Which three statements accurately describe dimensions?

Dimensions are fields Tableau uses primarily to categorize, segment, and describe data. They typically contain qualitative information such as names, geographic locations, categories, dates, and identifiers. Therefore, C is correct. Tableau also states that dimensions affect the level of detail in a visualization. Adding another dimension can partition existing marks into more granular groups because Tableau incorporates the field's members into the view's dimensional structure. Therefore, B is correct. The dimension/measure classification is independent from the discrete/continuous classification. Although dimensions are commonly discrete, a dimension can also be continuous. Date fields are a standard example: a date may be represented as a discrete date part or a continuous date value. Therefore, E is correct. Option D instead describes measures, which generally contain quantitative numeric values and are aggregated. Option A is not an inherent defining characteristic of dimensions; formatting behavior depends on how a field is used and whether it is discrete or continuous. Official Tableau guidance identifies dimensions as qualitative fields that group or segment data and explicitly states that dimensions affect the level of detail in the view.
