How do the test variables and outcome variables in an experiment compare?
Test variables are the factors that are intentionally changed or manipulated by the researcher in an experiment, whereas outcome variables are the factors that are measured and affected by the test variables. Test variables are the independent variables that are controlled by the researcher, while outcome variables are the dependent variables that change in response to the test variables. The relationship between the test variables and outcome variables is explored to determine the effect of the test variables on the outcome variables.
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).
A controlled experiment allows the scientist to isolate and test what?
to isolate and test single variables
How many variables does a controlled experiment test?
As many as you need. You can't change more than one if you want accurate results.
How many variables does a controlled experiment have?
An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.
What variables did Galileo test when he conducted his pendulum experiment?
he sucked balls and he was gay
How many variables are generally tested in an experiment?
The trick to designing a good experiment is to figure out a way for it to test the effects of only one variable, and to avoid any effects of others.
When a experiment only has one variable that can change and all other variables are kept unchanged this type of experiment is an?
it is a fair test
How many variables are kept constant in a experiment?
All variables except one, the experimental variable, are kept constant in an experiment.
What is the difference between a test and an experiment?
A test is used to determine the performance, reliability, or function of something, while an experiment is a controlled procedure undertaken to discover, test, or demonstrate something. In a test, variables are usually kept constant, whereas in an experiment, variables are intentionally changed to observe their effect.
How many manipulated variables can you have in an experiment?
1
How many variables there be in an experiment?
As few as possible.
