Free Data Handling 01 Practice Test - 4th Grade 

Question 1

Representation of data as rectangular bars with different lengths is called:

A. Bar graph
B. Pictograph
C. Data
D. Scale

SOLUTION

Solution : A

A bar graph is a graph that presents data with rectangular bars with heights or lengths proportional to the values that they represent.  

Question 2

The initial data collected which is not organised is called:

A. Bar graph
B. Grouped data
C. Raw data
D. Graph

SOLUTION

Solution : C

Raw data is data collected from one or many sources. It is data that has not been organised. It needs to be organised so that it can be used.

Question 3

The figure shows the preferred flavour of popcorn among 20 persons.
 
How many people don’t have caramel as the favourite?

A. 18
B. 17
C. 15
D. 16

SOLUTION

Solution : B

On observing the bar graph, we see that
Total number of people who took the survey = (3 + 4+ 7+ 6) = 20
Number of people who like caramel flavour = 3
∴ Number of people who don't prefer caramel flavoured popcorn =20−3=17

Question 4

Height of 12 boys (in cm) are :
143,144,141,145,147,144,142,145,149,151,147,143

 What is the frequency of boys with a height of 143 cm?

A. 2
B. 3
C. 4
D. 1

SOLUTION

Solution : A

Arranging the heights of 12 boys in ascending order we get
141,142,143,143,144,144,145,145,147,147,149,151

The number of times a particular value of data occurs is known as frequency.
Here, we see there are 2 boys with height 143 cm.
Therefore, the frequency of boys with a height of 143 cm is 2.

Question 5

What is the sum of black coloured and white coloured cars sold?

A. 32
B. 37
C. 17
D. 33

SOLUTION

Solution : B

On observing the table we see,
Number of black cars sold = 20
Number of white cars sold = 17

∴ Total number of black and white cars sold = 20+17=37 cars

Question 6

Find the frequency of  symbol ‘-’:
 ×, ×, ÷, -, ×, +, +, ÷, ×, +, -, +, +, -, ÷, ×

A. 1
B. 2
C. 3
D. 4

SOLUTION

Solution : C

The number of times a particular value of data occurs is known as frequency. 
 ×, ×, ÷, -, ×, +, +, ÷, ×, +, -, +, +, -, ÷, ×
Here, we observed that symbol  '-' is occurring thrice, therefore the frequency of '-' symbol is 3.

Question 7

If others include 3 orange cars, 4 green cars and 2 purple cars, what is the difference between the number of red cars sold and number of green cars sold? 

A. 10
B. 15
C. 11
D. 4

SOLUTION

Solution : C

On observing the data,
Given: Red cars = 15
           Green cars = 4

∴ Difference between red cars sold and green cars = 15−4=11 cars

Question 8

The daily rainfall data recorded in a week is shown below. What is the total rainfall recorded on Thursday? (1 drop = 4 inches of rain) 

A. 46 inches
B. 42 inches
C. 44 inches
D. 34 inches

SOLUTION

Solution : C

Given:
1 drop = 4 inches of rain
Rainfall recorded on Thursday = 11 drops
Therefore, the number of inches of rain on Thursday = 4×11=44 inches

Question 9

The daily rainfall data recorded in a week is shown below. On which day of the week is the rainfall the highest? (1 drop = 1 inch rainfall)

A. Monday
B. Thursday
C. Sunday
D. Both Sunday and Monday

SOLUTION

Solution : B

By observing the graph, (1 drop = 1 inch)
Rainfall recorded on Monday = 10 inches
Rainfall recorded on Tuesday = 06 inches
Rainfall recorded on Wednesday = 08 inches
Rainfall recorded on Thursday = 11 inches
Rainfall recorded on Friday = 07 inches
Rainfall recorded on Saturday = 04 inches
Rainfall recorded on Sunday = 09 inches

From above , we can see that Thursday had the heaviest rainfall.
