Can you have 2 independent variables?
No. The value of a dependent variable depends on an independent variable, so a variable cannot be both independent and dependent at the same time. It must be either the cause or the effect, not both! What is an example of an independent and a dependent variable?
Which of two is an independent variable?
The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. Two examples of common independent variables are gender and educational level.
Where do you put the independent variable?
Scientists like to say that the independent variable goes on the x-axis (the bottom, horizontal one) and the dependent variable goes on the y-axis (the left side, vertical one).
How do you find the dependent variable?
The dependent variable is the one that depends on the value of some other number. If, say, y = x+3, then the value y can have depends on what the value of x is. Another way to put it is the dependent variable is the output value and the independent variable is the input value.
Can time be a dependent variable?
Independent variables are generally graphed on the x-axis, while dependent variables are generally graphed on the y-axis. In this question, time is the independent variable and displacement is the dependent variable. This defines time as the independent variable.
How do you know if a variable is independent in statistics?
You can tell if two random variables are independent by looking at their individual probabilities. If those probabilities don’t change when the events meet, then those variables are independent. Another way of saying this is that if the two variables are correlated, then they are not independent.
What is another name for test variable?
Test Variable: another name for the Dependent Variable.
What is the difference between a covariate and an independent variable?
Similar to an independent variable, a covariate is complementary to the dependent, or response, variable. A variable is a covariate if it is related to the dependent variable. This may be the reason that in regression analyses, independent variables (i.e., the regressors) are sometimes called covariates.
How many dependent variables can you have?
A well-designed experiment normally incorporate one or two independent variables, with every other possible factor eliminated, or controlled. There may be more than two dependent variables in any experiment.
Is smoking a dependent or independent variable?
For example, in the research on cigarette-smoking and lung cancer, cigarette-smoking, which has already been done by many subjects, is the independent variable.” (Kerlinger, 1986, p.
What is meant by dependent variable?
Definitions. Dependent Variable. The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables.
What is an independent variable easy definition?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
What is the difference between dependent and independent?
The two main variables in an experiment are the independent and dependent variable. 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.
