A control group is a group in an experiment that is under normal conditions. If one was testing out fertilizer, the control group would be a plant with just normal dirt.

In an experiment, having more control groups than experimental groups is not a strict requirement; rather, it depends on the specific research question and design. Control groups serve as a baseline to compare the effects of the experimental conditions, so having multiple control groups can help account for variability and confounding factors. However, too many control groups may complicate the analysis and interpretation of results. The key is to balance the number of control and experimental groups to effectively address the research hypothesis while maintaining clarity in the findings.
Scientists use control groups to show how something will change under normal circumstances.

Not every experiment has control groups. If control groups are not feasible, you do what you can, and you may still learn something of interest. In the case of something like medical research, which really should have control groups, you can still use general statistical information to establish a baseline. People (for example) normally grow to a certain average height. We administer experimental drug X to our subjects, and they grow to a certain height which can be compared to the statistical average. This does tell us something.

it is the groups in experiment
Control groups are non-experimental groups -- that is, they have not been subjected to the experimental treatment. For example, if you are testing a new drug, the experimental group (also called the "treatment group") gets the drug, and the control group does not.Control groups are necessary in order to show that the treatment causes an effect. If the experimental group shows changes, but the control group does not, then it is possible that those changes were caused by the treatment. If there is no control group, then there is nothing to compare the experimental group to.Additionally, a control group is usually given an equivalent treatment. In the drug study, the control group would receive a placebo, such as a sugar pill. In such cases, control groups may be called placebo groups. This is done in order to show that any observed effects are caused by the treatment itself, and not by the process of administering treatment. In this way, we are controlling for the placebo effect -- a psychologically-induced response to a fake treatment, in which people begin to get well because they think they should be getting well.
In a free-market economy, private individuals or groups are in control
The Ottoman Empire emerged in what is now Turkey after which of these groups lost control of the area?
