3.

Here is a data set:

1, 2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7

What happens to the mean and standard deviation of the data set when the 7 is changed to a 70?

S.ID.1
S.ID.3
S.ID.2
4.

Here is a data set:

1, 2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 70

1, 2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 70

For the data set with the value of 70, why would the median be a better choice for the measure of center than the mean?
