Q1 of 55 Page 364

Paid amounts of a day of our 16 friends for going to school and other expenditures are 15, 16, 17, 18, 17, 19, 17, 15, 15, 10, 17, 16, 15, 16, 18, 11

Let us find the mode of paid amounts of a day of our friends.

Mode is just the set of data value that appears most often.

Let us arrange the data values in ascending order so that observation can be made easily.


10, 11, 15, 15, 15, 15, 16, 16, 16, 17, 17, 17, 17, 18, 18, 19


Note the appearances now,


10 appears → 1 time


11 appears → 1 time


15 appears → 4 times


16 appears → 3 times


17 appears → 4 times


18 appears → 2 times


19 appears → 1 time


15 and 17 both appears most times, that is, 4 times.


Thus, mode is 15 and 17.

Making cumulative frequency (greater than type) distribution table of given data, let us drawn Ogive on graph paper.

Drawing less than type Ogive and greater than type Ogive of given data along same axes, on the graph paper, let us find the median from the graph.

Heights (cm) of some students of our class are given below.

131, 130, 130, 132, 131, 133, 131, 134, 131, 132, 131, 133, 130, 132, 130, 133, 135, 131, 135, 131, 135, 130, 132, 135, 134, 133


Let us find the mode of heights of students.
