What are different types of scale?

The four types of scales are:

  • Nominal Scale.
  • Ordinal Scale.
  • Interval Scale.
  • Ratio Scale.

What is a normal scale?

A Nominal Scale is a measurement scale, in which numbers serve as “tags” or “labels” only, to identify or classify an object. A nominal scale measurement normally deals only with non-numeric (quantitative) variables or where numbers have no value. Below is an example of Nominal level of measurement.

What are examples of ratio variables?

Examples of ratio variables include: enzyme activity, dose amount, reaction rate, flow rate, concentration, pulse, weight, length, temperature in Kelvin (0.0 Kelvin really does mean “no heat”), survival time.

What is a ratio level variable?

Levels of measurement The ratio level contains all of the features of the other 3 levels. At the ratio level, values can be categorized, ordered, have equal intervals and take on a true zero. While nominal and ordinal variables are categorical variables, interval and ratio variables are quantitative variables.

How do you measure variables?

You can see that one way to look at variables is to divide them into four different categories ( nominal, ordinal, interval and ratio). These refer to the levels of measure associated with the variables. In everyday usage the convention is to then use the level of measure to refer to the kind of variable.

What is a measured variable?

Unlike in mathematics, measurement variables can not only take quantitative values but can also take qualitative values in statistics.

What is a rank variable?

A rank variable represents the ordering of the values of a numeric variable. By default, ranks are assigned by ordering the data values in ascending order (smallest to largest), then labeling the smallest value as rank 1.
