Clark is confused by the video. He doesn’t understand why they don’t just present an average number of years that each dog breed lives. Instead, the video presents a range of years for lifespan expectancy. The average number of years would be the ____Blank while the lifespan is the _____Blank.

• mean: standard deviation

• mode: median

• mean: standard deviation

• mode:median

The typical lifespans of the 10 dog breeds are presented in the video. Using that data, determine what the mode for lifespan is for the 10 dog breeds. Describe what the mode is and how you arrived at your answer.
