Using the mean formular, the sum of the four scores that are not the median would be 360.
Average or mean score = 450 / 5
Mean score = 90
Hence, median score = mean score = 90
The sum of the 4 scores that are not the median can be calculated thus :
- Total score - median score
Sum of the 4 scores = 450 - 90 = 360
Hence, the sum of the 4 scores that are not the median is 360.
