STAT (Statistics) is a branch of mathematics that deals with collecting, analyzing, interpreting, presenting, and organizing data. It helps us understand and make sense of complex information by summarizing it in a meaningful way. Statistics is widely used in various fields, including science, business, healthcare, and social sciences. In statistics, we often use tools like mean, median, and mode to describe data sets. Additionally, concepts such as probability and hypothesis testing allow researchers to make predictions and draw conclusions based on data. Overall, statistics plays a crucial role in decision-making and research across many disciplines.
