Is not really necessary. A scientific control group is an integral part of scientific findings. A control group is a group separated from the rest of the experiment such that the independent variable being tested cannot influence the results.
The results from the control group provide baseline data that allow researchers to determine whether the application of a single independent variable has an effect. Plant A listens to classical music for three hours each day. Both a and b.

B It is used to randomly assign the participants into treatment and control groups. The control group in an experiment is the group that does not receive any treatment. This isolates the independent variable s effects on the experiment and can help rule out alternative explanations of the experimental results.
This group includes individuals who are very similar in many ways to the individuals who are receiving the treatment in terms of age gender race or other factors. Ensuring the reproducibility of the results A is best accomplished by keeping detailed records of the set-up and of the actual conditions of the experiment. An experimental group also known as a treatment group receives the treatment whose effect researchers wish to study whereas a control group does not.
In these designs you usually compare one groups outcomes before and after a treatment instead of comparing outcomes. B the experiment proceeds at a slow reactions and process all experimental data. However some experiments use a within-subjects design to test treatments without a control group.
This group plays as a starting point in scientific discoveries. They should be identical in all other ways. A control group allows you to compare those receiving the variable and those that are not.
Provides a point of reference against which the behavior of the experimental group can be compared. Plant B listens to rock music for three hours each day. A student conducts an experiment to see how music affects plant growth.

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.
A It is subjected to the condition that is being tested b B it is a sample taken through all experimental steps except the one being tested C It is treated identically as the experimental group D It tests the dependent variable 7 To test the effect of vitamin D on growth two groups of rats were. C There can be more than one difference between the control group and test groups but not several.

A controlled experiment is one in which A there are at least two groups one of which does not receive the pace to guarantee that the scientist can carefully observe all experimental treatment. Neither a nor b. The student obtains four identical plants.
This isolates the independent variables effects on the experiment and can help rule out alternative explanations of the experimental results. In an experiment an experimental group is a collection of subjects that receives the same treatment. Because it is not changed other variables may be.
This group control group consists of participantssubjects that do not receive the treatment allowing to make comparisons with other experimental groups. Which of the following describes an experimental group. Balances the experiment to eliminate all extraneous variables.
A The group in an experiment that only receives the variables being studied b The group in an experiment that receives all the conditions of an experiment except the variables being studied c The group in an experiment that receives all of the conditions of the experiment.
