Question 4
1 / -0

Which one of the following represents the number $$8$$:

A

B

C

D

Solution
Question 5
1 / -0

In the formula
$$\overline{x} = a + \dfrac{f_i d_i}{f_i}$$,
For finding the mean of grouped data $$di's$$ are deviations from $$a$$ of

A
Lower limits of the classes

B
Upper limits of the classes

C
Mid points of the classes

D
Frequencies of the class marks

Solution

We know,
$$d_i = x_i -a$$
Where,
$$x_i$$ are data and $$'a'$$ is the assumed mean
So, $$d_i$$ are the deviations from of mid-points of the classes.
Hence, the option (C) is correct.
Question 6
1 / -0

For the following distribution:
Class 0-05 5-10 10-15 15-20 20-25
Frequency 10 15 12 20 9
the sum of lower limits of the median class and modal class is

A
$$15$$

B
$$25$$

C
$$30$$

D
$$35$$

Solution

Class Frequency Cumulative Frequency
0-5 10 10
5-10 15 25
10-15 12 37
15-20 20 57
20-25 9 66

From the table
$$N=66$$,
$$N/2 = 66/2=33$$, which lies in the interval $$10-15.$$
Hence, lower limit of the median class is $$10.$$
The highest frequency is $$20,$$ which lies in between the interval $$15-20.$$
Hence, lower limit of modal class is $$15.$$
Therefore, required sum is $$10+15=25.$$
Hence, option (B) is correct.
Question 7
1 / -0

Upper limit of class interval $$ 75-85 $$ is

A
$$ 10 $$

B
$$ -10 $$

C
$$ 75 $$

D
$$ 85 $$

Solution
Question 8
1 / -0

Size of the class $$ 150 -175 $$ is

A
$$ 150 $$

B
$$ 175 $$

C
$$ 25 $$

D
$$ -25 $$

Solution

We know that,
Size of a class $$=$$ Upper limit $$-$$ Lower limit

$$\therefore$$ Size of the class $$ 150-175 $$
$$= 175-150\\=25 $$.

Hence, option (C) is correct.
Question 9
1 / -0

The difference between upper limit and lower limit of a class is known as

A
magnitude

B
range

C
frequency

D
class limits

Solution

The difference between upper limit and lower limit of a class is known as range.
Question 10
1 / -0

Measures of central tendency are known as:

A
Difference

B
Averages

C
Both

D
None of the above

Solution

Central tendency is stated as the statistical measure that represents the single value of the entire distribution or a dataset. It aims to provide an accurate description of the entire data in the distribution. Measures of central tendency is nothing but average. Hence, correct answer is option B.
