The data to represent average lest scores for a class of 16 students includes an outler value of 78. If the mean, including the outler of 78, equals 84, which statement is always true about the new
The mean would increase
The mean would decrease
The median would increase
The median would decrease

we can deduce that the outlier is lower than the mean set of numbers, because it the mean is higher with the outlier included. Therefore it's inclusion wouldn't allow for an increase-a and b are not true.

the median's decrease, althoigh could occur due to the additiomal number, it is not always true as the question specifies. this is because there could be the same number below the median, which would give the same value.
