B. this variable is a discrete numerical variable that is ratio-scaled.

C. this variable is a continuous numerical value that is ratio-scaled.

D. this variable is a discrete numerical variable that is interval-scaled.

E. this variable is a categorical variable that is ordinal-scaled.

F. this variable is a continous numerical variable that is interval-scaled.

Answer 1

Categorical and Numerical Variables: Categorical variables (qualitative) represent types of data which may be divided into groups. Categorical variables can be further categorized as either nominal, ordinal.

numerical variables (quantitative) can take any value.Numerical variables can be further categorized as either interval or ratio variable .

(1) (C) this variable is a continuous numerical value that is ratio-scaled.

(2) (A) this variable is a categorical variable that is nominal-scaled.

(3) (D) this variable is a discrete numerical variable that is interval-scaled.

(4) (E) this variable is a categorical variable that is ordinal-scaled.

(5) (D) this variable is a discrete numerical variable that is interval-scaled.
