The marks obtained by 13 students in an examination are 54, 65, 12, 94, 64, 28, 54, 12, 78, 75, 20, 82, and 40. Find the median for the given data.

54 20 65 12

54

Arranging the marks obtained by students in ascending order 12, 12, 20, 28, 40, 54, 54, 64, 65, 75, 78, 82, 94 Since the total number of given observations is 13 (odd) So the median will be 7th observation = 54
