Place the steps for constructing a boxplot to find outliers in the correct order.
Instructions
Plot the five-number summary values in ascending order on the horizontal axis.
Draw a box encompassing the first and third quartiles.
Use an asterisk (or other symbol) to indicate points that are farther than 1.5 x IQR from the box.
Calculate the difference between Q3 and Q1.
Draw a dashed vertical line in the box at the median.

4. Draw a dashed vertical line in the box at the median.
5. Use an asterisk (or other symbol) to indicate points that are farther than 1.5 x IQR from the box.
1. Calculate the difference between Q3 and Q1.
2. Plot the five-number summary values (minimum, Q1, median, Q3, maximum) in ascending order on the horizontal axis.
3. Draw a box, or a rectangle, that encompasses the first quartile (Q1) and the third quartile (Q3) on the axis.
4. Draw a dashed vertical line within the box at the median.
5. Use an asterisk (or other symbol) to mark any individual points that are considered outliers, which are defined as being farther than 1.5 times the interquartile range (IQR) from the box.
