How statistics can be misused?

Definition, limitations and context. One usable definition is: “Misuse of Statistics: Using numbers in such a manner that – either by intent or through ignorance or carelessness – the conclusions are unjustified or incorrect.” The “numbers” include misleading graphics discussed elsewhere.

Where do we use large numbers in our daily life?

In everyday life, we commonly use a mixture of digits and words to express (read and write) large numbers. For example, most people will find it easier to read 25 billion than 000. To help us interpret a mixture of digits and words, we can think about what they mean.

What is statistics and explain its features?

Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data. Statistics are collected for a predetermined purpose. ▫Statistics are collected in a systemic manner. Statistics must be comparable to each other.

What is the problem with statistics?

While statistics are extremely valuable, they are also notorious for being a means that people use to make false and misleading arguments. Also far too often statistics are obtained by taking a sample from a larger group and assuming the whole group has the same characteristics as the sample.

What is the importance of statistics in our daily life?

It keeps us informed about, what is happening in the world around us. Statistics are important because today we live in the information world and much of this information’s are determined mathematically by Statistics Help. It means to be informed correct data and statics concepts are necessary.

How is statistics important for studying economics?

Yes, statistics is an indispensable tool for studying and understanding the economic problems of a country. By giving a quantitative aspect to qualitative statements, statistics helps in analysing economic problems such as production, consumption, pricing, income distribution, population, unemployment and poverty.

What are the major drawback of statistics?

Statistics deal with groups and aggregates only. (2) Statistical methods are best applicable to quantitative data. (3) Statistics cannot be applied to heterogeneous data. (4) If sufficient care is not exercised in collecting, analyzing and interpreting the data, statistical results might be misleading.

What is the law of statistical regularity class 11?

Based on the mathematical theory of probability Law of Statistical Regularity states that if a sample is taken at random from a population it is likely to possess the characteristics as that of the population. It states that other things being equal larger the size of sample more accurate the results are likely to be.

Why do we study statistics?

To summarize, the five reasons to study statistics are to be able to effectively conduct research, to be able to read and evaluate journal articles, to further develop critical thinking and analytic skills, to act a an informed consumer, and to know when you need to hire outside statistical help.

What is the law of statistical regularity?

Statistical regularity is a notion in statistics and probability theory that random events exhibit regularity when repeated enough times or that enough sufficiently similar random events exhibit regularity. It is an umbrella term that covers the law of large numbers, all central limit theorems and ergodic theorems.

What is the best definition of statistics?

Statistics is a branch of applied mathematics that involves the collection, description, analysis, and inference of conclusions from quantitative data. The mathematical theories behind statistics rely heavily on differential and integral calculus, linear algebra, and probability theory.

Who has given the best definition of statistics?

A.L. Bowley defined statistics as: “Statistics is the science of counting.”

What are the functions of statistics?

(1) Statistics helps in providing a better understanding and accurate description of nature’s phenomena. (2) Statistics helps in the proper and efficient planning of a statistical inquiry in any field of study. (3) Statistics helps in collecting appropriate quantitative data.

What is law of inertia of large numbers?

Law of Inertia of Large Numbers states, “Other things being equal, as the sample size increases, the results tend to be more reliable and accurate.” This is based on the fact that the behavior or a phenomenon en masse. I.e., on a large scale is generally stable.
