Answer:
---------------------------
To find the median of the given data set, we need to first arrange the data in numerical order:
- 40, 44, 44, 48, 55, 55, 58, 67
There are a total of 8 numbers in this set, which is an even number, so to find the median we need to take the average of the two middle numbers:
- Median = (55 + 48)/2 = 51.5
Therefore, the median of the data set is 51.5.
