Another example of a dependent variable is a test score. How well you perform on a test depends on other variables, such as how much you studied, the amount of sleep you had the night before, whether you had breakfast that morning, and so on. The manipulation of these independent variable...
while the dependent variable isheart rate. To experiment, you would provide stress and measure the subject'sheartbeat. In a good experiment, you'd choose a stress you could control and quantify. Your choice could lead you to perform additional experiments since it might turn out ...
Example Sentences The dependent variable — the thing that may change in response — is how dirty the food gets. From Science News For Students The thing that may change in response is the dependent variable. From Science News For Students Discover More More About Dependent Variable What is a...
The dependent variable is the responding variable. Dependent and independent variables are often used in scientific experiments. For example, if you want to see how the amount of water affects plant growth, you would consider the amount of water as the independent variable and the plant's height...
An independent variable is a variable that you can control. One way to explain it to a child is that it is the variable that the child can change during the experiment. For example, in an experiment on the effect of light on plant growth, the child can control how much light a plant...
Ask yourself which variable is affecting or influencing which other variable. The variable being affected is likely the dependent variable. Try to construct a cause-and-effect sentence with the independent variable being the cause and the dependent variable being the effect. For example, “coffee co...
In science, a variable is a detail or condition that can be controlled or perhaps altered in some way. In scientific investigations, studies are designed that contain three different types of variables: dependent, independent and control.
For example, say you have ten sunflower seedlings, and you decide to give each a different amount of water each day to see if that affects their growth.The independent variable here would be the amount of water you give the plants,and the dependent variable is how tall the sunflowers grow...
First, consider the desire to estimate the effect of an outcome int−1 (Hi,t−1) on the same outcome in timet(Hit). How might the same unobservable affect both the variablesHitandHi,t−1? One example must be that of unobserved health. Recall that one of the data questions above...
Let’s see some potential research studies and identify the dependent variable in them. For example, A researcher wants to understand the relationship between how loud a sound is and how far it travels. They observe a louder sound can reach a listener further away than a softer sound can. ...
