What is the nonparametric method used to measure ordinal data?
Another method that has been devised for the purpose of measuring ordinal data is the “Classification” method. The process includes the segmentation of data so that each observation is similar to the other.
What is the method of measuring ordinal data?
Another method that has been devised for the purpose of measuring ordinal data is the “Classification” method. The process includes the segmentation of data so that each observation is similar to the other. Then, to maximize classification results, dispersion is measured and minimized in each group.

What is nominal scale variable?
A nominal scale variable is classified into two or more categories. In this measurement mechanism, the answer should fall into either of the classes. It is qualitative. The numbers are used here to identify the objects. The numbers don’t define the object characteristics. The only permissible aspect of numbers in the nominal scale is “counting.”.
Why is interval scale quantitative?
The interval scale is quantitative as it can quantify the difference between the values. It allows calculating the mean and median of the variables. To understand the difference between the variables, you can subtract the values between the variables.
What is ratio scale?
The ratio scale is the 4 th level of measurement scale, which is quantitative. It is a type of variable measurement scale. It allows researchers to compare the differences or intervals. The ratio scale has a unique feature. It possesses the character of the origin or zero points.
