Weekly Quiz Competition

Question 1
1 / -0

In an examination, $$10$$ students scored the following marks in Mathematics: $$35, 19, 28, 32, 63, 02, 47, 31, 13, 98$$. Its range is

A
$$2$$

B
$$96$$

C
$$98$$

D
$$50$$

Solution

Range $$=$$ Maximum value of the variable $$-$$ Minimum value of the variable
$$= 98 - 2 = 96$$
Question 2
1 / -0

The difference between upper and lower limit is called

A
group

B
class marks

C
class size

D
class internal

Solution

Class size = Upper Limit- Lower limit
Question 3
1 / -0

Directions For Questions

Study the following frequency table and choose the appropriate answer :
Class Intervals Frequency
$$0-10$$ $$6$$
$$10-20$$ $$2$$
$$20-30$$ $$13$$
$$30-40$$ $$17$$
$$40-50$$ $$11$$
$$50-60$$ $$4$$
$$60-70$$ $$8$$
$$70-80$$ $$7$$

...view full instructions

The size of the each class intervals is:

A
$$5$$

B
$$0$$

C
$$10$$

D
None of these

Solution

The size of the each class intervals is the difference between the upper and lower limits of any class $$= 10-0 = 10.$$
Question 4
1 / -0

Range of $$14, 12, 17, 18, 16$$ and $$x$$ is $$20$$. Find $$x$$ $$(x > 0)$$

A
$$2$$

B
$$28$$

C
$$32$$

D
Cannot be determined

Solution

Let $$x$$ be the highest no. and here lowest no. is $$12$$
Since, Range $$=$$ Highest value $$-$$ Lowest value
$$\therefore 20 = x - 12 $$
$$\therefore x =32 $$
$$\therefore $$ Option $$C$$ is correct.
Question 5
1 / -0

Which data information can be collected randomly?

A
array

B
primary

C
secondary

D
raw

Solution

Raw data information can be collected randomly.
Example: Consider the height of $$10$$ students in a class given below:
$$55, 36 , 95, 73, 60 , 42 , 25 , 78 , 75 , 62$$
This data in this form is called raw data.
Question 6
1 / -0

An orderly distribution of the raw data into certain specified categories is known as

A
frequency distribution

B
frequency

C
Cumulative frequency

D
Primary data

Solution

Frequency Distribution
The definition of the frequency distribution is distributing the raw data in the specific categories in an order.
Question 7
1 / -0

Data available in unorganized form is called

A
out comes

B
raw data

C
class

D
frequency

Solution

Data available in unorganized form is called raw data
Question 8
1 / -0

Size of the class $$180 - 195$$ is

A
$$180$$

B
$$195$$

C
$$15$$

D
$$-15$$

Solution

Size of class $$= 195 - 180 = 15$$
Question 9
1 / -0

Which one of the following groups has different class size from others?

A
$$120 - 125$$

B
$$243 - 249$$

C
$$141.5 - 146.5$$

D
$$315.5 - 320.5$$

Solution

Class size $$=$$ Upper limit $$-$$ lower limit

All other classes have a class size $$= 5$$ except, $$243-249$$ which has a size of $$6$$
Question 10
1 / -0

The range of the data $$7, 13, 6, 25, 18, 20 , 16 $$ is _____

A
$$13$$

B
$$19$$

C
$$20$$

D
$$25$$

Solution

The data is: $$7,13,6,25,18,20,16$$
Lowest value $$= 6$$
highest value $$= 25$$
Range $$=$$ Highest Value $$-$$ Lowest value $$= 25 - 6 = 19$$
