Is age nominal or ordinal or interval?
Age can be both nominal and ordinal data depending on the question types. I.e “How old are you” is used to collect nominal data while “Are you the firstborn or What position are you in your family” is used to collect ordinal data. Age becomes ordinal data when there’s some sort of order to it.
What type of variable is age?
Mondal[1] suggests that age can be viewed as a discrete variable because it is commonly expressed as an integer in units of years with no decimal to indicate days and presumably, hours, minutes, and seconds.
Is age an example of interval data?
We can first distinguish between categoric and interval-level data. 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.
Is age group an ordinal variable?
Consider the variable age. Age is frequently collected as ratio data, but can also be collected as ordinal data. This happens on surveys when they ask, “What age group do you fall in?” There, you wouldn’t have data on your respondent’s individual ages – you’d only know how many were between 18-24, 25-34, etc.
Is age a continuous or categorical variable?
Technically speaking, age is a continuous variable because it can take on any value with any number of decimal places. If you know someone’s birth date, you can calculate their exact age including years, months, weeks, days, hours, seconds, etc.
Is age categorical variable?
Examples of categorical variables are race, sex, age group, and educational level. While the latter two variables may also be considered in a numerical manner by using exact values for age and highest grade completed, it is often more informative to categorize such variables into a relatively small number of groups.
Is age ordinal or interval data?
Age is frequently collected as ratio data, but can also be collected as ordinal data. However, many variables that get captured as ordinal have a similar variable that can be captured as interval or ratio data, if you so choose.
Is age a discrete or continuous variable?
Technically speaking, age is a continuous variable because it can take on any value with any number of decimal places. If you know someone’s birth date, you can calculate their exact age including years, months, weeks, days, hours, seconds, etc. so it’s possible to say that someone is 6.225549 years old.
Is age group a categorical variable?
Is age ordinal or continuous?
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.
Is age a categorical or continuous variable?
Is your age a discrete or continuous variable?
Age is either discrete (a count) or continuous depending on how age is measured. Generally, age is specified as a count of the number of full years lived, but it is used as a continuous variables.
Age and Income are continuous numerical variables. (Although the recorded ages have been truncated to whole numbers, the concept of age is continuous.) Number of children is a discrete numerical variable (a count).
Is age a continuous variable?
Age is a continuous variable. Each second we get a bit older. On the other hand, if you specify that the measurement must be by month without fractions, it could technically be a discreet variable. Generally with the amount of variation allowed, it would be considered continuous.
Is age nominal or ordinal?
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.
