If V = {1, 7, 18, 20, 29, 33}, how much less is the mean of the numbers in V than the median of the numbers in V? Select
A) 1.0
B) 1.5
C) 2.0
D) 2.5
E) 3.0
This is a good question to understand the difference between mean and median.   Mean: Average of all the numbers. (Sum of all the elements divided by the number of elements)   Median: Arrange the elements of the set in increasing order. If the number of terms is odd, the middle term is the median. If the number of terms is even, the average of middle two terms is the median   Coming to this question,   Mean = (1 + 7 + 18 + 20 + 29 + 33)/6=
