Imagine you're doing an experiment in which you want to see the effect of an hormone in a cell culture. You have to control (know the values of the properties you are experimenting in) things like temperature, nutrient concentration, pH (acidity), etc.
If you want to know if this hormone you are testing actually affects your cell culture, you must only vary this variable (e.g. hormone concentration mass/volume). If you, instead, change hormone concentration and pH, you may not be entirely sure if the effect you looked in your cell culture was caused by the hormone concentration or the pH.
So, regardless methodological discipline, you can only vary one variable at a time.
What else can I help you with?
What is the one variable A change in an experiment to test a hypothesis?
Manipulated variable
What is one variable that is change in an experiment to test a hypothesis?
Manipulated variable
What are factors that can change an experiment in which only one variable is manipulated at a time?
um varible i think now
An experiment in which only one variable the manipulated variable is changed at a time is called?
Controlled
Experiment in which only one variable the manipulated variable is changed at a time is?
A controlled experiment is when only one variable, the manipulated variable, is changed at a time to observe its effect on the dependent variable, while keeping all other variables constant. This approach helps to determine the specific impact of the manipulated variable on the outcome of the experiment.
Why must a controlled experiment have one manipulated variable?
a controlled experiment must have only one manipulated variable becuase if the experiment had multiple manipulated variables then it would not be a controlled experiment anymore it would be a manipulated Deseret experiment
What is an experiment in which only one variable is manipulated variable at a time?
Controlled Experiment :Pcontrolled experiment.
An experiment in which only one Variable is manipulated at a time?
Controlled experiment
What is manipulated variables and responding variables?
Manipulated variables: what you change in the experiment on purpose. Can be one thing. Ex: The color of the Popsicle.Responding variables: The thing that changes because of the manipulated variable. What changed because you changed something.Ex: The rate of speed at which the Popsicles melt.
What is responding valuable?
Do you mean "responding variable"? In a scientific investigation, you try to change only one thing to see what happens. The thing you change is the manipulated variable (also called the independent variable). The result of this change is the responding variable (also called the dependent variable). For example, what if you measure the temperature of a beaker of water, then put it in the refrigerator for 24 hours, then measure again. The change in the temperature from the room to the fridge is the manipulated variable (you controlled it). Any change in the water temperature is the responding variable. It responded to the change you made.
What is an experiment in which only one variable the manipulated variable is changed at a time is called an?
An experiment in which only one variable, the manipulated variable, is changed at a time is called a controlled experiment. This approach allows researchers to isolate the effects of the manipulated variable on the dependent variable, ensuring that any observed changes can be attributed directly to the variable being tested. By keeping all other variables constant, the reliability and validity of the results are enhanced.
How can AN EXPERIMENT that disproves a hypothesis be used?
by the variables. The variables are manipulated and responding. the manipulated ones are the one that is changed in the experiment. the responding variable is the one who is expected to change.
