The video tutorial covers the construction and analysis of box plots, focusing on the five-number summary and interquartile range. It uses examples of fish speeds and video game hours to explain data distribution and quartiles. The tutorial also guides viewers through creating a box plot from a data set of dog speeds, emphasizing the importance of understanding data spread and median placement.

What is the estimated minimum speed of the fish according to the box plot?

• 48 mph

• 39 mph

• 35 mph

• 42 mph

Which fish is the fastest according to the box plot?

• Shark

• Marlin

• Sailfish

• Tuna

What does the interquartile range of 9 mph indicate about the fish speeds?

• The range of the slowest fish

• The range of the fastest fish

• The spread of the middle 50% of fish speeds

• The average speed of all fish

If the interquartile range for video game hours is 10, what can we infer?

• All students played exactly 10 hours

• Half of the students played between 10 to 20 hours

• The minimum hours played is 10

• The maximum hours played is 10

What is the median value in the given data set for sketching the box plot?

• 130

• 142

• 168

• 195

Why is the median not centered in the box plot of dog speeds?

• The median is always at the center

• The data is evenly distributed

• The data is skewed towards slower speeds

• The data is skewed towards faster speeds

What is the maximum speed of the dogs according to the data set?

• 45 mph

• 20 mph

• 30 mph

• 36 mph

What is the lower quartile speed of the dogs?

• 28 mph

• 20 mph

• 36 mph

• 30 mph

How many quarters of the data are between 20 and 30 mph for the dogs?

• Three quarters

• Four quarters

• Two quarters

• One quarter

What is the interquartile range of the dog speeds?

• 15 mph

• 8 mph

• 20 mph

• 10 mph
