statistical method
Statistics1* * has four measurement scales or four measurement methods. These four measures (name, order, equidistance and equiratio) have different practicability in the statistical process.
By definition, the ratio measurement is zero and the distance between the data is equal.
The distance between interval measurement data is equal and defined, but its zero value is not absolute but self-defined (such as intelligent or temperature measurement).
The significance of ordinal measure is not reflected in its value, but above its order.
The measured value of nominal measurement has no quantitative significance.
