Is age continuous or discrete variable?
For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous. However, in everyday appliances, all values under 6 years and above 5 years are called 5 years old. So we use age usually as a discrete variable.
Is age quantitative or categorical variable?
In our medical example, age is an example of a quantitative variable because it can take on multiple numerical values. Is age a categorical or continuous variable? A variable is said to be continuous if it can assume an infinite number of real values. Examples of a continuous variable are distance, age and temperature.
What is an example of age continuous?
For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.
What is an example of age as a variable?
For example, a person who is 20 years old has lived (since birth) half as long as a person who is 40 years old. Subsequently, question is, is age a variable in research?
What are discrete variables?
How old is someone if they know their birth date?
Can you classify variables as discrete or continuous?

What types of variable is age?
Quantitative variables are any variables where the data represent amounts (e.g. height, weight, or age). Categorical variables are any variables where the data represent groups.Nov 21, 2019
Is age a continuous dependent variable?
A researcher might also want to consider whether age acts as a moderator variable such that the relationship between an independent and dependent variable changes according to how old a respondent is. Age can be considered as a continuous, ratio variable.
Is age ordinal or continuous?
continuous variableTechnically speaking, age is a continuous variable because it can take on any value with any number of decimal places.Jun 20, 2021
Is age a variable in research?
Anything that can vary can be considered a variable. For instance, age can be considered a variable because age can take different values for different people or for the same person at different times.
Is age continuous or discrete data? + Example - Socratic
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. As an example, suppose that the random variable X, representing your exact age in years, could take on any value between 0 and 122.449315 (the latter value being the approximate age in years of the oldest ...
Which type of variable is age? - AskingLot.com
An Example: Age 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. It is meaningful to say that someone (or something) is 7.28 year old.
What is the difference between discrete and continuous variables?
Quantitative variables are any variables where the data represent amounts (e.g. height, weight, or age).. Categorical variables are any variables where the data represent groups. This includes rankings (e.g. finishing places in a race), classifications (e.g. brands of cereal), and binary outcomes (e.g. coin flips).
Age as a variable: Continuous or categorical? - PMC
Sir, In a strongly worded letter, Mondal[] affirms that age is indeed a number that can be categorized in groups.I agree. In fact, I had stated at least 3 specific circumstances in which this may be desirable: For administrative purposes; when the data cannot be accurately recorded; and when the data are skewed.[]A classical example for the categorization of continuous data is for public ...
Is age nominal ordinal interval or ratio? - FindAnyAnswer.com
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.
What is continuous variable?
For example, an age variable measured continuously could have a value of 23.487 years old—if you wanted to get that specific! A continuous variable is considered ratio if it has a meaningful zero point (i.e., as in age or distance).
Why is age at the ratio level of measurement?
[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. ...

Is age a categorical variable?
Categorical variables take category or label values and place an individual into one of several groups. Quantitative variables take numerical values and represent some kind of measurement. In our medical example, age is an example of a quantitative variable because it can take on multiple numerical values. Is age a categorical or continuous ...
What are discrete variables?
Discrete: Variables that can only take on whole numbers. For example: 1 Number of pets owned by a family (1, 2, 5, etc.) 2 Number of people in a stadium (100, 500, 900, etc.) 3 Number of cookies in a jar (3, 11, 22, etc.)
How old is someone if they know their birth date?
so it’s possible to say that someone is 6.225549 years old. You couldn’t do the same thing with a discrete variable like “number of pets owned” by a family.
Can you classify variables as discrete or continuous?
Using this rule of thumb, you can easily classify most variables as discrete or continuous. However, one variable that can be tricky to classify is age. On one hand, you can count the age of a person in years (e.g. 40 years old) but you could also measure someone’s age to an exact number (e.g. 40.225 years old).
