Statistical methods are techniques used to collect, analyze, interpret, and present data. They help researchers and analysts make sense of complex information by identifying patterns, trends, and relationships. Common statistical methods include descriptive statistics, which summarize data, and inferential statistics, which allow predictions about a larger population based on a sample. These methods are essential in various fields, including healthcare, business, and social sciences. For example, in healthcare, statistical methods can determine the effectiveness of a new treatment by comparing patient outcomes. By applying these techniques, we can make informed decisions and draw meaningful conclusions from data.
