The column is VARCHAR with mixed formats ("16", "16 yrs", blanks), and numeric statistics are null. Age is an intensive-style attribute (a level, not an extensive quantity), so it would be intensive_additive with mean as the reducer once the values are parsed to numeric. Because the column is dirty text and may be better treated as a dimension attribute than a measure, I abstain with the intensive-style reducers as a tentative fallback. The values should be cleaned (strip "yrs", handle empty strings) before classification is finalized. </reasoning> <table_type_conflict>false</table_type_conflict> </result>
