Question

In a mathematics test given to 15 students, the following marks (out of 100) are recorded : 41, 39, 48, 52, 46, 62, 54, 40, 96, 52, 98, 40, 42, 52, 60 

Find the mean, median and mode of this data.

Answer 1

In a mathematics test given to 15 students, the following marks (out of 100) are recorded : 

41, 39, 48, 52, 46, 62, 54, 40, 96, 52, 98, 40, 42, 52, 60

Mode= 54.8 

(ii) When marks are arranged in ascending order, 

39, 40, 40, 41, 42, 46, 48, 52, 52, 52, 54, 60, 62, 96, 98 

Number of observations = 15 (odd number)

∴ Median = 52. 

(iii) Mode: It is the repeated value. 

Here 52 is repeated three times. 

∴ Mode = 52.
