Weekly Quiz Competition

Question 1
1 / -0

combined mean is

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

B
When mean of only two series is computed collectively

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

D
When mean of three or more than 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

Following are the disadvantages of Mean except

A
Easily affected by extreme values

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

C
Does not possess the desired algebraic property

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

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 3
1 / -0

What is the mean of this set of numbers: 4, 6, 7, 9, and 2000000?

A
400005.2

B
7.5

C
4

D
7

Solution

Arithmetic mean by direct method isthe sum of all observations in a seriesdivided by the total number ofobservations. Mean = 4+6+7+9+2000000 = 2000026/5= 400005.2
Question 4
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
Median

C
Mode

D
Range

Solution

To find the median, you must first order the numbers from smallest to largest.
Question 5
1 / -0

Which of the following is not a characteristic of the mean?

A
It is best used with ordinal data.

B
The sum of the deviations about the mean is 0.

C
It is affected by extreme scores.

D
It minimizes the sum of squared deviations.

Solution

Mean commonly used measure of central tendency not a number that tells the position of something in a list.
Question 6
1 / -0

In case of symmetrical distribution, mean median and mode are

A
None

B
Skewed to the right

C
Identical

D
Are not equal

Solution

A symmetric distribution is a type of distribution where the left side of the distribution mirrors the right side. In a symmetric distribution, the mean, mode and median all fall at the same point.
Question 7
1 / -0

The ______________ of a sample is the middle value when the data are arranged in ascending or descending rank order.

A
Mode

B
Range

C
Median

D
Mean

Solution

The Median is the “middle” element when the data set is arranged either ascending or descending.
Question 8
1 / -0

Percentiles divide the series into

A
Four equal parts

B
None of these

C
Hundred equal parts

D
Two equal parts

Solution

Percentiles divide the distribution into hundred equal parts, so you can get 99 dividing positions denoted by P1, P2, P3, ..., P99.
Question 9
1 / -0

Measures of central tendency are

A
Descriptive statistics that identify the spread of the scores in a data set.

B
Inferential statistics that identify the spread of the scores in a data set.

C
Descriptive statistics that identify the best single value for representing a set of data

D
Inferential statistics that identify the best single value for representing a set of data

Solution

Inferential statistics allows us to draw conclusions from data that identify the best single value for representing a set of data.
