Knowledge Needed

Median is the middlemost value of the data set.

For example, we have a data set:

1, 7, 5

Line up in least to greatest.

1, 5, 7

Median is 5.

If there is an even amount of terms, the value of the median is the average of the 2 middlemost terms. For example:

1, 7, 16, 8

Line up in least to greatest.

1, 7, 8 , 16

(7 + 8)/2, average: 7.5

Median is 7.5

Line them up in least to greatest.

79 79 79 79 79 83 83 83 83 88 88 88 88 88 93 93 93 93

Middle of the set: 83 & 88 (Because there is an even amount of terms).

83 + 88 = 171

171/ 2= 85.5
