What are the example of continuous variable?
Height, weight, wavelength of light.
Any numerical or nominal characteristic of a population?
Non-numerical nominal characteristics can be the brands of cars we drive, the names of cities were we live, our race, religion, etc. Numerical nominal characteristics can be area codes, zip codes, numbers on the back of jerseys of basketball players. Numerical, non-nominal data is someone's weight or height.
Is height a continuous variable?
Yes. (Although it is normally recorded in a discrete form.)
Is blood pressure a discrete variable?
No. Because blood pressure is continuous variable. Like temperature, a person's weight and height, the measured value occurs over a continuous scale.
What is difference between a discrete variable and a continuous variable?
a continous variable is one that can assume different values at each point, so if you were measuring height it could be 187.1, 187.2.. 187.8, but this can not be used for something such as measuring the amount of people in a family, because there can't be 3.4 people in a family. This is when discrete variable is used, this measures full numbers.
