The marks of 12 students in mathematics is as follows:

47, 73, 39, 46, 37, 35, 29, 43, 41, 49, 35, 30

Study the above data and answer the question.

The median of the given data is.

40

Marks given are 47, 73, 39, 46, 37, 35, 29, 43, 41, 49, 35, 30

When these are arranged in ascending order we get their sequence as 29, 30, 35, 35, 37, 39, 41, 43, 46, 47, 49, 73.

Total numbers (n) = 12 (even)

If there is an even number of observation, then there is no single middle value. The median is then usually defined to be the mean of the two middle values.

Hence their median would be = the mean of 39 & 41 = \(\frac{39 + 41}{2}\) = 40
