There are several ways of classifying of data in statistics. One is by the method of obtaining the data: if you collect the data yourself then they are primary but if you compile them from some existing source, then they are secondary.

Another system of classification is by the nature of the variable: dependent or independent.

A third system depends on whether the data are continuous or discrete. Continuous data can take all possible real values withing a domain; discrete data can take only certain (usually integer) values.

A fourth system is by the nature of the values that the data can take:

Nominal (or qualitative), where there is no inherent ordering of the data: for example, make of car or colour of hair.Ordinal. Such data have an inherent order to them but the differences between the categories are not related. For example, {Agree strongly, agree, disagree, disagree strongly}.Interval scale. On the ordinal scale the difference between two values is clearly defined. However, the zero value is arbitrary, for example in the Celsius or Fahrenheit scales. 10 degrees is not twice as warm as 5 degrees.Ratio scale. On this scale the data are measured on an absolute scale - the zero is not arbitrary.in
