Question
Bobby prepared and shipped a variety of gift baskets that had been ordered. The 9 packages weighed:6 pounds6 pounds8 pounds6 pounds7 pounds9 pounds6 pounds8 pounds6 poundsWhat was the median weight?
Solution
To find the median weight of the packages, you first need to arrange the weights in numerical order:
6, 6, 6, 6, 7, 8, 8, 9
The median is the middle number in a sorted list of numbers. If the list has an odd number of observations, the median is the middle number. If the list has an even number of observations, the median is the average of the two middle numbers.
In this case, we have 8 observations (an even number), so we need to find the average of the 4th and 5th numbers.
The 4th number is 6 and the 5th number is 7.
To find the average of these two numbers, add them together and divide by 2:
(6 + 7) / 2 = 6.5
So, the median weight of the packages is 6.5 pounds.
