Question

State whether the following statements are True or False

1) Statistic is a science.

2) Statistics is affected by multiplicity of causes.

3) Statistical laws are not mathematically correct.

4) Statistics is numerically expressed.

5) Statistics cannot be used in research.

Answer 1

1. This statement is true.
Explanation
Statistics is a science that deals with the techniques and methods of collection, classification and presentation of data. Like science, statistics too aggregates facts that are based on cause-and-effect relationship. Thus, statistics is said to be similar to science.

2. This statement is true.
Explanation
Statistical data is affected by a multiplicity of causes. This is because there are various economic and social factors that affect a particular variable and the effect of these factors is very difficult to separate. For instance, the demand for a commodity is affected by the price of other commodities, income of consumers, tastes and preferences, etc. Thus, we can say that statistics is affected by a multiplicity of causes.

3. This statement is false.
Explanation
Statistical laws are mathematically correct. They can be verified.

4. This statement is true.
Explanation
Statistics expresses variables in numerical terms. Qualitative statements cannot be termed as statistics. For example, “poverty has declined” is not a statistical statement. However, “poverty has declined by 2% during 1995-96” can be termed as a statistical statement.

5. This statement is false.
Explanation
Statistical data are significant inputs while conducting various researches. Researchers carry out investigations for studying relationships between different variables. For instance, relations between price and demand, poverty and health, etc are analysed with the help of statistical tools and data.
