How do I find the median for 77,82,87,85,32,78?
alisha [4.7K]

Answer:

80

Step-by-step explanation:

The median is the middle value of the data arranged in ascending order. If there is no exact middle then the median is the average of the 2 values either side of the middle

Arrange the data in ascending order ( smallest to largest )

32, 77, 78, 82, 85, 87

There is no value exactly in the middle, use the average

median = \frac{78+82}{2} = \frac{160}{2} = 80
