The marks obtained by 12 students of a class in the test are:
36, 27, 5, 19, 34, 23, 37, 23, 16, 23, 20, 38

By arranging the marks in ascending order, we have;

5, 10, 19, 20, 23, 23, 23, 34, 36, 37, 38

In the given data 23 occurred the maximum number of times,

So, the model mark = 23

The following table shows the number of students participating in the various games in a school:

Games	Cricket	Football	Basket ball	Tennis
No. Of students	27	36	18	12

Draw a bar graph to represent the above data.

The heights of five players are 148 cm, 154 cm, 153 cm, 140 cm, and 150 cm, respectively. Find the mean height per player.

The class marks of a frequency distribution are

26, 31, 36, 41, 46, 51

Find the true class limits.

The mean of the following frequency distribution is 8. Find the value of p.

x	3	5	7	9	11	13
y	6	8	15	p	8	4

The marks obtained by 12 students of a class in the test are:36, 27, 5, 19, 34, 23, 37, 23, 16, 23, 20, 38
