If the diameter of a shaft is measured as 80 mm, 81 mm, 82 mm, 83 mm, 84 mm, 85 mm. What is the median of the observed values? Correct Answer 82.5 mm

The diameter of a shaft is measured as 80 mm, 81 mm, 82 mm, 83 mm, 84 mm, 85 mm. The number of observations is even (6). The median is the average of (6/2)th and ((6/2)+1)th value. Therefore, the median is average of 82 mm and 83 mm, which is 82.5 mm.
