Types of variables Anumber variableholds numeric data. Examples: a person’s age, a player’s score, the year Astring variableholds a string of alphanumeric characters. Examples: a person’s name, a password, the day of the week ABoolean variablehas only two possible values: true or false...
In a statically typed language, the variable itself has a type; if you have a variable that's an integer, you won't be able to assign any other type of value to it later. Some statically typed languages require you to write out the types of all your variables, while others will deduc...
There can be all different types of independent variables. The independent variables in a particular experiment all depend on the hypothesis and what the experimenters are investigating. Independent variables also have different levels. In some experiments, there may only be one level of an IV. In ...

Types of Random Variables A random variable has aprobability distributionthat represents the likelihood that any of the possible values would occur. Let’s say that the random variable, Z, is the number on the top face of a die when it is rolled once. The possible values for Z will thus...
There are three different types ofvariables:dependentvariables,independent variables, andcontrolvariables.Independentvariablesare the factors that you change.Dependentvariablesare things that are affected by the changes that you make—the results of the tests (whichdependon theindependentvariables).Controlvari...
Types of VariableAll experiments examine some kind of variable(s). A variable is not only something that we measure, but also something that we can manipulate and something we can control for. To understand the characteristics of variables and how we use them in research, this guide is ...
Variable: any characteristic whose value may change from one individual to another Data: observations on single variable or simultaneously on two or more variables Types of variables Categorical variables or qualitative identifies basic differentiating characteristics of the population ...
There are two types of variables: Dependent Variables and Independent variables.Dependent VariablesThe dependent variable is a variable whose value is determined by the quantity another variable takes. For instance, in the equation y = 2x + 3, x can take any value, like 1, 2, 3. However, ...
