Statistical techniques are methods used to collect, analyze, and interpret data. They help researchers and analysts make sense of complex information by identifying patterns, trends, and relationships. Common techniques include mean, median, and standard deviation, which summarize data, as well as regression analysis, which explores how different variables interact. These techniques are essential in various fields, such as 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, professionals can make informed decisions based on solid evidence.
