Difference between - median, midrange, average, mode and range

Median

When you arrange the numbers in a sorted order - median is the middle number (left and right of which are equal)

Example

75, 80, 100, 100, 100

In this case, 100 is the median.

Midrange

Lowest + highest divided by 2.

(lowest + highest) / 2

// From above example
(75 + 100) / 2 = 87.5 => Midrange

Average

Sum of all the values divided by total number of values.

(75 + 80 + 100 + 100 + 100) / 5 = 91

Mode

The most commonly occurring number is called a mode. So from our above example, its clear that 100 is the most common and therefore is known as the Mode.

Range

Difference between the highest and the lowest. As per the example above, the range in this case is 100 - 75 i.e. 25.
