#### Question 1

Draw a histogram to represent the following data .

 Mark obtained 0 – 10 10-20 20-30 30-40 40-50 50-60 No. of student 4 7 12 20 9 2

We take marks obtained on x-axis and no. of students on y-axis. Histogram of the given data is –

#### Question 2

Draw a histogram to represent the  following data .

 Pocket Money 150-200 200-250 250-300 300-350 350-400 No. of student 10 5 7 4 3

#### Question 3

Construct a histogram ………….. distribution :

 Class-interval 5 – 12 13-20 21-28 29-36 37-44 45-52 Frequency 4 7 12 20 9 2

Given class interval in exclusive from and then we will draw the histogram –

Data is exclusive from-

#### Question 4

The following table shows the number of illiterate persons in the age group in a town .

 Age-group 10-19 20-29 30-39 40-49 50-59 60-69 No. of illiterate persons 50 125 190 275 340 410

Draw the histogram to represent the above data.

The give data write in exclusive form and then represent it in histogram as given below.

In exclusive form –

#### Question 5

Draw a histogram to represent the following data .

 Class Mark 150 160 170 180 190 200 Frequency 15 28 12 36 8 18

Draw the histogram to represent the above data.

Here, h = 160 – 150 = 10

Then,

#### Question 6

In a study of diabetic patients in a village, the following  observation were noted .

 Age in year 10-20 20-30 30-40 40-50 50-60 60-70 No. of patients 2 5 12 19 9 4

Represent the above data by a frequency polygon.

Represent the above data by a frequency polygon –

We plot the following points on the graph : (5, 0), (15, 2), (25, 5), (35, 12), (45, 19), (55, 9), (65, 4) and (75, 0) and join them to form a frequency polygon as given below :

#### Question 7

The ages of 360 patient treated in a hospital on a particular day are given below .

 Age in year 10-20 20-30 30-40 40-50 50-60 60-70 No. of patients 90 40 60 20 120 30

Draw a histogram and a frequency polygon on the same graph to represent the above data.

We plot the following points on the graph : (5, 0), (15, 90), (25, 40), (35, 60), (45, 20), (55, 120), (65, 30) and (75, 0) and join them to form a frequency polygon :

#### Question 8

Draw a histogram and the frequency polygon from the following data .

 Class-interval 20-25 25-30 30-35 35-40 40-45 45-50 Frequency 30 24 52 28 46 10

We plot the following points on the graph :

(17.5, 0), (22.5, 30), (27.5, 4, 24), (32.5, 52), (37.7, 28), (42.5, 46), (47.5, 10) and (52.5, 0) and join them to form a frequency polygon :

#### Question 9

Draw a histogram for the following data .

 Class-interval 600-640 640-680 680-720 720-760 760-800 800-840 Frequency 18 45 153 288 171 63

Using the histogram, draw the frequency polygon on the same graph.

The given data with class mark of each class interval :

First we draw a histogram, then polygon.

Now, plotting the mid points –

#### Question 10

Draw a ogive to represent the following data .

 Class-interval 400-450 450-500 500-550 550-600 600-650 650-700 700-750 Frequency 16 25 40 32 18 27 9

The table in cumulative frequency form,

Now, plot the point (450, 16), (500, 41), (550, 81), (600, 113), (650, 131), (700, 158) and (750, 167) on the graph and join them in free hand to get an ogive as shown in the figure.

#### Question 11

Draw an ogive for the following frequency distribution .

 Marks obtained Less than 10 Less than 20 Less than 30 Less than 40 Less than 50 No. of student 8 23 43 50 64

The cumulative frequency table :

Plot the point (10, 8), (20, 23), (30, 43), (40, 50) and (50, 64) on the graph and join them to from an ogive.

#### Question 12

Draw an ogive for the following frequency distribution .

 Class-interval 10-19 20-29 30-39 40-49 50-59 Frequency 21 15 12 19 8

Class interval in exclusive form and cumulative frequency is –

Now, plot the point (19.5, 21), (29.5, 36), (39.5, 48), (49.5, 67) and (59.5, 75) on the graph and  then by joining them to get an ogive as shown-

#### Question 13

Draw a ogive  …………………… following data .

 Class-interval 1-10 11-20 21-30 31-40 41-50 51-60 Frequency 4 6 8 11 7 5

Class interval in exclusive form and cumulative frequency is –

Now, plot the point (10.5, 4), (20.5, 10), (30.5, 18), (40.5, 29), (50.5, 36) and (60.5, 41) on the graph and  then by joining them to get an ogive as shown-
