How statistics change.

In this questions we are given two data sets. Dataset II is Dataset I with the last value replaced with a higher value.

Dataset I: 27 28 30 30 32 33 Dataset II: 27 28 30 30 32 100 Answer the following about each dataset.

Dataset I: 27 28 30 30 32 33 (a) The median of Dataset I is: 30

(b) The IQR of Dataset I is: 4

(c) The mean of Dataset I is: 30

(d) The standard deviation of Dataset I is:

Dataset II: 27 28 30 30 32 100 (e) The median of Dataset II is: 30

(f) The IQR of Dataset II is: 4

(g) The mean of Dataset II is: 41.17

(h) The standard deviation of Dataset II is:
