Independent variable is what you change in the experiment group.

Dependent variable is what happens because of the independent variable. It has to be measurable in degrees, inches, or other such measurements.

How do the test variables (independent variables) and outcome variables (dependent variables) in an experiment compare?

The test variable (independent variable) controls the outcome variable (dependent variable).


Which variable is the one variable that is purposley changed to test a hypothesis?

The independent variable is the one that is purposely changed to test a hypothesis.There are 3 kinds of variables in a scientific experiment: independent, dependent, and controlled.


What is the definition of an independent and dependent variable?

A independent variable is a particular variable that is being manipulated and the dependent variable is the result of the change of the independent variable. Ex. In an experiment the independent variable is what is being tested and the dependent variable is the result of the test.


How many independent variables should an investigation have?

There can only be one independent and one dependent variable. All other variables should be classed as control variables and must be kept constant to achieve a fair test.


What is an independent variable and dependent variable?

Question: What's a variable?Answer: A variable is an object, event, idea, feeling, time period, or any other type of category you are trying to measure. There are two types of variables-independent and dependent.Question: What's an independent variable?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. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age. In fact, when you are looking for some kind of relationship between variables you are trying to see if the independent variable causes some kind of change in the other variables, or dependent variables.Question: What's a dependent variable?Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. 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. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of the two variables you are using in this sentence in they way that makes the most sense. Then you can figure out which is the independent variable and which is the dependent variable:(Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable).For example:(Time Spent Studying) causes a change in (Test Score) and it isn't possible that (Test Score) could cause a change in (Time Spent Studying).We see that "Time Spent Studying" must be the independent variable and "Test Score" must be the dependent variable because the sentence doesn't make sense the other way around.


What are the types of variables?

THE TYPES OF VARIABLES1.Constant or Controlling Variablesvariables that you do not change all throughout the experiment.2.Manipulated Variablevariable that you change in the activity.They are also called the Independent Variable3.Responding Variablevariable that result by changing the variablealso called as the Dependent Variable in doing such activity ,Far Test can be achieve by changing only one variable at a time.


What type of variable is a factor held constant to test the relative impact of the independent variable?

An variable is changed to determine how it will affect the dependent variable?

The type of variable that responds to the dependent variable is called the independent variable.


How do scientist usually test for one variable?

To test a single variable, scientists will change only that one variable (called the independent variable) whilst keeping everything else that could possibly affect the results of the experiment exactly the same. The other variables that are affected by the independent variable changing (called dependent variables) are then measured, and a conclusion can be made.


What affect does salt to freezing point hypothesis indipendent and dependent variable?

An "hypothesis" doesn't have independent and dependent variables until you design an experiment to test it. If you want to test the effect that salt in solution has on the freezing point of the solution, then the independent variable is the presence, absence, or concentration of the salt. The dependent variable is the freezing temperature you measure in each condition.


How do you test one independent variable and one dependent variable?

In an equation like y = mx + b, such as y = 3x + 2, x is the independent - YOU put in the x. y is the ANSWER you get, depending on what you used for x. To test, do exactly that - you choose what to do for your independent variable, and see what happens for the y. Works for both math and science. Change the independent variable, and compare how your dependent variables change depending on what changes you made to the independent.


What dose controlled experiment mean?
