Answer:
(D) The data has an outlier, therefore the range will be much greater than it would be without the outlier.
Step-by-step explanation:
The given data set is:
187, 191, 202, 209, 218, 1984
Outlier: An outlier is an observation point which is quite different from the rest of the given data set points.
(A) This option is not correct because the data set given is already in order.
(B) This option is not correct because an Outlier if present in the data set, then it will definitely have an effect on the range of the given data set.
(C) This option is also incorrect as the data contains outlier, but interquartile range cannot be much greater than it would be without the outlier.
(D) This option is correct because due to the presence of an outlier, range will be much greater than it would be without an outlier.
