Which of the following represents a disadvantage of using the sample range to measure spread or dispersion?
A) It produces spreads that are too large.
B) The sample range is not measured in the same units as the data.
C) The largest or smallest observation (or both) may be an outlier.
D) None of these is correct.
E) All of these are correct.
Sample Range
The difference between the largest and smallest values in a sample, used as a measure of variability.
Outlier
A data point that differs significantly from other observations and can potentially skew results.

Final Answer :
C
Explanation :
The sample range, defined as the difference between the largest and smallest observations in a dataset, can be significantly affected by outliers. If the largest or smallest value is much different from the rest of the data, it can distort the perceived spread of the dataset, making this a disadvantage of using the range as a measure of dispersion.
