Answer:
The median of the data set is 18.5
Explanation:
To find the median of this set of data values, we need to first arrange them in numerical order:
10, 14, 15, 17, 20, 21, 22, 25
The middle value is the median. If there is an odd number of values, there will be exactly one middle value, and if there is an even number of values, the median will be the average of the two middle values.
In this case, there are 8 values, which is an even number. So, we take the average of the sum of the 2 middle numbers:
Median of Data Set = (17 + 20)/2 = 18.5
Therefore, the median of the data set is 18.5.
