A controlled experiment involves a control group, which is a baseline group that does not receive the treatment or intervention being tested. This allows researchers to compare the effects of the treatment on the experimental group against the control group, helping to isolate the effect of the independent variable. By keeping other conditions constant, researchers can determine whether observed changes are due to the treatment itself.

What type of scientific investigation involves identifying and controlling variables?
laboratory experiment
Which type of investigation has a control group?
Medical type investigations require a control group; there are other types as well which may require a control group. The idea is to limit that number of variables. When you are trying out a new drug, you also have a group that has the same medical condition (arthritis, whatever it may be) but you give them a placebo, generally a sugar pill, instead of the drug that you are testing. That way, in case there is some effect merely from the fact that people are taking a pill, you can find out the extent to which the actual chemical composition of the pill is contributing to the outcome.
Why is a control needed in an experiment?
The control group gives you something to compare the results to. For example, in a medical trial for a new medicine, one group will receive sugar pills. Without this control group, it means nothing if 50% of those treated with the real medicine get better. The control group may have the same results, better results, or worse results. This tells how effective the medicine is. The same is done with any type of experiment.
What is the meaning of control in science form?
a control is when someone is performing a science experiment, the control group is a test group that is kept neutral and is used as a standard of comparison, for example if you are doing an experiment on whether or not music affects concentration and you have 6 test groups, each listening to a different type of music, you would want one group to not listen to any music at all to compare to the other results.
What experiment that tests only one factor at a time by using a comparison of a control group and an experimental group is and?
An experiment that tests only one factor at a time using a comparison of a control group and an experimental group is known as a controlled experiment. In this type of experiment, the control group remains unchanged and is used as a baseline for comparison, while the experimental group is subjected to the specific factor being tested. This design allows researchers to isolate the effects of the variable, ensuring that any observed changes in the experimental group can be attributed to that factor alone. This method enhances the validity and reliability of the experimental results.

What is in-depth investigation of an individual or small group?
An in-depth investigation of an individual or small group involves thorough research, analysis, and collection of information to uncover details about their background, activities, relationships, and behaviors. This type of investigation typically aims to reveal patterns, motives, and connections that can provide a comprehensive understanding of the subject(s) being studied.
What is the difference between a control group and a control?
A test group is the group in an experiment to which the change is being applied and the control group is the same type of group in an experiment to which nothing is done to compare the changes in the test group to.

What is the definition of descriptive investigation?
A descriptive investigation is a research method that aims to systematically observe and describe the characteristics of a phenomenon or a group without manipulating variables. It often involves collecting data through surveys, observations, or case studies to provide a detailed understanding of the subject matter. This type of investigation is particularly useful for generating hypotheses and identifying patterns or trends within the data.
What type of investigation would a scientist study this sinkhole?
The type of investigation would be fieldwork.
In a controlled group what group receives some type of treatment?
In a controlled group study, the group that receives some type of treatment is known as the treatment group. This group is compared with the control group, which does not receive the treatment, to determine the effects of the treatment.
During difficult economic times, people often want to blame a group for the condition of the economy. what is this type of blaming called?
It's called scapegoating I took the quiz in Apex. I thought it was categorizing.
What type of attorney is needed for a criminal investigation?
The title given to attorneys that are involved in criminal investigations is a criminal defense attorney or criminal defense lawyer. The criminal cases themselves are typically handled by the department of the attorney general.
In a controlled experiment what group recevies some type of treatment?
An experimental group is the group in an experiment that receives some type of treatment. The control group in an experiment receives no treatment. And, in conclusion, sometimes it might not work so be careful!!! :)
What are the key differences between acylation and alkylation in organic chemistry reactions?
In organic chemistry reactions, acylation involves adding an acyl group to a molecule, while alkylation involves adding an alkyl group. Acylation typically involves the transfer of an acyl group from one molecule to another, while alkylation involves the addition of an alkyl group to a molecule. Both reactions are important in synthesizing organic compounds, but they differ in the type of group being added to the molecule.
What is operating control?
a control type that involves over seeng the implementation of operating plans monitoring day_to_day results, and taking corrective action when required
