1	X1	20	F	Yes	3400	CSE	Moderate
2	X2	23	M	No	5800		Poor
3	X3	21	M	Yes	6000	CSE	Good
4	X1	25	M	No	2500	CSE	Very Good

Here, the attributes types are- 1) Age and Income are Numeric, 2) Name is Nominal, 3) Dept. is Nominal with 6 possible options, 4) Gender is asymmetric binary with "M" having higher weight, 5) Residential status is symmetric binary, 6) Behavior is ordinal with 5 options. (Very poor < Poor < Moderate < Good < Very Good)
