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. Weight and height are also examples of quantitative variables.
What kind 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 a quantitative discrete variable?
If you’re asked whether age is a continuous or discrete variable in an Introductory Statistics class, the correct answer is technically continuous.
Is age group categorical or quantitative?
Categorical variables represent types of data which may be divided into groups. Examples of categorical variables are race, sex, age group, and educational level.Is age qualitative variable?
The short answer: Age is a quantitative variable because it represents a measurable quantity.
Is age quantitative continuous?
Explanation: Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. … We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.
Is age ordinal or nominal?
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.
Is date a quantitative variable?
Data typeExamplesDate/timeDays of the week (Monday, Tuesday, Wednesday) Months of the year (January, February, March)Why is age an independent variable?
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. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.
Is age a categorical or continuous variable?A great example of this is a variable like 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.
Article first time published onIs year a quantitative variable?
The year is a categorical variable. The ratio between two years is not meaningful which is why its not appropriate to classify it as a quantitative variable.
Is age a ratio or interval?
One question students often have is: Is “age” considered an interval or ratio variable? The short answer: Age is considered a ratio variable because it has a “true zero” value.
Is age range continuous or discrete?
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.
Can age be a discrete variable?
You could turn age into a discrete variable and then you could count it. For example: A person’s age in years. A baby’s age in months.
What is age research?
The concept of age describes how old a person is at a particular point in time. It is defined as the measure of the time elapsed from date of live birth to a specific point in time, usually the date of collection of the data. … ‘Age’ is an attribute of the counting unit ‘person’.
Is age an ordinal level of measurement?
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.
What kind of variables are age and height?
Age, Weight, and Height are quantitative variables.
Is date a continuous variable?
Date is a variable that can be both continuous and discrete. … We could also use date as a continuous variable. In this case each year, quarter, month, day, hour, etc. is a distinct value in a long continuous timeline. Dates from Q1 of 2010 are not grouped with dates from Q1 2011 because these two values are distinct.
Are years continuous variables?
Yes. Not only can you use “year” as a contiuous variable in your model – you should use it like that! Start with plotting the response by year in a scatterplot. … In a GLM, the variable “year” will be associated with one or more coefficients that should have an interpretable meaning in the functional model.
What type of independent variable is age?
Two examples of common independent variables are age and time.
Is age and gender a dependent variable?
An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables).
What are the 3 types of variables?
These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
Is birthday quantitative or qualitative?

What variable is date?
They are ordinal, as one date is bigger than the date before it. It is also quantitative as it can added, subtracted…etc.
What kind of data is year?
∎ Quantitative data consist of values. representing counts or measurements. □ Variable: Year in school.
Is days absent qualitative or quantitative?
Race or ethnicity, grade level, and disabilities/special needs are categorical variables. Number of absences, age, reading test score, and math test score are quantitative variables.
What are examples of quantitative variables?
As discussed in the section on variables in Chapter 1, quantitative variables are variables measured on a numeric scale. Height, weight, response time, subjective rating of pain, temperature, and score on an exam are all examples of quantitative variables.
Is time quantitative or qualitative?
Quantitative Information – Involves a measurable quantity—numbers are used. Some examples are length, mass, temperature, and time. Quantitative information is often called data, but can also be things other than numbers. Qualitative Information – Involves a descriptive judgment using concept words instead of numbers.
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.
