Question

Quizplus · Accepted Answer

Boxplots are constructed with a five-number summary which includes the minimum, the maximum, the lower quartile, the median, and the upper quartile. These parameters are resistant to outliers and extreme values, making boxplots a robust method of displaying data. Choice B is incorrect because boxplots do contain the median, which is a measure of central tendency. Choice C is incorrect because there is no such thing as a new type of dispersion statistics. Choice D is incorrect because the whiskers represent values either within 1.5 times the interquartile range (IQR) or the minimum and maximum values.
