The main advantage of statistics is that information is presented in a way that is easy to analyze, which makes its conclusions easily accessible. Comparative statistical analysis allows people to identify the strengths and weaknesses of different strategies, programs, policies or products across multiple demographics, making it an indispensable tool for decision makers.
Statistics are gathered anonymously, which reduces the reluctance of individuals to volunteer information. This allows researchers to gather data that is otherwise inaccessible. Furthermore, statistical methods are standardized, which makes them easy to replicate and guarantees consistent quality over time. Statistics provides hard data on performance and output, creating an excellent benchmark by which to measure efficiency and productivity.
