Question

A researcher studying the behaviour of mice has recorded the time taken by each mouse to locate it's 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 it's food​

Answer 1

Median time spent by mice in searching it's food = 32

Arranging the time taken by the 13 mice in increasing order -

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

The total number of observations is 13(odd).

For odd number of observations the median is equal to the middle term of the observations.

Median time spent by the mice searching for food = 7th term = 32
