The goal of using replication control randomization and blindness in experimental design is to compeletey eliminate bias from an experiment?
False
What is scientific bias and how do you avoid it?
There are numerous biases (e.g., knowing which subjects are assigned to which experimental groups). Most can be avoided by using proper Control procedures (e.g., using a double-blind design) and using proper control groups.
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
The group of experimental subjects which is left natural or left unchanged is called the?
experimental group
In an experiment a group that is identical to a control group except for one factor and that is compared with the control group?
a controlled experiment is an experiment that tests only one factor at a time by using a control group and 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.
The goal of using replication control randomization and blindness in experimental design is to compeletey eliminate bias from an experiment?
False
What is used as a way to compare values for a dependent variables in many experiments?
experimental control
What is scientific bias and how do you avoid it?
There are numerous biases (e.g., knowing which subjects are assigned to which experimental groups). Most can be avoided by using proper Control procedures (e.g., using a double-blind design) and using proper control groups.
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.
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
Does a control group receive experimental treatment?
the control group does not receive receive an experimental treatment but stay in the same environment.
