Question

Consider the variables of race, age (in years), Gender, Glucose(millimeters per liter), systolic, Blood pressure (millimeters of mercury). Classify these variables as qualitative or quantitative. If the variable is quantitative classify as discreet or continuous. Also, state the level of measurement for each variable: nominal, ordinal, interval, or ratio.

Answer 1

Variable: Race

This is a qualitative variable.

The level of measurement is nominal.

Variable: Age

This is a quantitative variable.

This is a continuous variable, as the age can take any value within interval.

The level of measurement is ratio.

Variable: Gender

This is a qualitative variable.

The level of measurement is nominal.

Variable: Glucose

This is a quantitative variable.

This is a continuous variable, as the variable glucose can take any value within interval.

The level of measurement is ratio.

Variable: Systolic blood pressure

This is a quantitative variable.

This is a continuous variable, as the variable systolic blood pressure can take any value within interval.

The level of measurement is ratio.
