Data Handling III (Constructions of Bar Graphs) Maths - Data Handling III (Constructions of Bar Graphs)

Consider the following data gathered from a survey of a colony:

Favorite Sport	Cricket	Basket ball	Swimming	Hockey	Athletics
Watching	1240	470	510	423	250
Participating	620	320	320	250	105

Draw a double bar graph choosing an appropriate scale. What do you infer from the bar graph?

1. Which sport is most popular?
2. What is more preferred watching or participating in sports?

Number of children in six different classes are given below. Represent the data on a bar graph.

Class	V	VI	VII	VIII	IX	X
Number of children	135	120	95	100	90	80

1. Which class has the maximum number of children?
2. Which class has the minimum number of children?

How do you choose the scale?

The performance of students in 1st term and 2nd term is as given below. Draw a double bar graph choosing appropriate scale and answer the following:

Subject	English	Hindi	Maths	Science	S. Science
1st term	67	72	88	81	73
2nd term	70	65	95	85	75

1. In which subject, has the children improved their performance the most?
2. Has the performance gone down in any subject?

The following data gives the amount of manure (in thousand tonnes) manufactured by a company during some years:

Year	1992	1993	1994	1995	1996	1997
Manure (in thousand tonnes)	15	35	45	30	40	20

Represent the above data with the help of a bar graph.

1. Indicate with the help of the bar graph the year in which the amount of manure manufactured by the company was maximum.
2. Choose the correct alternative:

The consecutive years during which there was maximum decrease in manure production are:

1. 1994 and 1995
2. 1996 and 1997
3. 1992 and 1993
4. 1995 and 1996

Following data gives total marks (out of 600) obtained by six children of a particular class.

Students:	Ajay	Bali	Dipti	Faiyaz	Gotika	Hari
Marks Obtained:	450	500	300	360	400	540

Represent the data by a bar graph.
