Question 1
1 / -0

A specific characteristic of a population is known as a __________.

A
Sample

B
Parameter

C
Statistic

D
Descriptive statistic
Question 2
1 / -0

If the minimum value in a set is $$15$$ and its range is $$55$$, the maximum value of the set is _______.

A
$$40$$

B
$$60$$

C
$$80$$

D
$$70$$

Solution

Range is defined as the difference between the highest(or largest ) and lowest(or smallest) observed value in a series. It is the most simple and commonly understandable measures of dispersion.

Range = 55

In the given series, H= x and L= 15

Range => x-15 = 55
=> x = 55+15 = 70
Question 3
1 / -0

Time series is an important statistical technique which is widely used by __________.

A
business executives

B
financial analysts

C
economists

D
all of above
Question 4
1 / -0

The range from the following observations is
$$10, 18, 20, 28, 15, 17, 22, 25, 29, 32, 34$$

A
$$24$$

B
$$20$$

C
$$30$$

D
$$42$$

Solution

Range is defined as the difference between the highest(or largest ) and lowest(or smallest) observed value in a series. It is the most simple and commonly understandable measures of dispersion.
Range = H - L
In the given series, H= 34 and L+ 10
Range = 34-10 = 24.
Question 5
1 / -0

The co-efficient of range from the following observations is
$$10, 18, 20, 28, 15, 17, 22, 25, 29, 32, 34$$

A
$$0.6$$

B
$$0.5$$

C
$$0.55$$

D
None of them

Solution

Range is defined as the difference between the highest(or largest ) and lowest(or smallest) observed value in a series. It is the most simple and commonly understandable measures of dispersion.
Range = H - L
In the given series, H= 34 and L+ 10
Range = 34-10 = 24.
Coefficient of range is found by dividing the range with the sum of highest and lowest value of the series.
Coefficient of range (CR) = R/ (H+L)
=24 / (34+10)
= 24/ 44 = 0.55
Question 6
1 / -0

Stubs are ______________.

A
heading for the vertical column

B
heading of the horizontal column

C

C
Head note

D
Both b&c
Question 8

The formulae of CAPABILITY is __________.

A
C = F (TA, IS, S)

B
C = Capabilities (TA + IA)

C
None of these

D
All of these
Question 9
1 / -0

Given the following set of data, what is the range 12 23 34 54 21 8 9 67:

A
55

B
59

C
8

D
56

Solution

Range is defined as the difference between the highest(or largest ) and lowest(or smallest) observed value in a series. It is the most simple and commonly understandable measures of dispersion. Therefore, it is the most affected measures of dispersion by the extreme values of the series.

Range = H - L

In the given series, H= 67 and L= 12

Range = 67 -12 = 55 .
Question 10
1 / -0

Study the graph and answer the questions.
In which year the sale of cool-sip is minimum?

A
1990

B
1992
