Why does an investigator change only one variable in an experiment?
So the variable can be at constant.
Why does the investigator in an experiment change only one variable?
the investigator only changes one variable in an experiment because they need to see how that one variable reacts. if you wanted to see how the dependent variable changed but changed the independent variable you would not see how the one variable reacts.
What is the dependent variable of the experiment?
Dependent Variable: - Something that might be effected by the change in the independent variable - What is observed - What is measured - The data collected during the investigation :)
If your manipulated variable causes a change what is the change called?
A Dependent Variable!
What do you call the variable in an experiment that do not change?
Control Variable
Why does an investigator change the value of a variable parameter during in investigation?
Which factor does the investigator change during an investigation?
What the investigator varies in the experiment such as time?
A parameter in an experiment that can change is known as a variable.
Why does an investigator change only one variable in an experiment?
So the variable can be at constant.
What is the difference between a controlled parameter and a variable parameter?
controlled parameters the factor that stays the same in ALL groups variable parameters the factor(s) that change between control groups and variable groups
Why is only variable changed in an investigation?
You only change one variable in an investigation because if you change more than one you won't know which change affected the data.
Why does the investigator in an experiment change only one variable?
the investigator only changes one variable in an experiment because they need to see how that one variable reacts. if you wanted to see how the dependent variable changed but changed the independent variable you would not see how the one variable reacts.
What variable must he change in order to complete his investigation?
Amount of water
What independent variable mean?
When conducting scientific experiments, the researcher manipulates an "independent variable" (i.e., some physical parameter that can be controlled) in order to measure the effects of such manipulation on a "dependent variable" (i.e., the results of changing the physical parameter of interest). For example, one could lower the temperature in a refrigerator (the temperature being an independent variable) and wait to observe when water left in the refrigerator turns to ice (the change from liquid water to the solid form being the dependent variable). Thus, the change in the dependent variable depends on the manipulation of the independent variable. The independent variable is the variable you change, the dependant variable is what changes as a result of what you change.

What is the scientific definition of an independent variable?
An independent variable is not affected by the change of another independent variable. To make an experiment, you generally try to change each independent variable in its turn, leaving other independent variables constant, getting the result (the dependent variable) which was chosen. The results can be exhibited as graphs, where the independent variable serves as abscissa or a parameter, or tables
What is the difference between a manipulated and responding variable?
Manipulated variables are also known as independent variables. These are the variable which you change in an investigation. Plotted on the x axis.
