Those in a control group would not know they are in the control group, and they would not receive whatever manipulation that is being tested. If it is a drug being tested, those in the control group would receive a placebo (typically sugar pills or saline injections). If it is a behavior being tested such as exercise, the control group would either do a behavior like reading that has nothing to do with the experiment, or they would just mentally visualize that they are doing what is being tested (such as pretending to exercise). Now, if visualizing is the experiment, then maybe there should be two control groups, one that actually does what is being visualized, and one that does a more sedentary activity that has nothing to do with the experiment.
What else can I help you with?
In this experiment what is the control?
True
True or false. the control subject of an experiment be exposed to all variables?
False. The control subject (Or control group) should be kept isolated from the variables of the experiment. This group will detemine if changing a variable is better or worse than not changing the variable.
What is a sample that is treated exactly like all other experimental groups that the variable is not applied to it is a?
Again another of my homework questions and i think its control
Is it true or false a control group must be present in an experiment?
True!- Without a control group you have nothing to compare your experimental data with... so you cannot prove anything. An example: If you wish to test if a mutant plant grows better than a wildtype plant. You couldn't just grow the mutant plant and say it's better or worse than the wildtype if you haven't grown the wildtype plant aswell.
Randomization in an experiment means that the experimental units or subjects have been assigned to their respective test groups randomly?
True
True or false those who suffer from an eating disorder feel a need to control their body?
True.
In this experiment what is the control?
True
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.
Did Mendeleevs group his elements with those of similar properties?
Yes, this affirmation is true.
A placebo is a medication that elicits a positive emotional response in an experimental subject?
A placebo is used in an experiment as a control. For example, when testing a new medication, experimenters will split the group in two- a control group and an experimental group. The experimental group receives the actual medication, while the control group receives a placebo (in this case, a sugar pill). The placebo will not have any actual effect on the person, but is meant to make sure people aren't making themselves believe that they are cured.
What is the solution of the system means in math?
It means that values are assigned to each of the variables in such a way that, when replacing the variables for those values, EACH of the equations will be true.
True or false. the control subject of an experiment be exposed to all variables?
False. The control subject (Or control group) should be kept isolated from the variables of the experiment. This group will detemine if changing a variable is better or worse than not changing the variable.
Can a virtual phone number can be assigned to your cell phone to keep your true number private?
True!
What do control groups control?
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.
Why is a control group needed?
A control group is subjected to the same procedures as the experimental group but does not receive the treatment of the independent variable. In the control group all variables are held constant. It is used as a baseline measure. This helps determine whether any of the resulting effects of the experimental group are due to the independent variable treatment and not to the actions involved in providing the treatment.
Why is control important in an experiment?
Control is important in an experiment to eliminate the influence of variables other than the one being tested. By having a control group that is not exposed to the experimental treatment, researchers can accurately gauge the true effect of the independent variable on the outcome. This allows for valid and reliable conclusions to be drawn from the experiment.
What is a sample that is treated exactly like all other experimental groups that the variable is not applied to it is a?
