Question 1
1 / -0

The value of the middle item in a set of observations which has been arranged in an ascending or descending order of magnitude

A
Mean

B
Mode

C
Range

D
Median

Solution

To find the median, you must first order the numbers from smallest to largest.
Question 2
1 / -0

______ is not capable of algebraic treatment

A
Median

B
Arithmetic mean

C
Both

D
None

Solution

Beside algebraic approach, the median value can be estimated also through graphic presentation of data.
Question 3
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
Does not possess the desired algebraic property

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

D
Easily affected by extreme values

Solution

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 4
1 / -0

______ divides the data into 4 equal parts

A
Range

B
Median

C
Mean

D
Quartiles

Solution

Quartiles in statistics are values that divide your data into quarters
Question 5
1 / -0

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

A
Mean

B
Range

C
Mode

D
Median

Solution

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

The ______ is the value you calculate when you want the arithmetic average.

A
Mode

B
Median

C
Mean

D
All of these

Solution

The arithmetic mean, also called the arithmetic average.
Question 7
1 / -0

Which of the Following statement is false regarding Mode

A
Like the median, observations from different data sets have to be merged to obtain a new mode, whether group or ungrouped data are involved

B
Does not possess the desired algebraic property of the mean that allows further manipulations

C
Can be easily identified through ocular inspection

D
Affected by extreme values

Solution

Mode is not affected by the presence of extreme items.
Question 8
1 / -0

Which of the following is NOT a common measure of central tendency?

A
Mode

B
Mean

C
Median

D
Range

Solution

The Range is the difference between the lowest and highest values of the data.
Question 9
1 / -0

The median is ______.

A
The middle point

B
The average

C
The highest number

D
Affected by extreme scores

Solution

Median is that positional value of the variable which divides the distribution into two equal parts.
Question 10
1 / -0

The mean is

A
The midpoint in a set of scores

B
The highest value

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

D
The value that occurs most frequently

Solution

The sum of the values of all observations divided by the number of observations. Mean = ∑X / N
