Understanding Box and Whisker Plots

What are the 'whiskers' in a box and whisker plot?

• The lines inside the box that show the median

• The lines that connect Q1 and Q3

• The lines that indicate variability outside the quartiles

• The lines that represent the minimum and maximum values

What does the interquartile range (IQR) measure?

• The difference between the median and the maximum value

• The variability of the lowest quartile

• The total range of the data

• The range of the middle half of the data

If the interquartile range (IQR) is small, what does it indicate about the dataset?

• There is a large outlier

• The data points are close together

• The data points are spread out

• The median is very high

How do you find the interquartile range (IQR)?

• Subtract Q1 from Q2

• Add Q1 and Q3

• Subtract Q3 from Q1

• Subtract the maximum value from the minimum value
