Question

Given the ordered data set: 10, 20, 30, 40, 50, 60, 70, 80. How is its median found?

पर्याय

• Take the value with the highest frequency

• Take the middle number

• Average the 4th and 5th values

• Add all values and divide by eight

Answer 1

Average the 4th and 5th values

Explanation:

There are 8 values, which is an even number.

When the number of values is even, the median is the average of the two middle values.

= (4th value + 5th value) / 2 = (40 + 50) / 2 = 45.
