Question

A researcher studying the behavior of mice has recorded the time (in seconds) taken by each mouse to locate its food by considering 13 different mice as 31, 33, 63, 33, 28, 29, 33, 27, 27, 34, 35, 28, 32. Find the median time that mice spent in searching its food.

Answer 1

Arrange the value in ascending order we get

27, 27, 28, 28, 29, 31, 32, 33, 33, 33, 34, 35, 63

The number of values = 13 which is odd

Median = `((13 + 1)/2)^"th"` value

= `(14/2)^"th"` value

= 7^th value

7^th value = 32

∴ Median = 32
