Categorical Variable

A categorical variable is one that is qualitative. Quantitative variables (also called numerical variables) are not categorical variables. Categorical variables sort data by two or more categories. There is no ranking of priority or dominance or order of any sort with categorical variables. Ordering variables are called ordinal variables and are not categorical. Categorical variables--also called nominal variables--assign data to categories that are equally weighted, like "male" and "female" or "in school" and "graduated school."

Numerical Variable

Numeric variables are quantitative variables (numeric variables can never be qualitative categorical variables). In numeric variables, numbers represent counts of things and measurements of things. The variable may take on a value within a finite interval, like height or weight, or it may take on a value within an infinite interval, like 103,000,000,000 light years. A numerical variable has interval values that can be interpreted, such as being added or subtracted.

Psychological Construct

A psychological construct is a defined system of thought or theory through which human behavior can be understood. Some psychological constructs are consciousness, intelligence, group culture. Constructs, like test anxiety, allow for labeling covarying behaviors and, if extended that far, for identifying cause of behavioral covariants.

Psychological Measure

Procedures developed to measure people's characteristics, such as intelligence or introversion. Psychological measures can determine aptitude or organizational tendency or can be used to predict future reactions or behaviors. To be comparatively meaningful, individual measurements can be compared to group measurements.

Thanks Karen! but that's not the answer that I'm looking for. Please see the format below:
