Statistics (सांख्यिकी)

• Statistics is the science concerned with developing and studying methods for collecting, analyzing, interpreting and presenting empirical data. Statistics is a highly interdisciplinary field; research in statistics finds applicability in virtually all scientific fields and research questions in the various scientific fields motivate the development of new statistical methods and theory.
• Statistics is a branch of mathematics and a field of study that involves collecting, analyzing, interpreting, presenting, and organizing data. It is a powerful tool for summarizing and making sense of large amounts of information, and it is widely used in various fields such as science, business, economics, social sciences, and more

Key aspects of statistics include:

1. Data Collection: This involves gathering relevant information or data through surveys, experiments, observations, or other methods.
2. Data Analysis: Statistical techniques are used to analyze and process the data. This can involve calculating descriptive statistics, such as mean, median, and standard deviation, and inferential statistics, which are used to make inferences or predictions based on the data.
3. Data Presentation: Statistics helps in presenting the data in a meaningful and understandable way, often through graphs, charts, and tables.
4. Inference: Statistical inference involves drawing conclusions or making predictions about a larger population based on a sample of data. This is a fundamental aspect of statistics and is used for hypothesis testing and making generalizations.

Statistics is crucial in many fields for decision-making, research, and understanding patterns and trends in data. It plays a role in quality control, marketing research, public policy, medical research, and many other areas where data analysis is essential. There are various branches of statistics, including descriptive statistics, inferential statistics, probability theory, and multivariate analysis, each with its own set of techniques and methods.
