After a weekend trip to Universal Studios, a group of students
were asked how many times they rode the Hulk.
The values are: 1, 4, 5, 2, 1, 1, 2, 3, 3, 8, 2

Part A: In this data set, 8 would be an outlier

Part B: The outlier will cause the mean to increase, and the median to be less than the mean

Part C: If the outlier was changed to 5, the interquartile range will stay the same and the standard deviation will decrease.

hope this helps :)
