What is the independent and dependent variable in a chart?
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). In graphs with only positive values for x and y, the origin is in the lower left corner.
What is an example of a independent and dependent variable?
Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). Example: Your test score affects how long you sleep.
What is an dependent variable example?
It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
What is the independent variable in an experiment example?
The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
How do you know if it is dependent 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.
What is independent variable on a graph?
Graphing Rules 1. The independent variable is plotted on the abscissa (also called the x-axis or horizontal axis), while the dependent variable is plotted on the ordinate (also called the y-axis or vertical axis). The dependent variable is the one whose value changes as a result of changes in the independent variable.
What is an example of a dependent variable?
A Dependent variable is what happens as a result of the independent variable. For example, if we want to explore whether high concentrations of vehicle exhaust impact incidence of asthma in children, vehicle exhaust is the independent variable while asthma is the dependent variable.
What is the independent variable in research?
In scientific research, the independent variable is the cause of a change in or effect on the dependent variable.
What are the independent and dependent variables in a cause-and-effect relationship?
The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
What axis is the dependent variable on the graph?
The norm is to place the independent variable on the “x”or horizontal axis and the dependent variable on the “y” or vertical axis. For instance, how might a graph look from our example study on the impact of a new medication on blood pressure?
