# Free Data Handling 03 Practice Test - 6th grade

Look at the table, it shows details of types of vehicles present in the basement of an apartment. Each picture of a vehicle represents 5 vehicles. It is clear from the picture that each basement has different rows. Following table provides the information: According to the table shown, how many vehicles are parked in the basement of the apartment?

A.

18 vehicles

B.

25 vehicles

C.

90 vehicles

D.

8 vehicles

#### SOLUTION

Solution : C

In the table shown, each vehicle image represents 5 vehicles.
Number of vehicles in Row 1 =  4 × 5 = 20 vehicles.
Number of vehicles in Row 2  = 5 × 2 = 10 vehicles.
Number of vehicles in Row 3  =  4 × 5 = 20 vehicles.
Number of vehicles in Row 4  = 5 ×5 = 25 vehicles.

Number of vehicles in Row 5 = 5 × 3 = 15 vehicles.

On adding all the vehicles in all the rows, we get

= 20 + 10 +20 + 25 + 15 = 90 Vehicles.

90 Vehicles are parked in the basement of the apartment.

Look at the graph shown, thickness of bars and gap between bars are identical, it shows details of vehicles purchased by members of the residences of same apartment during the year.
1 unit of length represents 2 vehicles purchased.

Number of Vehicles Purchased during the Year Who has purchased the maximum number of vehicles during the year?
Here the horizontal axis is x axis which represents number of vehicles and vertical axis is y axis which represents name of people. The scale for y axis is 1 cm = 1 name and x axis 2 cm = 1 vehicle .

A.

Sophia

B.

Jack

C.

Daniel

D.

Oliver

#### SOLUTION

Solution : A

By looking into the graph you can answer that Sophia has maximum number of cars during that year. Length of bar with respect to Sophia's shows largest, thus she has more number of vehicles than other members in the apartment.

The bar graph shows the favourite subjects of 20 students in class VI 'B'. How many more of them prefer Mathematics to Science?

FAVOURITE SUBJECTS OF 20 STUDENTS Here the horizontal axis is x axis which represents  subjects  and vertical axis is y axis which represents number of students. x axis represents subjects and the scale y axis 1 cm = 1 student.

A.

2

B.

3

C.

4

D.

5

#### SOLUTION

Solution : C

5 of them prefer mathematics and only one prefer science.
So, 5 - 1 = 4

Therefore mathematics is preferred by 4 more students than science.

The marks obtained by Jessica are shown below.  Jenny scored 15% more marks in English than Jessica. What was Jenny's score in English?

Here the horizontal axis is x axis which represents subjects  and vertical axis is y axis which represents marks. x axis represents  and the scale for y axis 1 cm = 10 marks. A. 89
B. 79
C. 60
D. 69

#### SOLUTION

Solution : D

From the graph we can see that Jessica's score for English is 60.

Jenny's score in English is 15% more than Jessica's.

60+15% × 60=60+15100×60

=60+9=69

Jenny's score in English =69

The monitor of your class did a survey, asking each of the students on the number of  magazines they have received. The following are the results:

0,0,3,0,1,4,0,2,5,2,1,0,1,2,6,1,0,0,1,3,2,,1,2,0,0,6,2,2,1,1

Make a tally and answer how many of the students had less than one magazine?

A.

5

B.

9

C.

10

D.

15

#### SOLUTION

Solution : B

Less than one means zero and there were 9 students who did not receive any school magazine. Given below are the marks (out of 100) in mathematics obtained by 40 students of  Class VI in an annual examination. Which section has arranged their marks in ascending order?

A.

VI 'A'

B.

VI 'B'

C.

VI 'C'

D.

VI 'D'

#### SOLUTION

Solution : B

Class VI 'B' has arranged the marks in ascending order as
08 < 12 < 15 < 20 < 45 < 67 < 78 < 88 < 90 < 95

Data and information are the same.

A.

True

B.

False

#### SOLUTION

Solution : B

Data is a collection of facts such as numbers, words, measurements, observations or even just descriptions of things while information is something that we get when we analyse data. Thus, data and information are not the same.

Representation of data with the help of pictures is known as __ .

#### SOLUTION

Solution : A pictograph is a way of showing data using images. It is generally represented by showing images on vertical lines.

Given bar graph shows the runs scored by 6 teammates. Who scored the lowest? A.

Aju

B.

Shubh

C.

Vipul

D.

Shruti

#### SOLUTION

Solution : D

The length of bar shows the value of data being represented. As the bar corresponding to Shruti is the smallest (corresponding to 0 value), she scored the least.

The information represented by a bar graph can never be represented by a pictograph.

A. True
B. False

#### SOLUTION

Solution : B

This statement is false. The information which can be represented by a bar graph can be represented by a pictograph too. However, the preference may vary depending upon convenience and the context.
