What is a control treatment in biology?
In a scientific study, a control group is used to establish a cause-and-effect relationship by isolating the effect of an independent variable. Researchers change the independent variable in the treatment group and keep it constant in the control group. Then they compare the results of these groups.Dec 15, 2021
What are two types of control treatments?
Types of Control Groups in Medical Experiments No treatment concurrent control: one group is given the treatment, the other group is given nothing. Active treatment concurrent control: one group is given the treatment, the other group is given an existing therapy that is known to be effective.Oct 1, 2015

When conducting an experiment, a control is an element that remains unchanged or unaffected by other variables. It is used as a benchmark or a point of comparison against which other test results are measured.Jun 9, 2021
What is a control group biology?
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results.Jan 29, 2020
What does treatment mean in research?
Treatment groups are the sets of participants in a research study that are exposed to some manipulation or intentional change in the independent variable of interest. They are an integral part of experimental research design that helps to measure effects as well as establish causality.Dec 19, 2018
Is a control group a treatment?
In the design of experiments, treatments are applied to experimental units in a treatment group. In comparative experiments, members of a control group receive a standard treatment, a placebo, or no treatment at all. There may be more than one treatment group, more than one control group, or both.
What is an example of a control in an experiment?
An example of a control in science would be cells that get no treatment in an experiment. Say there is a scientist testing how a new drug causes cells to grow. One group, the experimental group would receive the drug and the other would receive a placebo. The group that received the placebo is the control group.Nov 19, 2021
What is the difference between a control treatment and a control group?

Why is a control condition important?
Thus, including a control condition allows researchers to compare the way things are in the presence of an independent variable with the way things would have been in the absence of an independent variable.
Why do we need a control group to demonstrate the effectiveness of a treatment?
The control group consists of elements that present exactly the same characteristics of the experimental group, except for the variable applied to the latter. This group of scientific control enables the experimental study of one variable at a time, and it is an essential part of the scientific method.
What happens if your control group differs from the treatment group?
If your control group differs from the treatment group in ways that you haven’t accounted for, your results may reflect the interference of confounding variables instead of your independent variable.
What does it mean to use a control group?
Then they compare the results of these groups. Using a control group means that any change in the dependent variable can be attributed to the independent variable.
How to reduce confounding variables?
There are several methods you can use to decrease the impact of confounding variables on your research: restriction, matching, statistical control and randomization. In restriction, you restrict your sample by only including certain subjects that have the same values of potential confounding variables.
What is quasi-experimental design?
While true experiments rely on random assignment to the treatment or control groups, quasi-experimental design uses some criterion other than randomization to assign people. Often, these assignments are not controlled by researchers, but are pre-existing groups that have received different treatments.
How to test the effectiveness of a pill?
To test its effectiveness, you run an experiment with a treatment and two control groups. The treatment group gets the new pill. Control group 1 gets an identical-looking sugar pill (a placebo) Control group 2 gets a pill already approved to treat high blood pressure. Since the only variable that differs between the three groups is the type ...
What is treatment in research?
The treatment is any independent variable manipulated by the experimenters, and its exact form depends on the type of research being performed. In a medical trial, it might be a new drug or therapy. In public policy studies, it could be a new social policy that some receive and not others.
What is the treatment group?
The treatment group (also called the experimental group) receives the treatment whose effect the researcher is interested in. The control group receives either no treatment, a standard treatment whose effect is already known, or a placebo (a fake treatment). The treatment is any independent variable manipulated by the experimenters, ...
What is an example of a proposed biological control of one HAB species by another?
One example of a proposed biological control of one HAB species by another is the potential use of Amoebophyra, which is a syndinian parasite that infects several species of free-living dinoflagellates that cause HABs, including Alexandrium.
How to control HABs?
The oldest and most widely used approach to controlling HABs involves the application of a certain types of clay during blooms. When sprinkled on surface waters during an algal bloom, the tiny but dense clay particles will “flocculate” or combine with other particles in the water, including the HAB cells.
What is the clay used for in South Korea?
Today, both South Korea and China routinely use clay to control algal blooms. In South Korea a clay called “yellow loess” has been used since 1996 to control blooms of a HAB species called Margalefidinium polykrikoides that have caused millions of dollars of damage to fish farms. Many environmental studies conducted in South Korea have produced no ...
What is the preferred management strategy for HABs?
There is a general consensus that prevention is the preferred management strategy for HABs, but this management strategy can be difficult to implement, and there are presently few active efforts aimed at directly preventing blooms. A growing field of research is focused on methods and technologies to control or suppress blooms.
Does clay kill algae?
In deeper water, darkness, prolonged contact with the clay, and eventual burial in sediments on the seafloor can also kill the algae cells. The practice of using clay to control algal blooms in the ocean is not new, with mentions in scientific literature dating back 30 years or more. Today, both South Korea and China routinely use clay ...

Control Groups in Experiments
- Control groups are essential to experimental design. When researchers are interested in the impact of a new treatment, they randomly divide their study participants into at least two groups: 1. The treatment group (also called the experimental group) receives the treatment whose effect the researcher is interested in. 2. The control groupreceives e...
Control Groups in Non-Experimental Research
- Although control groups are more common in experimental research, they can be used in other types of research too. Researchers generally rely on non-experimental control groups in two cases: quasi-experimental or matching design.
Importance of Control Groups
- Control groups help ensure the internal validityof your research. You might see a difference over time in your dependent variable in your treatment group. However, without a control group, it is difficult to know whether the change has arisen from the treatment. It is possible that the change is due to some other variables. If you use a control group that is identical in every other way to t…
