5th Class Mathematics Data Handling Pictograph

    Pictograph

In the pictography data is represented with the help of pictures. Let us understand it with the help of an example:

In the following table number of students present in the class is shown from Monday to Saturday:                

Let us make a pictograph using above information:     

Step 1: Make a picture as a symbol for the students. Here we select a picture of a boy.

Step 2: There were 50 students present on Monday. Drawing 50  before Monday is difficult and tedious job. Therefore, we choose a scale as per our convenience. Here we select = 10 students Thus the number of students present in the class on Monday =

Step 3: Now represent the number of students by the respective number of   

Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
One   represents 10 students.

Example

The number of dolls produced by a factory in different years has been shown in the following pictograph:

2005
2006
2007
2008
2009
2010
2011
One  represents 10000 dolls

Read the above given pictograph and answer the following questions:                

(I) in which year did the factory produce maximum number of dolls?                

(II) how many dolls were produced in 2008?                

(III) in which years did the factory produce equal number of dolls?                

(IV) find the total number of dolls which the factory produced  during 2005 to 2010.                

(V) How many more dolls were produced in 2007 than 2006?

(VI) By how much, production of the dolls increased in 2011 in comparison to previous year.

(VII) In which year 60,000 dolls were produced?  

Explanation

(I) Pictograph shows maximum number of    in 2007. Therefore, 2007 is the year in which maximum number of dolls were produced.

(II) There are 4     in 2008. One represents 10,000 dolls Thus 4 \[=\text{4}\times 10,000=40,000.\]

(III) 2006 and 2009 have equal number of   It shows that the factory produced equal number of dolls in 2006 and in 2009

(IV) Total number of dolls produced during 2005 to 2010 = 70,000 + 30,000 +70,000 + 40,000 + 30,000 + 20,000 = 2,60,000.

(V) The number of dolls produces in \[2006=3\times 10,000=30,000.\] The number of dolls produced in \[2007=7\times 10,000=70,000.\] Difference = 70,000 - 30,000 = 40,000

(VI) The number of dolls produced in \[2010=2\times 10,000=20,000.\] The number of dolls produced in \[2011=6\times 10,000=60,000.\] And \[60,000-20,000=40,000\]

(VII) 60,000 dolls are represented by six
