Which branch of statistics is used for grouping and organizing data?

Descriptive statistics is the branch of statistics that focuses on summarizing and organizing data to provide a clear understanding of its main features. This includes the use of measures such as means, medians, modes, ranges, and standard deviations, as well as visual tools like graphs and charts. By employing descriptive statistics, one can effectively present both quantitative and qualitative data in a manner that is straightforward and interpretable, allowing for a more immediate grasp of the data's characteristics and patterns.

In practice, descriptive statistics are essential for initial data analysis, as they allow researchers and analysts to condense large volumes of information into digestible summaries. This foundational step often guides further insights and decisions, paving the way for more complex analyses.
