Question 1
1 / -0

Relationship between mode is

A
Mode = 2Median – 3Mean

B
Mode = 4Median – 2Mean

C
Mode = 3Median – 2Mean

D
Mode = 2Median – 1Mean

Solution

Explanation:

In a normal distribution in which the values of mean, median and mode coincide, (i.e. mean = median = mode) is known as asymmetrical distribution. Mode=3 Median-2 Mean
Question 2
1 / -0

There are two methods of finding mode in discrete series

A
Inspection method and grouping method

B
Mid point method and table method

C
Ascending method and grouping method

D
Descending method and grouping method

Solution

Explanation:

The value of mode can be determined by the both methods of inspection method & grouping method in discrete series.
Question 3
1 / -0

The mean is

A
The value that occurs most frequently

B
The sum of all the values in a group, divided by the number of values in that group

C
The highest value

D
The midpoint in a set of scores

Solution

Explanation:

The sum of the values of all observations divided by the number of observations. Mean = ∑X / N
Question 4
1 / -0

The median is ______.

A
The middle point

B
The highest number

C
Affected by extreme scores

D
The average

Solution

Explanation:

Median is that positional value of the variable which divides the distribution into two equal parts.
Question 5
1 / -0

As a general rule, the _______ is the best measure of central tendency because it is more precise.

A
Median

B
Mode

C
Range

D
Mean

Solution

Explanation:

The mean is usually the best measure of central tendency to use when your data distribution is continuous and symmetrical, such as when your data is normally distributed.
Question 6
1 / -0

______ divides the data into 4 equal parts

A
Quartiles

B
Median

C
Mean

D
Range

Solution

Explanation:

Quartiles in statistics are values that divide your data into
Question 7
1 / -0

Following are the disadvantages of Mean except

A
Cannot be computed if there are missing values due to omission or non-response.

B
Easily affected by extreme values

C
In grouped data with open-ended class intervals, the mean cannot be computed

D
Does not possess the desired algebraic property

Solution

Explanation:

The mean does not possess the desired algebraic property ,the mean has several properties and by virtue of them it can be readily manipulated in varied situation.
Question 8
1 / -0

______ is not capable of algebraic treatment

A
Median

B
None

C
Arithmetic mean

D
Both

Solution

Explanation:

Beside algebraic approach, the median value can be estimated also through graphic presentation of data.
Question 9
1 / -0

MODE

A
The value in the data set that occurs most Number occurs most frequently

B
Ascending or descending order of magnitude

C
The value of the middle item in a set of

D
Observations which has been arranged in an

Solution

Explanation:

Mode is the most fashionable values of a distribution, because it is repeated the highest number of times in the series. It is denoted by Mo.
