The marks obtained by 12 students in an examination are 55, 65, 72, 23, 64, 68, 24, 62, 54, 75, 34, and 60. Find the median for the given data.
Answer & explanation
Correct answer: option 1
Arranging the marks obtained by students in ascending order 23, 24, 34, 54, 55, 60, 62, 64, 65, 68, 72, 75
Since the total number of given observations is 12 (even)
So the median will be the average of 6th and 7th observation = \(\frac{60 + 62}{2}\) = 61
