A continuous series is a type of data representation where values are grouped into intervals or ranges rather than being listed as individual points. This method is often used in statistics to simplify the analysis of large datasets, making it easier to observe trends and patterns. For example, age groups like 0-10, 11-20, and 21-30 can represent a continuous series of ages. In a continuous series, the intervals can overlap or be exclusive, depending on how the data is categorized. This approach is particularly useful in fields such as economics, sociology, and healthcare, where understanding the distribution of data over a range is essential for making informed decisions.
