If the mussels in the experimental group died, the students would know that whatever condition or factor being tested in the experiment had a detrimental effect on the mussels. This could provide valuable information on the impact of that specific factor on the mussels' survival.

Why do you need a control group and a experimental group?
A control group is not provided any treatment, while the experimental group is the one to which a treatment is applied. The control and experimental groups are chosen to be as similar as possible, so that the observed effect (if any) can be attributed to the variable: what only the experimental group consumes, uses, or participates in.
What could have been used as a control group in the fruit fly experiment?
In the fruit fly experiment, a control group could have consisted of fruit flies that were not exposed to any experimental treatment, keeping all other conditions the same. This control group would allow researchers to compare the effects of the experimental treatment with those of a baseline condition and help determine the true impact of the treatment on the fruit flies.
What is a blind trial?
A blind trial is a trial in which the subject does not know if he is part of the experimental group or the control group. In the case of a pharmaceutical trial, a blind study would be one in which the patients participating in the study would not know if they were being given the actual drug or a placebo. A double-blind trial is one in which neither the patients nor the doctors involved in the study know which patients are in the control group and which patients are in the experimental group.
What are the components needed in order for an experiment to be valid Identify these components in the following experiment A scientist is testing a new plant food to see if it causes plants to grow?
Peer review does the same thing for science that the "inspected by #7" sticker does for your t-shirt: provides assurance that someone who knows what they're doing has double-checked it. In science, peer review typically works something like this:
What is the science of observing and describing organisms in their environment paired with experimental science?
That would be ecology. Ecology is the branch of biology that studies how organisms interact with each other and their environment, including observational and experimental approaches to understand these relationships.
What is an experimental group?
An experimental group is the group that gets changed. For example if there was a disease and there were 2 different products to cure it, the group, let's say group A, with the product that works, would be the experimental group. This is because it is the group with the product that has been changed for the experiment. The other group, group B, would be the control group because it has the product that stays the same as if nothing ever changed, because that product doesn't work.
What is the difference between a control group and an experimental group?
Control groups do not test the variable or action. They are a constant comparative base. The experimental group has one different variable. They two are compared to see what affect (if any) the variable has. The control group is not exposed or subjected to what they're testing. The experimental group is. For example, a control group and an experimental group may each consume the same foods, on the same schedule. The experimental group would also receive a nutritional supplement, to see if it had any beneficial effect. This would ideally be the only major difference in the two groups.
What is an example of an experimental group?
An experimental group is a group of subjects in an experiment that receives the treatment or intervention being studied. For example, in a study looking at the effects of a new drug on blood pressure, the group that is given the drug would be considered the experimental group.
What is the group of participants chosen for an experiment called?
When conducting an experiment, there are two groups. One group is called the experimental group. This is the group that the treatment is being given too. The second group is called the control group. This group is not given the treatment and is used to compare the experimental group with. An example would be: A new medicine for heartburn was being tested. The experimental group would be given the medicine. The control group would be given a sugar pill. When the treatment was done, the results of both groups would be compared and a decision would be made as to the medications effectiveness.
What would most likely occur if an experimental design specifies only test group?
The experiment would lack a control group
What is a experimental group?
In a scientific experiment it is common to split your sample into (at least) two groups. Say you were to study the effect of a new drug on a specific condition, you would have a sample (a group of people with the condition in question e.g. breast cancer), and you would treat all members of the sample the same, with the exception that one group is give the actual drug, and the other group is given a "fake" pill. This fake pill is also called a placebo. The group that is given the real drug is called the experimental group, and the group that is give the placebo is called the control group. This setup attempts to ensure that any effect that is observed is caused by the drug (the experimental condition).
What kind of leaves mussels eat?
Mussels are shellfish, not rabbits. I would suggest not feeding mussels leaves.
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 correct a group of students was asked or a group of students were asked?
The correct phrasing would be "a group of students was asked." In this case, "group" is considered a singular noun, so the verb "was" should agree with it. This is because "group" is acting as a single entity in this sentence, even though it is made up of multiple individuals.
What does control means in a scientific method?
Usually, there are two groups, a control group and an experimental group. For example, if you were showing how plants grow with fertilizer versus manure, the control group would be the fertilizer or the manure, depending on which you usually use. The experimental group would be the new substance, because you are experimenting on that. The control is what you give to the control group, if I am not mistaken. It is what you are not changing.
What is the difference between control group and experiemental group?
The experimental group is the entire population of people in a testing program. The control group is a subset of that unit. The control group would be given a sugar pill instead of the drug being tested. This is done without even some of the experimenters knowing who is who.
