100 points and brainliest The data to represent average test scores for a class of 16 students includes an outlier value of 78. If the mean, including the outlier of 78, equals 84, which statement is always true about the new data when the outlier is removed? The mean would increase. The mean would decrease. The median would increase. The median would decrease.

The mean would Increase.

Step-by-step explanation:

If you take out the low score, then the average score of the class would go up.

If the mean, including the outlier is 84 and the outlier is below the mean, then if the outlier is removed then the median could increase, it definitely wouldn't decrease, but the new mean would definitely increase.

Step-by-step explanation:

16 x 84 = 1344

if you take out the outlier 1344 - 78 = 1266

1266/15 = 84.4 new mean when outlier is removed.
