Is age at last birthday discrete or continuous?

Age of a person at his or her last birthday This variable is discrete because a person’s age at his or her birthday can be listed.

Is age a continuous random variable?

In theory, his/her age can take on any value between zero and plus infinity, so age is a continuous variable. In this example, the age of the person selected is determined by a chance event; so, in this example, age is a continuous random variable.

What type of variable is age?

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.

Is age categorical variable?

Categorical variables represent types of data which may be divided into groups. Examples of categorical variables are race, sex, age group, and educational level.

Can age be a discrete variable?

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 categorical 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 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 education level a continuous variable?

However, educational attainment is not a discrete variable but a continuous one, and the aggregation into different groups may result in a loss of information, thus introducing a potential source of measurement error.

Can age be an ordinal variable?

Is Education continuous or discrete?

Numerical data can be integer-based (discrete) or real numbers (continuous), such as Age, Income, or Education (in years).

Is age a discrete or continuous variable?

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,…

What is the difference between continuous and discrete data?

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.

Are measurements of existing quantities discrete or continuous?

Measurements of existing quantities may seem to be discrete, because they are always specific numbers. But the measured age of, say, “12 years, 153 days” really means a continuous age that is between 12Y152.5D and 12Y153.5D. My point is that it depends on how you need to use the variable, not what is “is.”

Is age continuous or discontinuous?

Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. 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.
