The sample values appear to be currency strings (e.g., "$1,000,000,000") that would need parsing and type conversion before any aggregation operations could be applied. All statistics are null, confirming no numeric analysis was performed. This is a data quality issue requiring preprocessing - the column should be converted to a numeric type before classification can proceed. </reasoning> <table_type_conflict>false</table_type_conflict> </result>
