what is the dependent variable in my science project?

A dependent variable is what you measure in the experiment and what is affected during the experiment. ... It is called dependent because it "depends" on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable.

Independent vs Dependent Variable Key Takeaways The independent and dependent variables are the two key variables in a science experiment. The independent variable is the one the experimenter controls. ... If the independent variable changes, then the dependent variable is affected.

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. It is the presumed effect.

A dependent variable represents a quantity whose value depends on those manipulations. In the context of a function, the independent variables are the inputs to the function and the dependent variables are the outputs of the function.

The dependent variable is usually graphed on the y-axis, and the independent variable is usually graphed on the x-axis. In addition, the value of the independent variable determines the value of the dependent variable and is used in experiments to test the value of the dependent variable.

A dependent variable is a variable whose variations depend on another variable—usually the independent variable. An Independent variable is a variable whose variations do not depend on another variable but the researcher experimenting.

The dependent variable is the height of the plant, because you predict that the height is going to change DEPENDING on how much water the plant receives. Answer 2: An "Independent variable" can mean a lot of different things. In math, it usually refers to a variable that does not depend on another 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.

All Science Fair Projects For this science fair project, the independent variables are the DC voltage and the concentration of salt in the electrolyte. The dependent variable is the time taken to collect the released hydrogen gas, and will be measured with the stopwatch.

Definitions. In an experiment, the independent variable is the variable that is varied or manipulated by the researcher. The dependent variable is the response that is measured. ... Here the independent variable is the dose and the dependent variable is the frequency/intensity of symptoms.

Remember, an independent variable is the part of the experiment the scientist changes or controls. The dependent variable is the part of the experiment that reacts to the independent variable. ... A constant is the part that doesn't change during the experiment.

Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.

Independent vs Dependent Variables 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.

Dependent variables A dependent variable represents a quantity whose value depends on how the independent variable is manipulated. y is often the variable used to represent the dependent variable in an equation.

An independent variable is a quantity that is directly controlled by the observer or experimenter. The dependent variable, as its name suggests, depends on the independent variable. The dependent variable is often the quantity you want to measure; it the result of the experiment or test.
