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 else can I help you with?
How many variables should an experiment test at a time?
It is usually recommended to test one variable at a time in an experiment to accurately determine its effect. This helps to isolate the impact of that specific variable and avoid confounding results from multiple factors changing simultaneously.
How many variables can be tested at a time?
An experiment should test only one variable (the independent variable) at a time. If you are testing more than one variable at a time, you have no idea which variable is causing which effect.
What is the one variable that is changed to test a hypothesis is?
The one variable that is purposely changed to test a hypothesis is manipulated variable
What is a scientist that carries out series of test that are identical in every respect for one factor which is the manipulated variabe?
In a(n) MULTI VARIABLE, a scientist carries out a series of tests that are identical in every respect except for one factor , which is the munipulated variable. I got this example from my WKST at Pearson Successnet.com
Why is it advantageous for a scientist a test only one variable at a time during an experiment?
If you change more than one variable at a time, you will not be able to tell which variable is responsible for what change. Scientists need to know exactly which variable caused the observed experimental results.It is advantageous for scientists to test only one variable at a time during an experiment because if you change all variables at once, you will not be able to tell which variable is responsible for the observed results.
What is test variable mean in science?
the test variable is the independent variable.
The one factor that a scientist changes during an experiment also called independent variable?
Yes, the one factor that a scientist changes during an experiment is also called an independent variable.
What does a scientist change in his experiment?
One variable at a time.
What does a scientist change in a experiment?
One variable at a time.

The one variable that is purposely changed to test a hypothesis is?
manipulated variable!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What is the one variable that is changed in an experiment to test a hypothesis?
The one variable that is changed in an experiment to test a hypothesis is called the independent variable. This is the variable that the researcher manipulates or controls to observe its effect on another variable, known as the dependent variable.
