Statistics refer to the systematic collection, analysis, interpretation, presentation, and organization of data. Statistics encompass numerical information based on observed or measured facts. Statistical methods are used to identify patterns, trends, or relationships in the data and draw conclusions.
There are two main types of statistics:
Descriptive Statistics: Describes and summarizes data using metrics such as mean, median, mode, standard deviation, and percentages. The goal is to present the key features of the data.
Inferential Statistics: Draws conclusions or makes predictions about a larger population based on a sample of data. Statistical tests and estimates are used here to infer to the overall population.
Statistics are applied in various fields such as science, economics, medicine, social sciences, and many others to understand data and make informed decisions.
