Why can't you draw a conclusion about the effect of one variable in an experiment when the others are not controlled?

If you have multiple uncontrolled variables, you can't tell which one (or which combination) is causing the change. For example, if you put four different random chemicals in milk and it exploded, you wouldn't know which of the four chemicals makes milk explode, or if it takes a combination of those four chemicals to cause the explosion.

What is a controlled variable in an experiment?
controlled variable is the factor that leaved unchanged to investigate any only one factor that has been changed in the other experiment and the effect of not altering this factor.
What is an experiment that involves changing one factor and observing its effect on another while keeping all other factors constant?
Controlled experiment. The thing you change is called the independent variable and the constants are the dependent variables. By only changing the independent variable, any results can be attributed to this.
Within the framework of an experiment how do you describe the independent variable dependent variable and the controlled variables?
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.
What is controlled in a controlled study?
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group. A control experiment is designed to check or correct the results of a previous experiment. It does this by removing the variable or variables operating in the other experiment. The comparison obtained is an indication or measurement of the effect of the variables concerned
The factor being measure in an experiment?
The dependent variable is monitored as the independent variable is changed. One is testing the effect of the independent variable on the dependent variable (ie effect of dissolved HClO on pH).
What are the main parts of of a controlled experiment?
The main parts of a controlled experiment are the dependent variable and the independent variable. The dependent variable is what is measured in the experiment. The independent variable is the variable that is varied or manipulated by the researcher. The independent variable is the presumed cause, whereas the dependent variable is the presumed effect.
What is the point of a controlled experiment?
The point of a controlled experiment is to assess the effect of one variable in a life process. This could also be for a chemical process.
What is a controlled variable in an experiment?
controlled variable is the factor that leaved unchanged to investigate any only one factor that has been changed in the other experiment and the effect of not altering this factor.
Does A controlled experiment measures the effect of one variable?
Yes, that's the precise definition of a scientific experiment.
What does a variable stand for in math?
A variable is a very important thing when you are doing an experiment. These are things that have an effect on the experiment. There are three categories of variables in math:The controlled variable: variable the never changesThe manipulated variable: variable that does changeThe responding variable: the result of the experiment
What is control in an experiment?
Controlled experiments are used to investigate the effect of a variable on a particular system.
What is an experiment that involves changing one factor and observing its effect on another while keeping all other factors constant?
Controlled experiment. The thing you change is called the independent variable and the constants are the dependent variables. By only changing the independent variable, any results can be attributed to this.
In an experiment what are the controlled variables?
The variable YOU change which will in turn effect another variable (the dependent variable). The controlled variable is plotted on the x - axis of a graph.
Within the framework of an experiment how do you describe the independent variable dependent variable and the controlled variables?
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.
What is a controlable variable?
A variable which can be controlled by some other variables or some other parameters is known as controlled variable. A controlled variable is something that can be changed by the experimenter. It is also known as the independent variable. It is something that gives a measure by which to gauge everything else by. For example, if you were testing the effectiveness of a plant fertilizer the "control" would be a plant that is given no fertilizer at all. A controlled variable is the variable that stays the same through out the experiment meaning no changes to it.
What is controlled in a controlled study?
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group. A control experiment is designed to check or correct the results of a previous experiment. It does this by removing the variable or variables operating in the other experiment. The comparison obtained is an indication or measurement of the effect of the variables concerned
Why cant you draw a conclusion about the effect of one variable in an investigation when the other key variables are not controlled?
If none of the variables are constant (or controls) you have no idea which variable or combination of variables caused the effect.
