is age an ordinal variable?

Consider the variable age. Age is frequently collected as ratio data, but can also be collected as ordinal data. ... Variables that are naturally ordinal can't be captured as interval or ratio data, but can be captured as nominal.

Values, because a variable varies, it must have at least two levels. Levels are simply observed and recorded. Some variables such as height, IQ, and blood pressure are typically measured in the familiar sense of the world.

Age is not necessarily just a number. But it will always be represented as a number because it is the length of time that a person has lived or a thing has existed in the physical world. ... Likewise a 50 year old person can have the maturity level of a 10 year old. But they are still 50.

Ordinal scale has all its variables in a specific order, beyond just naming them. Interval scale offers labels, order, as well as, a specific interval between each of its variable options.

An Example: Age Age is, technically, continuous and ratio. A person's age does, after all, have a meaningful zero point (birth) and is continuous if you measure it precisely enough. It is meaningful to say that someone (or something) is 7.28 year old.

Interval-level variables are continuous, meaning that each value of the variable is one increment larger than the previous and one smaller than the next value. Age, if measured in years, is a good example; each increment is one year. ... Categorical variables can be measured either on nominal or ordinal scales.

It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. ... Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors.

Psykolord1989 . Answer: Continuous if looking for exact age, discrete if going by number of years. If a data set is continuous, then the associated random variable could take on any value within the range.

Ordinal numbers tell us an item's position in a list, for example: first, second, third, fourth, etc. We use ordinal numbers to order and position items and numbers, perhaps to say which position someone came in a race or to recite numbers or place numbers on a number line / time line.

All Answers (16) Categorical for a likert scale as it is an ordinal variable. There is some debate on this topic as some people choose to see it as a continuous variable.

Quasi experiments have independent variables that already exist such as age, gender, eye color. These variables can either be continuous (age) or they can be categorical (gender). In short, naturally occurring variables are measured within quasi experiments.

There are two types of categorical variable, nominal and ordinal. A nominal variable has no intrinsic ordering to its categories. For example, gender is a categorical variable having two categories (male and female) with no intrinsic ordering to the categories. An ordinal variable has a clear ordering.

Ordinal numbers are simply “a thing's position in a series.” (As in, first, second, third, so on and so forth.) ... Yet, understanding what they are in your mind and knowing how to explain ordinal numbers to kids are entirely different. You can say, “one” and show a child one object.

They are nominal, ordinal, interval, and ratio. Data at the nominal level of measurement are qualitative. ... Data at the ordinal level of measurement are quantitative or qualitative. They can be arranged in order (ranked), but differences between entries are not meaningful.

Ordinal (ordered) variables, e.g., grade levels, income levels, school grades. Discrete interval variables with only a few values, e.g., number of times married. Continuous variables grouped into small number of categories, e.g., income grouped into subsets, blood pressure levels (normal, high-normal etc)

There is no order associated with values on nominal variables. [Ratio] Age is at the ratio level of measurement because it has an absolute zero value and the difference between values is meaningful. For example, a person who is 20 years old has lived (since birth) half as long as a person who is 40 years old.
