1 / -0

combined mean is

A
When mean of three or more than two series is computed collectively

B
When mean of two or more than two series is computed collectively

C
When mean of One or more than two series is computed collectively

D
When mean of only two series is computed collectively

Solution

Combined mean can be computed if we know the mean and number of items in each groups of the data.
Question 2
1 / -0

Shoes manufacturing company only manufactures shoes for adults. Company wants to know the most popular size. Which type of central tendency will be the most appropriate?

Median

B
Range

C
Mode

D
Mean

Solution

Mode is the value that is, most populer or most likely to be sampled.
Question 3
1 / -0

Which diagram is used for finding the value of mode graphically?

A
Bar graph

B
Histogram

C
Pie Char

D
None

Solution

The hight of the rectangles in the histogram is marked by the frequencies of the class interval as shown in the graph .Identify the highest rectangle. This corresponds to the modal class of the series.
Question 4
1 / -0

The most frequently occurring number in a set of values is called the ____.

A
Median

B
Mean

C
Range

D
Mode

Solution

The mode of a set of data values that appears most often or The most frequently occurring.
Question 5
1 / -0

The _______ is often the preferred measure of central tendency if the data are severely skewed.

A
Median

B
Range

C
Mode

D
Mean

Solution

The median is usually preferred to other measures of central tendency when your data set is skewed.
Question 6
1 / -0

Which measure of central tendency takes into account the magnitude of scores?

A
Median

B
Mean

C
Mode

D
Range

Solution

Measures of central tendency describe the distribution of scores around a midpoint. The mean is the most commonly used measure of central tendency
Question 7
1 / -0

When the distribution is of open end classes which average may appropriate

A
Mean

B
Mode

C
Median

D
None

Solution

An open ended distribution means that one or more of your classes are open-ended. In other words, it doesn’t have a boundary. In this frequency distribution table only find median from this data.
Question 8
1 / -0

--- is the half distance between the third and first quartiles

A
S.D

B
Q.D

C
Variance

D
M.D

Solution

Quartile Deviation (QD) means the semi variation between the upper quartiles (Q3) and lower quartiles (Q1) in a distribution. The formula is Q3 - Q1/2.
Question 9
1 / -0

A distribution is skewed if Mean , Median , Mode are

A
Equal

B
Symmetric

C
Not equal

D
None

Solution

This is common for a distribution that is skewed to the similarly, a distribution that is skewed to the typically has a mean smaller than its median and median is smaller than Mode.
Question 10
1 / -0

X > M > Z shows relationship

A
When the distribution is positively skewed

B
mean median and mode are not equal

C
mean median and mode are identical

D
When the distribution is negatively skewed

Solution

A distribution is positively skewed. When Mean> Median>Mode shows relationship.
