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.
What type of variable is a factor held constant to test the relative impact of the independent variable?
independent variables :):):):):):):):):):):):)
What dose controlled experiment mean?
this is an experiment that only one varible is manipulated at a time
What is ex-post-facto design?
Ex Post Facto (also called Causal Comparative Research) is useful whenever: • We have two groups which differ on an independent variable and we want to test hypotheses about differences on one or more dependent variables OR • We have two groups which already differ on a dependent variable and we want to test hypotheses about differences on one or more independent variables
What are Variables in an experament?
A variable of an experiment is anything that is changed either deliberately, or as a result of changing something else. An independent variable is one that is changed to obtain a different result. A dependent variable is the thing that changes as a result of changing the independent variable. There is also the controlled variable, or just control, which does not change throughout the experiment. A test or a trial
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.
Can you explain the relationship between independent and dependent variables within a hypothesis?
In a hypothesis, the independent variable is the factor that is manipulated or changed, while the dependent variable is the factor that is measured or observed to see how it is affected by the independent variable. The relationship between them is that changes in the independent variable are believed to cause changes in the dependent variable, allowing researchers to test their hypothesis and draw conclusions.
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.
What changes during a controlled experiment?
In a controlled experiment, only the independent variable is intentionally changed to test its impact on the dependent variable. All other variables are kept constant to ensure that any observed effects are due to the manipulated variable. This control allows researchers to isolate the relationship between the independent and dependent variables.
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 affect does salt to freezing point hypothesis indipendent and dependent variable?
The independent variable is the amount of salt, while the dependent variable is the freezing point of the solution. By increasing the amount of salt (independent variable), the freezing point (dependent variable) of the solution decreases, following the colligative properties of solutions.
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.
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?
independent variables :):):):):):):):):):):):)
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 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.
