Independent And Dependant Variable. Variables are given a special name that only applies to experimental investigations. An experiment is performed on plants to see how different liquids affect plant growth. Then you can figure out which is the independent variable and which is the dependent variable. The independent variable is the variable the experimenter manipulates or changes and is assumed to have a direct effect on the dependent variable.
Generally the dependent variable is the variable in a function or experiment whose value depends on the independent variable. A Dependent variable is what happens as. In this investigation the independent variable is. The dependent variable is obviously dependent on the independent variable. When we create a graph the independent variable will go on the x-axis and the dependent variable will go on the y-axis. Water apple juice or milk.
The independent variable is the variable the experimenter manipulates or changes and is assumed to have a direct effect on the dependent variable.
The two variables may be related by cause and effect. Independent variable causes a change in Dependent Variable and it isnt possible that Dependent Variable could cause a change in Independent Variable. In a study to determine whether how long a student sleeps affects test scores the independent variable is the length of time spent sleeping while the dependent variable is the test score. Variables are given a special name that only applies to experimental investigations. Independent variables are what we expect will influence dependent variables. The independent variable is the one the experimenter controls.
