Question

Identify a nominal, ordinal, interval and ratio variable. Describe how each of these is defined.

Answer 1

Nominal -it is also called the categorical variable scale.. it is defined as a scale used for labeling variables into distinct classifications and doesn’t involve a quantitative value ( order)..... This scale is the simplest of the four variable measurement scales. Calculations can be done on these variables will be futile as there is no numerical value of the options.....

Ordinal-it is defined as a variable measurement scale used to simply identify the order of variables and not the difference between each of the variables. These scales are generally used to depict non-mathematical ideas such as frequency, satisfaction, happiness, a degree of pain....... It is totally straightforward to remember the implementation of this scale as ‘Ordinal’ sounds similar to ‘Order’, which is exactly the purpose of this scale.

Interval-it is defined as a numerical scale where the order of the variables is known as well as the difference between these variables. Variables that have familiar, constant, and computable differences are classified using the Interval scale. It is easy to remember the primary role of this scale too, ‘Interval’ indicates ‘distance between two entities’.........which is what Interval scale helps in achieving.....

Ratio-it is defined as a variable measurement scale that not only produces the order of variables but also makes the difference between variables known along with information on the value of true zero. It is calculated by assuming that the variables have an option for zero, the difference between the two variables is the same and there is a specific order between the options.
