Is blood pressure nominal or ordinal?

Most physical measures, such as height, weight, systolic blood pressure, distance etc., are interval or ratio scales, so they fall into the general “continuous ” category. Therefore, normal theory type statistics are also used when a such a measure serves as the dependent variable in an analysis.

How do you know if data is ordinal?

Ordinal data is a type of categorical data with an order. The variables in ordinal data are listed in an ordered manner. The ordinal variables are usually numbered, so as to indicate the order of the list. However, the numbers are not mathematically measured or determined but are merely assigned as labels for opinions.

How do you know if a variable is continuous?

If you start counting now and never, ever, ever finish (i.e. the numbers go on and on until infinity), you have what’s called a continuous variable. If your variable is “Number of Planets around a star,” then you can count all of the numbers out (there can’t be an infinite number of planets).

What does ordinal variable measure?

Ordinal Variables And, order means ranking. So the things being measured are in some order. You can have higher and lower amounts. Less than and greater than are meaningful terms with ordinal variables where they were not with nominal variables.

What is an example of a continuous variable?

Quantitative variables can be classified as discrete or continuous. … Continuous variables are numeric variables that have an infinite number of values between any two values.

One example of an ordinal scale could be “movie ratings”.

Is ordinal qualitative or quantitative?

Data at the nominal level of measurement are qualitative. No mathematical computations can be carried out. Data at the ordinal level of measurement are quantitative or qualitative. … Data at the interval level of measurement are quantitative.

What is the difference between nominal and ordinal variables?

In summary, nominal variables are used to “name,” or label a series of values. Ordinal scales provide good information about the order of choices, such as in a customer satisfaction survey. Interval scales give us the order of values + the ability to quantify the difference between each one.

Is age a categorical variable?

Gender and race are the two other categorical variables in our medical records example. … In our medical example, age is an example of a quantitative variable because it can take on multiple numerical values. It also makes sense to think about it in numerical form; that is, a person can be 18 years old or 80 years old.

What is an ordinal question?
