Q.Explain the importance of statistics.

Statistics is valuable because it expresses facts precisely in figures, simplifies and condenses large data, enables comparison and the study of relationships, helps forecasting and planning, and supports decision-making by governments, businesses and economists.

Meaning

Statistics, in the plural sense, means numerical data, and in the singular sense it is the science of collecting, classifying, presenting, analysing and interpreting numerical facts. Its importance extends to economics, business, government and research.

Importance / Functions of Statistics

1. Presents facts in a definite form — statistics expresses facts precisely in numbers, which are more convincing and exact than vague statements.
2. Simplifies complex data — large and complex masses of data are condensed into averages, percentages, totals and diagrams that are easy to understand.
3. Helps in comparison — figures for different years, places or groups can be compared with the help of averages, ratios and index numbers.
4. Studies relationships between variables — tools like correlation and regression reveal the relationship between variables such as price and demand.
5. Helps in forecasting — on the basis of past data, statistics helps predict future trends in production, prices, population and demand.
6. Aids policy formation and planning — governments use statistics of income, prices, employment and population to frame economic policies and plans. …

Statistics is valuable because it expresses facts precisely in numbers, condenses bulky data, facilitates comparison, reveals relationships, helps in forecasting and planning, and provides a sound basis for forming and testing economic policy.

Meaning

Statistics, in the plural sense, means numerical data, and in the singular sense it is the science of collecting, organising, presenting, analysing and interpreting such data. In economics it is an indispensable tool because economic phenomena like income, production, prices and employment are largely quantitative.

Importance (functions) of statistics

• Presents facts in definite form: Statistics turns vague statements into precise numerical facts, making them clear and convincing.
• Condenses and simplifies data: It reduces a large mass of figures into a few meaningful measures such as averages and percentages.
• Facilitates comparison: By using totals, averages, ratios and percentages, statistics allows comparison of two or more sets of data over time or between regions.
• Studies relationships: Techniques like correlation and regression reveal the relationship between variables, for example between price and demand.
• Helps in forecasting: Time-series and trend analysis help predict future values of economic variables.
• Aids policy formulation and planning: Governments and businesses use statistics to frame budgets, plans and policies and to test their results. …

Statistics is important because it expresses facts in numbers, simplifies and condenses large data, enables comparison, helps in forecasting and planning, aids policy formulation and testing of theories, and is indispensable to economics, government, business and research.

Meaning

Statistics is the science of collection, organisation, presentation, analysis and interpretation of numerical data. Its importance can be seen from the many uses to which it is put.

Importance of statistics

1. Presents facts in a definite form: statistics expresses facts in exact numerical form, which is more convincing and precise than vague statements.

2. Simplifies complex data: large and complex masses of data are condensed and simplified through averages, percentages, ratios and diagrams, so they become easy to understand.

3. Facilitates comparison: statistical tools (averages, ratios, graphs) make it possible to compare data over time, between regions or between groups.

4. Helps in forecasting and planning: past data are used to predict future trends and to prepare economic plans, budgets and targets.

5. Helps in policy formulation: governments use statistics on population, income, prices and production to frame economic and social policies.

6. Tests and formulates theories: economic theories and laws (such as the law of demand) are tested and verified with the help of statistical data.
