What is the function of a control in a scientific investigation?
You establish a controlled variable from which you can compare your results from your experimental variables.
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
Variables that do not change in a experiment?
the dependant variable
What is A baseline for an experimental investigation is provided by the?
Control Group
Why is it harder to control variables in the field than the laboratory?
you have control in a laboratory

What do you call the variable in an experiment that do not change?
Control Variable
What dependent independent and control variables are in an investigation?
The answer depends on the nature of the investigation.The answer depends on the nature of the investigation.The answer depends on the nature of the investigation.The answer depends on the nature of the investigation.
What variables stays the same?
In an experiment, variables that stay the same are known as constants or control variables. These are factors that are kept consistent to ensure that any changes observed in the study are due to the variable being tested and not other factors. Control variables help maintain the validity and reliability of the experiment.
How many independent variables should an investigation have?
There can only be one independent and one dependent variable. All other variables should be classed as control variables and must be kept constant to achieve a fair test.
What variables don't change in an experiment?
In an experiment, the variables that do not change are called constants or control variables. These are aspects of the experiment that are kept consistent and not altered, providing a baseline for comparison with the variable being tested. By controlling these factors, researchers can isolate the effects of the variable they are studying.
When was a control used in the investigation of the amphipods and sea butterflies Why was a control necessary?
A control was used in the investigation of amphipods and sea butterflies to provide a baseline for comparison. By having a control group of organisms that were not exposed to the same conditions as the experimental group, researchers were able to measure the effects of the specific variables being tested. This helps to determine if changes observed in the experimental group were due to the variables being studied or other factors.
What variables do not change during an experiment?
Constants, also known as control variables, do not change during an experiment. These variables are kept consistent to ensure that the only factor being tested is the independent variable. Examples of constants include temperature, pressure, and time.
What is a variable unchanged in an experiment?
A variable that is kept constant and not changed throughout an experiment is called a control variable. Control variables help ensure that any changes observed in the experiment are due to the manipulated variables and not other factors.
What is the definition of a control variable?
Variables are simply names used to refer to some location in memory - a location that holds a value with which we are working. It may help to think of variables as a placeholder for a value. in system
What is the difference between control and experimental variables?
Control variables are kept constant throughout an experiment to ensure that any changes in the dependent variable are due to the manipulation of the independent variable. Experimental variables, on the other hand, are the factors that are deliberately changed by the researcher to observe their effect on the dependent variable.
Is it easier to control dependent variables than independent variables in a scientific experiment?
It is easier to control independent variables
