Question 1

Statistical methods are most dangerous tools in the hands of&#10;A)Expert&#10;B)Inexpert&#10;C)Business man&#10;D)All of them

Accepted Answer

Statistical methods can be dangerous in the hands of the inexpert because they may misuse or misinterpret the data, leading to incorrect conclusions and decisions. Experts, on the other hand, are trained to understand and apply these methods correctly.

Question 2

------ is capable of more algebraic treatment&#10;A)arithmetic mean&#10;B)Median&#10;C)Both&#10;D)None

Accepted Answer

The arithmetic mean is capable of more algebraic treatment because it involves operations such as addition and division, which can be manipulated algebraically. The median, on the other hand, is more about the positional value in an ordered list and does not lend itself as easily to algebraic manipulation.

Question 3

------ is considered to best average&#10;A)arithmetic mean&#10;B)Median&#10;C)Mode&#10;D)None

Accepted Answer

The arithmetic mean is considered the best measure of average because it takes into account all values in the dataset, providing a central value that represents the dataset as a whole.

Question 4

------ is used whenever the relative importance of the items in a series differs&#10;A)Simple arithmetic mean&#10;B)Weighted arithmetic mean&#10;C)Geometric mean&#10;D)None

Accepted Answer

The weighted arithmetic mean is used when the relative importance (or weights) of the items in a series differs, allowing for a more accurate representation of the data by giving more importance to certain values.

Question 5

Weighted averages are used in the calculation of&#10;A)death rate&#10;B)birth rate&#10;C)Both&#10;D)None

Accepted Answer

Weighted averages are used in the calculation of both death rate and birth rate to account for the distribution of different population groups, which can affect the overall rate.

Question 6

Median is a ----- average&#10;A)Mathematical&#10;B)Positional&#10;C)Both&#10;D)None

Accepted Answer

Median is considered a positional average because it is determined by the position of numbers in a sorted list, not by performing a mathematical operation on the numbers.

Question 7

----- is not capable of algebraic treatment&#10;A)arithmetic mean&#10;B)Median&#10;C)Both&#10;D)None

Accepted Answer

The median, unlike the arithmetic mean, is not capable of algebraic treatment because it is a positional measure and does not lend itself to algebraic manipulation in the same way that the arithmetic mean does.

Question 8

---- is not a mathematical average&#10;A)A.M&#10;B)G.M&#10;C)H.M&#10;D)mode

Accepted Answer

The mode, which represents the most frequently occurring value in a data set, is not a mathematical average. Unlike the arithmetic mean (A.M), geometric mean (G.M), and harmonic mean (H.M), which are all types of averages calculated using specific formulas, the mode is determined by frequency and does not involve any averaging process.

Question 9

----- is ill-defined&#10;A)arithmetic mean&#10;B)Median&#10;C)Mode&#10;D)None

Accepted Answer

The answer of ----- is ill-defined&#10;A)arithmetic mean&#10;B)Median&#10;C)Mode&#10;D)None...

Question 10

----- divides the data into 4 equal parts&#10;A)Quartiles&#10;B)Mean&#10;C)Median&#10;D)Range

Accepted Answer

Quartiles divide the data set into four equal parts, with each part representing a quarter of the data points.
