what is the independent variable in a hypothesis?
151977
A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data. ... The cause is called the independent variable; and the effect is called the dependent variable.

The independent and dependent variables are the two key variables in a science experiment. The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect.

Independent variable: What the scientist changes or what changes on its own. Dependent variable: What is being studied/measured. The independent variable (sometimes known as the manipulated variable) is the variable whose change isn't affected by any other variable in the experiment.

Independent variable is the quantity that the Chemist causes to change. Dependent variable is the quantity that responds to the change the Chemist has caused.

The independent (or manipulated) variable is something that the experimenter purposely changes or varies over the course of the investigation. The dependent (or responding) variable is the one that is observed and likely changes in response to the independent variable.

An independent variable is the cause. Its value is independent of other variables in your study. A dependent variable is the effect. Its value depends on changes in the independent variable.

The independent variables, also known in a statistical context as regressors, represent inputs or causes, i.e., potential reasons for variation or, in the experimental setting, the variable controlled by the experimenter.

In a study where one variable causes the other, the independent variable is the cause. In a study where groups are being compared, the independent variable is the group classification.

Independent variable – the variable that is altered during a scientific experiment. ... Controlled variable – a variable that is kept the same during a scientific experiment. Any change in a controlled variable would invalidate the results.

An independent variable is a variable that you can control. One way to explain it to a child is that it is the variable that the child can change during the experiment. For example, in an experiment on the effect of light on plant growth, the child can control how much light a plant receives.

An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is 'dependent' on the independent variable.

They are alternatively called these names because of their role in research experiments. Independent variables are the variables that determine how dependent variables vary, i.e. they predict dependent variables. Dependent variables, on the other hand, are the variables being predicted by the independent variables.

: a mathematical variable that is independent of the other variables in an expression or function and whose value determines one or more of the values of the other variables.

Variable. (Independent variable) causes a change in (dependent variable). ... The variable being measured in a scientific experiment.

An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables).

Independent variables (also referred to as Features) are the input for a process that is being analyzes. Dependent variables are the output of the process. ... The result (whether a user purchased or not) is the dependent variable.

The independent variable is the variable that you have control over, what you can choose and manipulate. It is usually what you think will affect the dependent variable. In some cases, you may not be able to manipulate the independent variable.
