General rule of thumb: if you can add it, it’s quantitative. For example, a G.P.A. of 3.3 and a G.P.A. of 4.0 can be added together (3.3 + 4.0 = 7.3), so that means it’s quantitative.Click to see full answer. Moreover, is GPA a continuous variable?”Based on the definitions of discrete and continuous data; what type of data is GPA?” Tony: “Since GPA can be any value including decimals between say 1 and 4, for example 3.12 or 1.27, its is continuous.”Secondly, what type of variable is salary? Nominal (Unordered categories) of Data For example, salary can be turned into a nominal variable by defining “high salary” as an annual salary of more than $200,000, “moderate salary” as less than or equal to $200,000 and more than $75,000, and “low salary” as less than or equal to $75,000. Correspondingly, what is the difference between a categorical and continuous variable? Categorical variables contain a finite number of categories or distinct groups. Categorical data might not have a logical order. Continuous variables are numeric variables that have an infinite number of values between any two values. A continuous variable can be numeric or date/time.Is GPA a nominal or ordinal?GPA is an interval measurement; subtraction can be used and distances would make sense. For instance, the distance from 2.3-2.4 is the same distance as 3.7-3.8. Interval and ratio variables collected are often called numerical variables because they provide a number which measures `quantity’ of what you are assessing.
