One way to determine the variable type is whether it is quantitative or qualitative. A quantitative variable can be measured and has a specific numeric value. Examples of quantitative variables include height, weight, age, salary, temperature, etc. Any variables that are not quantitative are qualit...
A nominal scale describes a variable with categories that do not have a natural order or ranking. You can code nominal variables with numbers if you want, but the order is arbitrary and any calculations, such as computing a mean, median, or standard deviation, would be meaningless. Examples ...
Define and give an example of Nominal variables. What does it mean to say that two events are independent or dependent? Give some examples. True or false? The independent variable is the variable you wish to explain. Define and give an example of Qualitative variables. Explain what is meant ...
This variant of ANOVA is used when there are more than two independent variables. For example, a business might use a factorial ANOVA to examine the combined effects of age, income and education level on consumer purchasing habits. Welch’s F-test ANOVA This type of ANOVA is used when the...
under T-Tests & Statistics A-Z A dichotomous variable is a variable that contains precisely two distinct values. Let's first take a look at some examples for illustrating this point. Next, we'll point out why distinguishing dichotomous from other variables makes it easier to analyze your ...

In the preceding examples, an event provides a single value. However, a random variable comprises the entire set of possible values in your sample space. For random variables, statisticians frequently assess the distribution of possible values, including the central tendency, spread, andskewness. Add...

Temperature isa common type of controlled variable. If a temperature is held constant during an experiment, it is controlled. Other examples of controlled variables could be an amount of light, using the same type of glassware, constant humidity, or duration of an experiment. ...
What Is a Copula? Copula is a probability model that represents a multivariateuniform distribution, which examines the association or dependence between many variables. Put differently, a copula helps isolate the joint or marginal probabilities of a pair of variables that are enmeshed in a more comp...
