The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

But, you remember the mean age of the six children is four. Using this mean, you can find the missing age. The total of all ages equals the mean times the number of children. So, you solve for the missing age and find it's three. video https://cdn.kastatic.org/googleusercontent/49dP0cqpED8vPd2WUomagS1HQJ6MK96VR8TzGURS9NnWoN0IqAspaVajKyL9BgPb0vwsOxDfjbBaO9_ikUPyV2qL Missing value given the mean When babysitting, you forget one child's age from your records.
