What is the one factor that is different between the control group and the experimental group?

By definition, the control group is what the experimental group is measured against. For example, if one is doing an experiment to measure the effect of a drug on blood pressure, the experimental group would receive the drug and the control group would receive the placebo, or blank. The blood pressure of both groups would be measured after ingestion of either the drug or placebo and any differences in blood pressure we would attribute to the effect of the drug. Care must be taken, however, that the two groups are as identical as possible and that all procedures are carried out identically. Furthermore, to eliminate even more bias, both the researchers and the experimental subjects would not know whether they were receiving drug or placebo (a double-blind study).

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 factor tested in an experiment called?
Which group in am controlled experiment is not exposed to the experimental variable
What is the part of an experiment that is treated just like the experimental group except for the one factor being tested?
Im in 7th grade and i learned it like 3 years ago. its the variable.
What is the difference between relative retention time and retention time?
the difference between retention time and retention factor is that the retention time is a quatitative value where`s the retention factor is a qualitative on.
What is the limiting factor in the reaction of hydrochloric acid and magnesium?
the limiting factor varies between the magnesium and hydrochloric acid as there needs to be enough hydrogen for every magnesium..
What factor is kept the same between the control and experimental groups is called?
A factor that is kept the same between the control and experimental groups is called
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 a factor in a experiment that you measure to gather results?
It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.
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
Why is the control and experimental group needed for an experiment?
The control group is necessary to know if the factor being tested is making a difference in the experimental group. Both should be subject to the same conditions, except for the one condition or factor being tested on the experimental group. Differences between the outcomes of the two groups, good or bad, can then be attributed to the one factor that is different. Without the control, it would be most difficult to tell what the factor being tested had done, because it's not really possible to tell what would have happened without it.
What is cofounding factor in epidemiology?
confounding factor is defined as the hidden or the factor which distorts the the experimental unit since it difficult to control ,but in case of epidemiology , the factor that alawys involve in experimental and observational study , which is emphasized or focused on life.
Which factor distinguishes experimental group from control group?
In an experimental design comparing two groups in which one group gets one treatment and another group gets a second treatment, the experimental group is the group with the "different" treatment. The control is the "usual" treatment; the experimental group gets the "new" treatment. Of course, things get complicated with more complicated "experiments."
Why is experimental design a key factor in science inquiry?
The experimental design is always a key factor in the science inquiry. The experimental design shows the methods that lead to the science.
What is the difference between factor and treatment in a experiment?
treatment is a factor in which a researcher will apply to an experimental unit and collect the data from the same. factor is a material used by researcher in an experiment in the field .
Factorial Designs and interactions?
They are an important aspect of experimental design when you have two (or more) explanatory factors are different levels and the effect of the factors may be different from simply the sum of the effects of each factor separately - because of interaction between factors.
An experiment that test only one factor at a time by using a comparison of a control group with an experimental group?
A variable test?
What is a contolled experiment?
A scientific investigation in which both the control group and experimental group(s) are kept under similarvariables apart from the factor under study so that the effect or influence of that factor can be identified or determined.
