Here is what each term means: Nominal: Simply names or call them set of characters Example: Full name, fruits, cars, etc Ordinal: Nominal + They have order Example: Small, medium, big Interval: Ordinal + the intervals between each value are equally split Example: temperature in Fahrenheit scale:10 20 30 etcNote that 20F is not twice as cold as 40F. So multiplication does not make sense on Interval data. But addition and subtraction works. Which brings us tonext point: Ratio Ratio: Interval + multiplication makes sense Weight: 60KG, 120KG.120 KG = 2 * 60 KG I hope the examples are of help when you are working with statistical analysis tools and need to categorize the data. 回答3： 灞曞紑鍏ㄩ儴 Nominal锛氬畾绫汇€佸悕涔夊彉閲忥紝璁℃暟璧勬枡銆佹棤搴忓垎绫昏祫鏂欙紝濡傛€у埆銆佽鍨嬨€?br />Ordinal锛氬畾搴忋€佺瓑绾ц祫鏂欙紝鏈夊簭鍒嗙被璧勬枡锛屽鐤楁晥锛氱棅鎰堛€佹樉鏁堛€佹湁鏁堛€佹棤鏁圛nterval锛氬畾璺濄€佸昂搴﹀彉閲忥紝璁￠噺璧勬枡锛屽娓╁害銆佽韩楂樸€佷綋閲嶃€俁atio锛氬畾姣斻€傚畾姣斿彉閲忓€煎拰瀹氳窛鍙橀噺鍊煎敮涓€鍖哄埆鏄惁瀛樺湪鍩哄噯0銆傚綋鍙橀噺鍊间负0鏃朵笉鏄〃绀烘病鏈変负瀹氳窛鍙橀噺锛屽娓╁害鍙橀噺锛屽綋娓╁害涓?鏃讹紝骞朵笉鏄〃绀烘病鏈夋俯搴︼紝杩欐牱娓╁害灏变负瀹氳窛鍙橀噺锛岃€屼笉鏄畾姣斿彉閲忋€? 回答4： 灞曞紑鍏ㄩ儴
