Statistics

Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data. It provides tools to summarize and make inferences from quantitative information, allowing researchers and analysts to draw conclusions about populations based on sample data. Statistics is divided into two main areas: descriptive statistics, which focuses on summarizing and presenting data clearly, and inferential statistics, which involves making predictions or generalizations about a population based on sample data. Key concepts in statistics include measures of central tendency (such as mean, median, and mode), variability (such as range, variance, and standard deviation), and probability distributions. Ultimately, statistics is essential in various fields, including science, social sciences, business, and healthcare, as it aids in decision-making and understanding complex phenomena through data-driven insights.
