Lindsey found the median and mean of the list of numbers below 4, 6, 8, 8, 15 which statement is true if Lindsey included the number 23 in the list
A. The median would decrease
B. The median wold increase
C. The mean would increase
D. the mean would decrese
In the original list (without including 23), the median is 8 because it is the middle value. The mean is 8.2 because it is the sum of all the numbers divided by 5.
If we include the number 23 in the list, the new list would be: 4, 6, 8, 8, 15, 23.
The median would increase because the new middle value would be 8 (the same as before) but now there are more values greater than 8 than before.
The mean would increase because we added a larger number (23) to the list, which would increase the sum of all the numbers.
Therefore, the correct answer is:
B. The median would increase
C. The mean would increase
You can only pick one
In that case, the correct answer would be:
B. The median would increase.
