Answer: 9
Concept:
The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half.
In other words, the median of a set of data is the middlemost number or center value in the set.
Solve:
STEP ONE: Line up the terms in the set from least to most
Given = 2, 7, 10, 8, 9, 10, 15
Line up = 2, 7, 8, 9, 10, 10, 15
STEP TWO: Find the middlemost number
Given = 2, 7, 8, 9, 10, 10, 15
Since it is an odd set, therefore there should be the equal number of terms in the lower and higher half.
There are in total seven terms, therefore, the 4th term would be the middlemost, which is
.
Hope this helps!! :)
