Box Plot Skewness

Box plots can display the skew of data. The position of the median relative to the quartiles describes the skew. Match the box plots to the correct graphs below

• 
• 

This is the box plot from question 7. How would you describe the skewness

• The data is symmetrical

• The data is positively skewed

• The data is negatively skewed

Which is the correct box plot for this data?

• 
• 
• 

If you are looking for quartile data, which data plot would you choose to construct?

• Dot Plots

• Histograms

• Box & Whisker Plots

• Movie Plot

• skewed left

• skewed right

• symmetrical

How can you determine if a dataset is skewed based on a box plot?

• Check if the mean is in the center of the box

• Look for outliers within the box plot

• Count the number of data points on each side of the box

• Check if the median is not in the center of the box or if one whisker is longer than the other.

What does a positive skewness in a box plot indicate?

• The distribution is symmetric.

• The left tail of the distribution is longer or more spread out than the right tail.

• The right tail of the distribution is longer or more spread out than the left tail.

• The box plot is not a valid representation of the data.
