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.
Which of the following terms describes a variable that is controlled by the experimenter?
The term that describes a variable controlled by the experimenter is the "independent variable." This variable is manipulated to observe its effect on another variable, known as the dependent variable, which is measured in the experiment. By controlling the independent variable, the experimenter can establish cause-and-effect relationships in their research.
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 variable is controlled by an experimenter?
The variable controlled by an experimenter is known as the independent variable. This is the factor that the experimenter manipulates in order to observe its effect on the dependent variable, which is the outcome being measured. By controlling the independent variable, the experimenter can determine causal relationships in the experiment.
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.
A controlled experiment allows the scientist to isolate and test?
A controlled experiment allows the scientist to isolate and test a specific variable by keeping all other variables constant. This helps to determine the direct impact of the variable being tested on the outcome of the experiment. Controlled experiments are essential for establishing cause-and-effect relationships in scientific research.
Does a controlled experiment have only one variable?
No, a controlled experiment can have more than one variable. However, in a controlled experiment, only one variable is intentionally changed (independent variable) to observe its effect on another variable (dependent variable), while all other variables are kept constant (controlled variables) to ensure the validity of the results.
An experiment in which only one variable is manipulated at a time is called?
A controlled experiment. In a controlled experiment, one variable (independent variable) is changed or manipulated while all other variables are kept constant to observe the effect on the dependent variable. This allows researchers to determine the specific impact of the variable being tested.
The one factor that differs in a controlled experiment?
In a controlled experiment, the one factor that differs is the independent variable. This is the variable that is deliberately changed or manipulated by the researcher in order to observe its effect on the dependent variable. The goal of a controlled experiment is to isolate the impact of the independent variable on the dependent variable while holding all other variables constant.
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 the independent and dependent groups of an controlled experiment?
In a controlled experiment, the independent variable is the variable that is deliberately changed or manipulated by the researcher to observe its effect on the dependent variable. The dependent variable is the variable that is observed and measured in response to changes in the independent variable. The independent variable is controlled by the researcher, while the dependent variable is the outcome that is measured.
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 the part of the experiment that is changed and tested?
The part of the experiment that is changed and tested is called the independent variable. This variable is manipulated or controlled by the researcher to observe its effect on the dependent variable.
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.
What is a controlled factor in an experiment?
A controlled factor in an experiment is a variable that is kept constant or unchanged throughout the experiment. By controlling these factors, researchers can isolate the effect of the independent variable on the dependent variable. This helps ensure that any changes observed are due to the manipulated variable and not other factors.
The factor a scientist changes in a controlled experiment is the?
The factor a scientist changes in a controlled experiment is called the independent variable. It is the variable that is deliberately manipulated or varied by the scientist to observe its effect on the dependent variable.
