To find the median, first arrange the values in ASCENDING ORDER: {0, 2, 4, 5, 8, 11}
Since the set has an EVEN number values, the median will be the average of the two middlemost numbers.
So, median = (4 + 5)/2 = 9/2 = 4.5
Mean = (sum of all values in the set)/(number of values in the set)
= (0 + 4 + 5 + 2 + 11 + 8)/6
= 30/6
= 5
How much greater than the median of the numbers in S is the mean of the numbers in S?
Median = 4.5
Mean = 5
The mean is 0.5 more than the median
Answer: A
