What controlled variables in science?
The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.
How many variables should you have when you start an experiment?
An experiment involves three types of variable.The independent variable is the one you are investigating. It is the one which you deliberately vary in the experiment. You should only have one independent variable.The dependent variable is the variable which you measure to get your results. Often there is only a single dependent variable but there can be more.All other variables must be controlled ie kept constant so they do not change the result. There are usually many control variables in an experiment.
Where do you find the independent variable in data table?
If x depends on a, b and c, then x is the dependent variable, and a, b, and c are the independent variables - you can vary them at will, and x depends on them. Often it appears on the right hand side of an equation, such as x = a +b + 2/c, showing how x depends on the independent variables.
Can there be more than one independent variables in a experiment?
In general yes. But it really depends on the experiment. If you want to know if it hurts to punch a wall, you don't need an independent variable (unless you want to compare the magnitudes of the pain). But for school experiments, most of the time, if not all of the time. Yes.
For economists substitutes for laboratory experiments often come in the form of?
natural experiments offered by history or untested theories
Can independent variables be changed?
Yes. In fact, in multiple regression, that is often part of the analysis. You can add or remove independent variables to the model so as to get the best fit between what values are observed for the dependent variable and what the model predicts for the given set of independent variables.
Ecologists often use mathematical models and computer simulations because?
these approaches allow them to study the interactions of multiple variables and simulate large-scale experiments.

What is an Example of two independent variables?
Variables are symbols that replace unknown numbers. Variables are often letters. For example: 5*x=10 7*6=y Here "x" and "y" are the variables.
What is a Cartesian graph used for?
To illustrate the relationship between one or more dependent variables and a variable (often an independent variable).
What should be the only independent variable?
In most real life cases, limiting an experiment to only one independent variable makes the whole experiment a waste of time. More often than not there are several independent variables.
Why is argon often a good choice for these experiments?
The answer will depend on what "these" experiments are!
What do you call variable that is manipulated by experiments when conducting a experiment?
Interestingly, it is often called the manipulated variable, though it is also called the independent variable and sometimes other names.
How are dependent and independent variables used in an experiment?
An independent variable is the variable that was changed. The dependant is what was measured. Eg. If you filled 3 cups of water - one with 1/4 of a cup, one with half a cup and one with 3/4 of a cup. Then you grab a spoon to find the highest note, then the amount of water is the independent variable and the sound is the dependant.
What do scientists often do to reduce the effects of uncontrollable variables?
Scientists often use control groups, randomization, and blinding techniques to reduce the effects of uncontrollable variables in their experiments. Control groups help establish a baseline for comparison, randomization helps minimize bias, and blinding techniques prevent researchers and participants from being influenced by their expectations.
