What does controlled experiment mean in science terms?
All science experiments are performed in a controlled manner which means, there will be a positive control, a negative control and importantly the subject sample(s) who's behavior is not known. The experimental observation must be positive with the positive control sample and negative with the negative control sample, no matter whatever the condition is. Only in this set up the result of a subject (which is the actual unknown experimental sample) would be considered as a faithful result.Any fault or irregularities of the controls will destroy the authenticity of an experiment.
What is the relationship between Control and experimental groups?
control groups are those which you keep constant you don't do anything to them and experimental groups are the ones which you are adding something to it to see what happens
In an experiment the group that is exposed to the variable to be tested is called the?
control group
What is the role of positive control in an experiment?
a control group is a group where nothing is changed. the experimental group is where you change one factor two examples: experimental group: 3 cups vinegar, 1 tablespoon baking soda, 5 drops food coloring control group: 2 cups vinegar, 1 tablespoon baking soda, 5 drops food coloring experimental group: plants with 4 hours of sunlight, 1/2 cup water every other day, fertilizer, warm room control group: plants with 4 hours of sunlight, 1/4 cup water every single day, fertilizer, warm room
The group of experimental subjects which is left natural or left unchanged is called the?
experimental group
Which term describes a type of independent variable used to compare differences in dependent varables?
experimental control
Why is experimental control needed in experiments?
The experimental control is what you compare your experimental data with. Without the control, you can't tell if the variable you are testing is what is causing your results.
What is an experimental control?
A group of experimental subjects that is not exposed to a chemical or treatment being investigated so that it can be compared with experimental groups that are exposed to the chemical or treatment. cw: An experimental control may be the control group. In general, the experimental control is something that allows you to say that the treatment effects on the experimental group are due to the treatments, rather than anything else.
What is used as a way to compare values for a dependent variables in many experiments?
experimental control
What do you call an experimental setup in which the experimental variable is missing?
control setup
How is a quasi-experimental design different from a pure experimental design?
pure -absolute control Quasi -have some control
What does control as an experiment means?
A control sample or control group is used to compare with the experimental group or sample. The control sample ideally, should be exactly the same as the experimental sample except that you don't give your experimental treatment to the control sample. Afterwards you compare the 2 samples to see if your experimental treatment had any kind of effect. The control is like a reference point.

Does a control group receive experimental treatment?
No, a control group does not receive the experimental treatment. It is used as a baseline to compare the effects of the treatment or intervention being tested in the experimental group.
What is the difference between control and experimental variables?
Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
What is the difference between a control groups and experimental groups?
The control is a group that is held constant and is not experimented with, The experimental group is the group that is experimented with
