A dependent variable is the variable being tested and measured in a scientific experiment . A dependent variable is the variable being tested in a scientific experiment. Example: y = x2. Draw a vertical line, which is the y-axis. A Dependent variable is what happens as a result of the independent variable. The y-axis represents a dependent variable, while the x-axis represents an independent variable. Whenever you take the experimental data, the dependent variable is the thing that needs to be measured. You can use the DRY MIX acronym to remember this: D - dependent variableR - responds to changeY - Y-axis, M - manipulated variable (one you change)I - independent variableX - X-axis. However, the value of y will depend on the value of x. Key Point: In the scientific experiment, keep in mind that you must have a dependent variable. The messiness of a room would be the independent variable and the study would have two dependent variables: level of creativity and mood. But before proceeding to details, lets understand what is variable. We can see from this relationship that f(x) is dependent on the value of x. Cara Lustik is a fact-checker and copywriter.

Referencing the above example, if the independent variable, x, is equal to 12, we can write this in function notation as f(12), and can compute the dependent variable as follows: In this function, f(x) is always 7 less than x. A constant is a known numeric value that is fixed over time. The independent variable is also referred to as the manipulated variable, predictor variable, and explanatory variable, among other things. See more. The response variable is often related to the independent variable, sometimes denoted as the explanatory variable. This is the vertical line or the line that extends upward. Math = Love: Algebra 1 - Introduction To Relations And Functions mathequalslove.blogspot.com. Example: y = x2 x is an Independent Variable y is the Dependent Variable y is 4 if we put in x=2 y is 9 if we put in x=3 etc (See how y gets pushed around by x, it isn't fair at all.) In this case, the independent variable is what the experimenters give each group: the placebo or the medication. Dependent variables therefore represent the output value of a function, and are commonly denoted as y, or f(x). You think rising sea temperatures might affect the amount of algae in the water. The term dependent variable makes sense because the value of this variable is dependent on the independent variable.
