## Study Notes

Statistics is a branch of applied mathematics that involves the collection, description, analysis, and inference of conclusions from quantitative data It is an important subtopics of Maths that helps to represent complicated data in a very easy and understandable way Statistics is used in various fields, including psychology, geology, sociology, weather forecasting, probability, and more

The two major areas of statistics are descriptive statistics and inferential statistics Descriptive statistics describes the properties of sample and population data, such as mean, median, mode, and data sets Inferential statistics uses those properties to test hypotheses and infer conclusions about a population from a sample

Mean, median, and mode are different measures of center in a numerical data set The mean is the most used and most important of the three measures of center The median is the middle number when the data is sorted in order The mode is the most frequent number in the data set

Statistics is applicable in various fields, such as applied statistics, theoretical statistics, mathematical statistics, and more It is used in areas such as psychology, geology, sociology, weather forecasting, probability, and more

The methods in statistics involve collecting, summarizing, analyzing, and conclusively understanding the data The goal of statistics is to gain understanding from the data, focusing on applications, and hence, it is distinctively considered as a mathematical science

Statistics is used in virtually all scientific disciplines, such as the physical and social sciences, as well as in business, the humanities, government, and manufacturing It is an integral part of understanding the properties of large sets of objects or events

The summary statistics table is generally used to represent big data related to population, unemployment, and the economy to be summarized systematically to interpret the accurate result

The methods in statistics involve collecting, summarizing, analyzing, and conclusively understanding the data The goal of statistics is to gain understanding from the data, focusing on applications, and hence, it is distinctively considered as a mathematical science

Statistics is used in many sectors such as psychology, geology, sociology, weather forecasting, probability, and much more The goal of statistics is to gain understanding from the data, focusing on applications, and hence, it is distinctively considered as a mathematical science
