Gradindelning

Gradindelning is a Swedish term meaning the division or categorization of a continuous scale into discrete levels or intervals. It is used across disciplines to structure information, assessment, and decision-making.

In education, gradindelning describes how student performance is categorized into distinct grades or marks. The exact scales vary by country and institution, and can use letter grades (for example A–F) or numeric scales. Grading criteria define what constitutes each level and are used for reporting, progression, and certification.

In statistics and data analysis, gradindelning refers to binning or discretizing a continuous variable. This involves partitioning the range of a variable into intervals (bins) such as equal-width or equal-frequency bins. The method chosen affects the interpretation of distributions, modeling performance, and data visualization.

In geometry, surveying, and navigation, gradindelning denotes dividing a circle into degrees, minutes, and seconds, or into decimal degrees. This allows precise expression of angles and geographic coordinates.

In industry and agriculture, gradindelning is used for quality grading of products like grain, wood, or metals. Standards define the criteria for each grade, enabling sorting, pricing, and supply-chain decisions.
