“half the population is below average.”
Actually, MORE than half of the population is below the average.
Half of the population is below the median.
The median is the middle value in a set of data when the values are arranged in order from smallest to largest. If there is an even number of values, the median is the average of the two middle values.
The average is the sum of all the values in a data set divided by the total number of values in the set, and is sensitive to extreme values and can be skewed by them.
More than half the population doesn’t know what a mean, a median, and a mode are ...
So I use terminology that most are capable of understanding.
