Is shoe size discrete or continuous?

1. Shoe size is whole number (discrete), but the underlying measure is foot length which is measurement (continuous) data. Even half sizes are still not really measurement but "whole number", because there is nothing between size 8 and 8 1/2. 2.

What type of variable is shoe size?

Then he realized shoe size is an interval variable. An interval variable has a defined interval between values but lacks a zero point. Consider shoe sizes, we can say that the difference in shoe size 8 and shoe size 7 is equal to the difference in sizes 2 and 3. But it doesn't mean that size 6 is 2 times size 3.

Is shoe size discrete random variable?

Shoe size is also a discrete random variable. Blood type is not a discrete random variable because it is categorical. Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable.

Is body size discrete or continuous?

Examples of continuous variables are body mass, height, blood pressure and cholesterol. A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation.

Is pant size a discrete or continuous variable?

Expert Answer

Numerical continuous : continuous variables are numeric variables that have an infinite number of values between any two values. 2. Pant size of a randomly selected male as S, M, L, XL, XXL. It is categorical ordinal variable.

Continuous vs Discrete Data

Is shoe size discrete or categorical?

Shoe size is whole number (discrete), but the underlying measure is foot length which is measurement (continuous) data. Even half sizes are still not really measurement but "whole number", because there is nothing between size 8 and 8 1/2.

Is shoe size a ratio or interval?

Then he realized shoe size is an interval variable. Eureka! An interval variable has a defined interval between values but lacks a zero point. Consider shoe sizes, we can say that the difference in shoe size 8 and shoe size 7 is equal to the difference in sizes 2 and 3.

Is shoe size qualitative or quantitative?

There are two general types of data. Quantitative data is information about quantities; that is, information that can be measured and written down with numbers. Some examples of quantitative data are your height, your shoe size, and the length of your fingernails.

Is the length of a nail discrete or continuous?

1 Answer. The length of a piece of string is a continuous variable. It can have any value, with a accuracy that only depends on the method of measuring.

Is height a discrete variable?

As a result, we can say, that height is a continuous variable. Because we cannot define a specific set of values, that incorporate every possible height of any human being.

Is family size discrete or continuous?

Income is a continuous variable. Household size and number of computers are discrete variables.

What are examples of continuous random variables?

A continuous random variable is one which takes an infinite number of possible values. Continuous random variables are usually measurements. Examples include height, weight, the amount of sugar in an orange, the time required to run a mile.

What are examples of discrete random variables?

A discrete random variable X has a countable number of possible values. Example: Let X represent the sum of two dice. To graph the probability distribution of a discrete random variable, construct a probability histogram. A continuous random variable X takes all values in a given interval of numbers.

Is shoe size linear?

The English linear measure is the oldest shoe sizing system in the world. In 1324, King Edward II introduced the »size« as the standard English unit of shoe measure. One difference in size, also known as one barleycorn, measures 8.46 mm and corresponds to one-third of an inch (an inch is 2.54 cm).

Is shoe size nominal data?

Nominal Level:

Eg: Shoes can be categorized based on type (sports, casual, others) or color (black, brown, others). These categories of shoes has no ordering (greater than, less than, equal to), are mutually exclusive and exhaustive. Hence the type variable for entity shoe is measured at nominal level.

Is weight discrete or continuous?

Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data.

Is age discrete or continuous?

Is Age Discrete or Continuous? Technically speaking, age is a continuous variable because it can take on any value with any number of decimal places.

Is the length of a rock song discrete or continuous?

Determine whether the quantitative variable is discrete or continuous: Length of a rock song. Is the variable discrete or​ continuous? The variable is continuous because it is not countable.

What is a discrete data?

Discrete data is a numerical type of data that includes whole, concrete numbers with specific and fixed data values determined by counting. Continuous data includes complex numbers and varying data values that are measured over a specific time interval.

Is shirt size quantitative or qualitative?

QUALITATIVE (CATEGORICAL) DATA

Examples of categorical variables are gender (male or female) and size of T-shirt (XXS, XS, S, M, L, XL and XXL); yet, these two variables differ in a sense: the first is said to be nominal or purely categorical whilst the second is known as ordinal.

Are sizes nominal?

Measurement. In manufacturing, a nominal size or trade size is a size "in name only" used for identification. The nominal size may not match any dimension of the product, but within the domain of that product the nominal size may correspond to a large number of highly standardized dimensions and tolerances.

What is interval data examples?

Examples of interval data includes temperature (in Celsius or Fahrenheit), mark grading, IQ test and CGPA. These interval data examples are measured with equal intervals in their respective scales. Interval data are often used for statistical research, school grading, scientific studies and probability.

Is age an interval or ratio?

The short answer: Age is considered a ratio variable because it has a “true zero” value. It's possible for an individual to be zero years old (a newborn) and we can say that the difference between 0 years and 10 years is the same as the difference between 10 years and 20 years.

Is size a qualitative variable?

Height, mass, age, and shoe size would all be measured in terms of numbers. So, these categories do not contain qualitative data.
