Step-by-step explanation:
Types of data:
- Categorical data are of two types nominal(N) and ordinal(O).
- Nominal data are the non parametric data,
- Ordinal data are also non parametric data but they are ordered and position matter for ordinal data.
Interval(I) and ratio(R)
- Interval are void of absolute values, that is they can have negative value. Negative value for an interval variable makes sense.
- Ratio are the variable whose true zero exist.
