They're both parts of an experiment.
You conduct an experiment to find something out. Let's say you want to know if little kids like strawberries in their ice cream, and you know that little kids like ice cream. The presence of strawberries would be your manipulated variable. To test it, you would get two groups of kids - a control group that got normal ice cream (no strawberries, variable = 0 = false) and a group with ice cream that had strawberries (variable = 1 = true). You need the control group to help make sure nothing weird happened. For example, let's say you just happened to get a group of kids that hated ice cream. If you didn't have a control group, you would assume that no, kids don't like strawberries in their ice cream because none of them ate the ice cream when in fact it is the ice cream itself that they don't like, which you wouldn't've known without the control group.

What is a dependent variable independent variable and a control group?
The independent variable is the thing you change, the dependent variable is the variable that changes because of the independent variable, it could also be referred to as the effect, and the control group is the constant, the thing that stays the same and the variable that you compare your results to.
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).
What does the word manipulated variable mean?
A manipulated variable is essentially the same as an independent variable in the context of scientific research. Here's an example. Suppose you were studying how quickly rats can navigate a maze to find food and you wanted to know the effect of hunger level. You could keep one group of rats hungry for four hours and another group hungry for eight hours then allow each rat in the two groups to find its way through the same maze to a quantity of food. You would measure the time it took each rat to find the food. The manipulated variable would be the time that a rat had been kept hungry.
What characteristics must a problem possess in order for it to be studied scientifically?
It must have a control group, experimental group, and a experimental variable
In an experiment is the control group used to test the effect of the independent variable?
i dont know u tell me you dummy
What is one factor that differs between the control group and the experimental group?
The "independent" or "manipulated" variable is changed between the groups.
What is the difference between controlled or contrast and manipulated or tested variables?
A manipulated variable is the variable that has been changed in the experiment. A responding variable is the variable that has been kept through the whole experiment.
What is the purpose of the control group in a controlles experiment?
Experiments typically use control groups. One group of people are manipulated and measured, while the control group just stays as they are. The control group is measured against the manipulated group to see what changes.
What is the variable group and the control group?
it is when a bunch of variable are put together in a group.
What do you call a standard for comparison that helps to ensure that the experimental result is caused by the condition being tested?
a factor that changes in an experiment from manipulation of the independent variable is the
Does the control group get the variable?
No it does not
What is the differen ce between a control group and a variable group?
A control group is a group that does not receive the experimental treatment and is used as a baseline for comparison, while a variable group is a group that is exposed to the experimental treatment. The control group helps researchers determine the effect of the treatment by providing a reference point.
How are hypothesis test?
By collecting data. Hypotheses are tested through experimentation, which can be manifest in an infinite amount of ways. The common ground in all hypothesis testing is that both a control (a group that is free of experimental manipulation in the studied variable), and an experimental group (a group with one experimental variable manipulated to test the effect of this variable) are needed to understand the question raised in the hypothesis.
In an experiment the group that is exposed to the variable to be tested is called the?
control group
What is the name of the group is not exposed to the tested variable?
The Control Group is not exposed to the tested variable.
Which group is not subjected to the independent variable?
The Control(Controlled Variable)
Does the control group get the independent variable?
No it does not
