12
Which is the median of the data set?
To find the median of a set of data, you first need to arrange the data in ascending order:
3 3 3 5 7 9 12
Since there are 7 numbers in the data set, the median is the middle number when the data set is arranged in ascending order. In this case, the middle number is the fourth number:
3 3 3 5 (7) 9 12
Therefore, the median of the data set is 5.
