Question

Which of the following are the characteristics of statistics?
A.Numerically expressed
B.Affected by multiplicity of causes
C.Aggregate of facts
D.All of the above

Answer 1

Hint: As we know, statistics deals with quantitative data only which are explained and expressed as numerical facts and figures. Basically, we use quantitative data to represent an aggregate of facts as a simple and understandable numerical data. Through statistics, we use facts for comparison of data and the data can be used to draw conclusions for these facts. It is known, the facts and figures represented by statistics are affected by many other factors. So, we can say that statistics is also affected by multiplicity of causes.

Complete step-by-step answer:
Firstly, we take all the options from the question to figure out which of them are the characteristics of statistics.
We know that statistics refers to data which can be counted and measured. For data to be measured and counted, it should be expressed in the numerical form. Any data under statistics must be expressed in quantitative form. Hence, the facts used in data must be numerically expressed in statistics.
Hence, option A is correct.
We also know that numerical figures and values are based on certain facts. We use numerous data to draw conclusions and to compare the numerical data for all the facts given. Thus, aggregate of facts are one the characteristics of statistics.
Hence, option C is also correct.
Now, we will have a look at the next option which is related to multiplicity of causes. If we are dealing with facts in statistics, then we need to consider the other factors which can affect the data. While figuring out the conclusions based on data and facts, we have to go through the entire phenomenon individually or together to avoid any kind of negative impacts. So, statistics is also affected by multiplicity of causes.
Hence, option B is also correct.
As all the options A, B and C are correct. Therefore, we will choose option D which is all of the above.

Note: In these types of multiple choice questions, we generally choose the first option which we think is correct. Sometimes, we don’t go through all the options. So, it is very important to read and understand all the options and then go for the best one.
