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.
