Is year categorical or quantitative?

Understand the Problem

The question is asking whether 'year' is considered a categorical variable or a quantitative variable in statistical terms. It aims to clarify the classification of 'year' within data analysis methodologies.

More Information

A year can be considered categorical if it is used to group data. Although years represent numerical values, the ratio between two years does not have meaningful interpretation.

Tips

Sometimes years may be treated as a continuous variable in time series analysis or trend analysis. Context matters when deciding how to treat the year variable.
