Statistical analysis

Definition

Statistical analysis is the process of collecting, organizing, interpreting, and presenting data to uncover patterns, trends, and insights. It plays a crucial role in evaluating data to make informed decisions, revealing connections that may not be immediately obvious. This method is vital in recognizing patterns, validating hypotheses, and supporting arguments in various fields, including journalism, where data is leveraged to tell compelling stories and enhance credibility.
