Dependent Variable vs Independent Variable Here the teacher does not know the answer. Therefore she thinks that it might be because of the following two reasons:
Some students spend higher-time revising for their tests. Few students are more intelligent than others.
The teacher decides to analyze the effect of revision time. Based on the test performance of that 100 students. Which are the dependent and independent variables? Dependent Variable:
Test Mark (which can be measured from 0 to 100)
Independent Variables:
Revision time (which is measured in hours) Intelligence (which is measured using IQ score)
Example 2:
Now let see another example: How does increment affect employees’ motivation? Independent variable: Increment Dependent variable: Employees motivation
Example 3:
How higher education can lead to higher Income:
Higher education: Independent variable Higher Income: Dependent variable
It is causally affected by education and itself affects Income.
Example of Dependent and Independent Variable
Remembering Variables With DRY MIX
When you plot in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis. The DRY MIX can help keep the variables straight:
D – Dependent variable R – Responding variable Y – Axis on which the dependent or responding variable is graphed- (the vertical axis) M – It is the change variable or manipulated variable which value can be changed using in the experiment I – is the independent variable X – is the axis on which the independent or manipulated variable is graphed.
