Final answer:
The mode is the measure of data that describes the most popular color of vehicle sold.
Step-by-step explanation:
The measure of data that describes the most popular color of vehicle sold is the mode.
The mode is the value that appears most frequently in a data set. In this case, it would represent the color of the vehicle that is sold most often. For example, if red cars are sold more frequently than any other color, then red would be the mode. It is possible for a data set to have multiple modes if there is more than one value that has the highest frequency.
In contrast, the mean represents the average value of a data set, the median represents the middle value of a data set when it is ordered from least to greatest, and the range represents the difference between the highest and lowest values in a data set.
