Answers
Answer:
statistics is a branch of mathematics which deals with the collection, presentation, analysis and interpretation of numerical data.
1) Statistics helps in providing a better understanding and exact description of a phenomenon of nature.
2) Statistics helps in the proper and efficient planning of a statistical inquiry in any field of study.
Limitations of statistics;
1) Statistics laws are true on average. Statistics are aggregates of facts, so a single observation is not a statistic. 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.
(5) Only a person who has an expert knowledge of statistics can handle statistical data efficiently.
(6) Some errors are possible in statistical decisions. In particular, inferential statistics involves certain errors. We do not know whether an error has been committed or not.
