This means the difference between the highest and lowest number of cars sold is four. Therefore, it's impossible for any salesperson to have sold more than 10 cars. video https://cdn.kastatic.org/googleusercontent/iIWqj8kxH8qK0tnYNtHBhbErZcdadyCTd35vXN9ccpW2YIBBbybMMnwoRWi-BxxAtbWtVLIYMKXT4Kc58WdpZXA Median & range puzzlers In a car dealership with 11 salespeople, the median number of cars sold is six, and the range of cars sold is four.

To find the interquartile range (IQR), ​first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.   video https://cdn.kastatic.org/googleusercontent/1dM5VIaSdqW2AZdzrYN2VRde7taL_-C1sVBNWw9IfSKnaQ8X-qKdR4G3AE5vC4MVwnjsfZQuQ6cTnshyZdvRon0ZlA Interquartile range (IQR) The IQR describes the middle 50% of values when ordered from lowest to highest.

No! Box and whisker plots seek to explain data by showing a spread of all the data points in a sample. The "whiskers" are the two opposite ends of the data. This video is more fun than a handful of catnip.
