Median is defined as
“A measure of central tendency identified as the middle value in an ordered array of numerical values, e.g., 7 is the median of (1,4, 6, 6, 7, 9, 11, 22, 41). If the ordered array contains an even number of values, then the median is the mean of the two values on either side of the middle.”

Median
e.g., 7 is the median of (1,4, 6, 6, 7, 9, 11, 22, 41). If the ordered array contains an even number of values, then the median is the mean of the two values on either side of the middle.
