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.

This is because the median is the middle number, which doesn't change, while the mean is the average of all scores, which does change. video https://cdn.kastatic.org/googleusercontent/vee3ghmeIKt1n4iD-T_58rZjQzqj7fMhmOvYUqiqjNV8zs81Nek9irVPt_wKKVJPT-r6sDdlxrBuTiZR1kxXuY4 Impact on median & mean: increasing an outlier When a single high score in a group of four friends increases, the mean score also increases, but the median score stays the same.
