Answer 1

When doctor takes your blood pressure, it's expressed as a measurement with two numbers, with one number in top is called systolic and with one number in bottom is called diastolic.

For example, 102/80 mmHg.

Quantitative variable are those which can be recorded using number. It can be either continuous or discrete.

Those who takes only isolated values called discrete variable.(e.g, 1,2,3,...)

Those who takes any values (decimal number) is called continuous variable.(e.g, 1.12434,2.4463,

...).

​​​Here blood pressure can takes any numerical values, that's why it is called Quantitative, continuous variable.

(1) Systolic Blood pressure (mmHg) is a Quantitative, continuous variable.

(2) Diastolic Blood pressure (mmHg) is a Quantitative, continuous variable.
