TRICKS TO EASILY CALCULATE MEDIAN

EVEN NUMBERS OF TERMS: Even numbers of terms have no “true median” (i.e, one of the numbers already in the list) so you will have to take the average of “half” and “half plus one.”

For example, the median of 102 terms is the average of the \(\frac{102}{2}\)= 51st and 52nd terms.

ODD NUMBERS OF TERMS: Odd numbers of terms are easier. Just divide by 2--you will get a decimal (.5) answer--and then it’s the next integer term.

For example the median of 1,003 terms is the \(\frac{1003}{2}\)= 501.5 --> 502nd term.
