How does a large outlier affect the data set?

1 answer:

5 0

A large outlier could affect the data set because it could make the mean larger, which just means that the average number of the set would be a lot bigger than it already is.

An example would be: 1, 3, 5, 19

19 is obviously the large outlier, so to find the mean, we would add everything together then divide by 4.

The mean would be 28/4=7 So 7 is our mean, but if the large outlier were, let's say 50, then the mean would be way larger than it already is.

Mark this question "True" if the argument is VALID, and "False" if the argument is INVALID: If this number is larger than 6, the

sleet_krkn [62]

This argument is no valid although the first part of the statement is valid. If a number is larger than 6 than its square must be larger than 36. But if the number is smaller than 6, its square does not need to be smaller than 36. For example...

(-100)²=10000

-100 is smaller than 6 but its square is bigger.
