In any true experiment, a researcher manipulates an independent variable, to influence a dependent variable, or variables.
Give an example of a testable hypothesis with an independent and dependent variable which you operationally define. Hypothesis: Exercise improves memory. (a) What is the independent variable? (b) What is the dependent variable? Which of the following describes dependent variables in an...

In graphs, the independent variable is on the X-axis, and the dependent variable is on the Y-axis. A dependent variable is the variable being tested in a scientific experiment. The dependent variable is "dependent" on the independent variable. As the experimenter changes the independent variable...
So, if there is any unaccounted for dependent-variable variance, an experiment's set of independent-variables is certainly under-specified and perhaps mis-specified because of the confounding of variables included in this set by causally relevant variables not included in the set. Thus, the proper...
What Is a Dependent Variable? Thedependent variableis the condition that you measure in an experiment. You are assessing how it responds to a change in the independent variable, so you can think of it asdependingon the independent variable. Sometimes the dependent variable is called the "respond...
In stark contrast, dependent variables, also known as "responding variables," are the outcomes or responses measured as a result of changes in the independent variable. They are the "then" in the scientific hypothesis. In our plant growth experiment, the height of the ...
