Question

which statements are true about box plots? choose three correct answers. they help describe sets of data. they include the mean. each section of a box plot represents 25% of the data. they show outliers through really short whiskers. they show the data split into four parts.

Explanation:

• Box - plots are used to describe data sets.
• A box - plot is divided into four sections (lower whisker, lower half, median, upper half, upper whisker), and each of the four main sections (excluding outliers if any) represents 25% of the data.
• The structure of a box - plot (minimum, first quartile, median, third quartile, maximum) inherently shows the data split into four parts.
• Box - plots do not include the mean.
• Outliers are shown as individual points (not through short whiskers).

Answer:
