What question can you ask yourself to determine the independent variable?
To identify the dependent variable ask yourself, “What is actually being measured in the experiment?” For example, to test a hypothesis that eating carrots improves vision, the experimenter would manipulate whether or not subjects ate carrots. Thus, eating carrots is the independent variable.
What is the trick to remembering the independent variable?
One way to remember the difference is to literally consider the independent variable as being ‘independent’, because it is the only thing that changes, as everything else in the experiment is controlled.
What is the independent variable for the tadpole diet experiment?
Woodfrog tadpoles grow larger if fed a meat-based diet. What is the independent variable for the tadpole diet experiment? In the tadpole diet experiment, it would be sufficient to test only one single pan of tadpoles that were fed lettuce, and only one single pan of tadpoles fed meat.
Which is true of the independent variable of an experiment?
An independent variable is the variable that is changed in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.
How do you measure an independent variable?
The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation and the independent variables are the inputs to that measurement. In a simple mathematical equation, for example: a = b/c the independent variables, b and c , determine the value of a .
How to determine an independent variable?
Method 1 of 3: Understanding Independent and Dependent Variables. Think of an independent variable as a cause that…
How do you graph an independent variable?
In a graph, the independent variable is always graphed on the x-axis (horizontal, bottom one); whereas, the dependent variable is groups on the y-axis (vertical, side one). This is mainly because the value plotted on the y-axis, always corresponds to the x-axis. The x-axis is always independent of the y-axis.
How do you determine independent and dependent variables?
Independent and dependent variables always go on the same places in a graph. This makes it easy for you to quickly see which variable is independent and which is dependent when looking at a graph or chart. The independent variable always goes on the x-axis, or the horizontal axis. The dependent variable goes on the y-axis, or vertical axis.
