2. In a mathematics test gi-uen 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.

Arranging the data in ascending order, we get 39, 40, 40, 41, 42, 46, 48, 52, 52, 52, 54, 60, 62, 96, 98 39 + 40 + 40 + 41+ 42 + 46 + 48 + 52 + 52 + 52 + 54 + 60 + 62 + 96+ 98 (i) Mean = 15 = 822 = 54.8. 15 (ii) For median: n = 15, median is the value of the . 15+ 1 . observation at the - Median = 52. -th place, i.e., 8th place. 2 (iii) Mode: '52' occurs maximum number of times. .. Mode = 52.
