What is is an independent variable?
An independent variable is the variable that the scientist changes, and the dependent variables are the variables that the scientist doesn't control. So that would mean that the independent variable is typically the variable being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated. The independent variable in a science experiment is the variable that you change on purpose. The independent variable is the variable that scientists manipulate in an experiment in order to determine its effect on a dependent variable. For example, if you wanted to see what affected frog deformities, you would set up an experiment where you would have frogs placed in the same environments as each other, except for one variable (independent) that is different. Let's say the control group gets exposed to all the same food, temperature, length of daylight, population density, etc., as the experimental group. The experimental group has the amount of UV exposure varied. The UV exposure (independent variable) would be used to determine its effects on frog deformities (dependent variable).
Why do all of the parameters except the independent variable have to be cntrolled?
Controlling all parameters except the independent variable is essential to isolate the effects of the independent variable on the dependent variable. This ensures that any changes observed in the dependent variable can be attributed solely to the manipulation of the independent variable, thereby enhancing the validity and reliability of the experiment. Without controlling these parameters, confounding variables could introduce bias and lead to inaccurate conclusions.
Why is it importantthat all variables in an expiriment except for the independent variable are controlled?
Because otherwise it will not be possible to know whether observed variations in the dependent variable are due to one independent variable or another.
What makes a function linear?
Neither variable appears anywhere in the equation in a denominator, or raised to any power except the first power.
(h plus j) - ef?
The numerical value will depend on the values of each variable. The expression can't be further simplified, except that the parentheses can be omitted.
Sample treated like other experimental groups except variable is not applied?
Control Variable♪☆
What Sample is treated like other experimental groups except the variable is not applied?
The control group.
What is the sample treated like other experimental groups except the variable is not applied?
The control group.
A sample that is treated exactly like the other experimental groups except that the variable is not applied to it?
A control group.
What is a sample treated like other experimental groups except that the variable is not applied?
A sample treated like other experimental groups except that the variable is not applied is known as a control group. The control group serves as a baseline to compare the effects of the experimental variable on the treatment group. By not applying the variable, researchers can isolate its effects and determine if any observed changes in the experimental group are due to the variable itself. This helps ensure the validity of the experimental results.
What is a control group for a science fair project with stains and detergent?
a control group is a sample that is treated like the other experimental groups except that the independent variable isn't applied to it
What conditions must be met if you want to have a scientifically valid sample for a study?
You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.
How does a psychologist use an independent variable in an experiment?
you have to decipher out what exactly it is saying buut... participants that are exposed to the independent variable are in the experimental group and the participants who are treated the same way as the experimental group, except that they are not exposed to the independent variable, make up the control group... any...

Control and experimental groups are identical except for the?
Independent variable
What is the part of an experiment that is treated just like the experimental group except for the one factor being tested?
The control group is the part of an experiment that is treated just like the experimental group, except it does not receive the treatment or factor being tested. It serves as a baseline for comparison to evaluate the true effects of the treatment.
What do you call the variable that must remain the same between two groups?
The variables that must remain the same between the control group and experimental group is are called controlled variables, and include everything except the experimental variable.
