The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).
Why is the independent variable placed on the x-axis?
In any data set, the independent or X-variable is the one that was chosen or manipulated by the experimenter. For example, time is always an independent variable (and goes on the x-axis) because the experimenter is choosing which time points to take measurements at—1 second intervals, 5 minute intervals, etc.
Does the independent variable have to be on the x-axis?
Scientists like to say that the independent variable goes on the x-axis (the bottom, horizontal one) and the dependent variable goes on the y-axis (the left side, vertical one).
Which variable should be on the x-axis?
The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).
Why is X the independent variable and y the dependent?
Mentor: In this equation, what are the independent and dependent variables? Student: Well, for any value of x, you have to multiply it by two and then add one to get y, so y is dependent on x. The independent variable is x, and the dependent variable is y.
Where does the independent variable go on a table?
The independent variable usually goes in the columns, while the dependent variable goes in the rows. Rows and columns intersect at cells.
Is the independent variable manipulated?
A manipulated variable is the independent variable in an experiment. It’s called “manipulated” because it’s the one you can change. … An experiment generally has three variables: The manipulated or independent variable is the one that you control.
Does the independent variable change?
There are two types of variables-independent and dependent. … Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
Is the independent variable the cause or effect?
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.

How do you distinguish between dependent and independent variables?
- Independent variables in research can be manipulated or altered to see their impact on other variables.
- The dependent variable is dependent on other variables. It is the variable that is measured or tested by a researcher.
How do you know if a variable is independent or dependent?
The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected.
How do you find the 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 the dependent variable in a data table?
The dependent variable is the variable that changes as a result of you manipulating or changing the independent variable. All data tables have at least one independent variable and at least one dependent variable.
Is time a dependent variable?
Time is a common independent variable, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.
How are independent variables varied?
In an experiment, the independent variable is the variable that is varied or manipulated by the researcher. … Here the independent variable is the dose and the dependent variable is the frequency/intensity of symptoms.
Is it OK to have multiple independent variables?
It is possible to have experiments in which you have multiple variables. There may be more than one dependent variable and/or independent variable. This is especially true if you are conducting an experiment with multiple stages or sets of procedures.
Is it okay to have two independent variables?
There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
What is independent variable and dependent variable examples?
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.
Why are dependent and independent variables not applicable in a descriptive type of research?
The independent variable is thought to be the cause whereas the dependent variable is thought to be the effect. … Descriptive studies only describe the current state of a variable, so there are no presumed cause or effects, therefore no independent and dependent variables.
What is the independent variable in this experiment?
An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable.
Why is independent variable important?
Dependent and independent variables are important because they drive the research process. As defined earlier, a variable as opposed to a constant is simply anything that can vary and that many researchers consistently look at the relationship between these two variables.
What is the use of independent variable?
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.
Which of the following best describes an independent variable?
The factor that’s changed by the experimenter and impacts the dependent variable best describes an independent variable.
Which of the following is a difference between independent variables and status variables?
Status variables are those that a researcher can manipulate as well as assign to a participant. in counseling research, all independent variables consist of only two conditions—treatment and no treatment.
How do you know if data is independent?
Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true. You can use the equation to check if events are independent; multiply the probabilities of the two events together to see if they equal the probability of them both happening together.
Identifying independent and dependent quantities from tables and graphs. … The quantity that depends on the other quantity is called the dependent variable, and the quantity it depends on is called the independent variable. The values of variables are used in tables and in plotting graphs.
What is a 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.
Is force dependent or independent?
On the other hand, if we consider a situation where the two variables namely force and acceleration of a moving body is taken in to account then acceleration depends upon force and accordingly, acceleration here is the dependent variable and force is the independent variable.
Is speed independent variable?
Independent variables are variables whose variations do not depend on another variable. … In this case, the non-variable is the distance covered, the independent variable is the speed while the dependent variable is the time which changes with respect to the change in the speed of the vehicle.
Why is time not on the y-axis?
Generally, time is always on the x-axis, because it allows for other quantities to be represented as functions of time, which is useful in physics. Time is also, in most cases, independent of other variables, which conventionally means that it should be on the x-axis.
