For what do scientists use the data from a controlled experiment?
Whenever possible, a hypothesis should be tested by an experiment in which only one variable is changed at a time. All other variables should be kept untouched and unchanged. Scientists use the data from a controlled experiment to explain the steps and outcomes that produced their final product.
What is an controlled experiment?
A controlled experiment can be used to test almost anything. In a controlled experiment, the scientist (or experimenter) use a control group and an experimental group. The control group has nothing changed about it, and experiment group is changed based on the variable of the experiment. One of the most common uses of controlled experiments is the testing of new medications. In a medical study, a pharmaceutical company usually brings in a group of 100 people. Those people people are randomly assigned to two groups of 50. The experiment group is given the medication being tested, and the control group is given a placebo (a sugar pill). After several weeks, the experimenter can then see the side-effects of the medication, by comparing the differences between the experiment and control groups.
What is the genotype of the control bulls he should use to test for the heterozygous genotype?
homzygous recessive
What is the purpose of having a control in an experiment?
I can best explain through example. Let's say that you are sea sick. You take two remedies, an acupressure bracelet and 50 milligrams of meclizine. You quickly start to feel better, but which of the two factors made the difference? The bracelet? The meclizine? A combination of both? This is a small-scale example, but in the fields of science it becomes important to know what causes a certain affect. This is the reason that we use controls.-Akilae
What is the use of a control group in an experiment?
A control group is must for every new experiment or uncommon experiment. Because when an experiment is being done anything unexpected could happen and to control the hazard a control group should be ready everytime. Otherwise it can be very dangerous for the experiment holders. to help you conclude that no uncontrolled factors significantly influenced your results
What is a control group in an experiment and why do we use them in experiments?
A control group is the normal condition of whatever it is we're experimenting on, and we use them to see if the experiment is doing what we want it to.
What described the step you use during an experiment?
the answer is procedure!!!!!!!!!!!!!!!! good luck if you are having trouble.
Why do scientists use a control in an experiment?
To find the variable in the experament
What is it called when you use the steps you ues during an experiment?
like have i al ready done this or like why is this happening and that's when you do an experiment
What is control group in science?
The one not experimented on. The control group is used to compare results to, to check that the changes you made during the experiment were responsible for the results seen in those groups. In other words, you use the control to confirm if the results shown in the experiment were caused by the independent variable (the variable that you change and are trying to investigate).
What do scientist use to collect data for an experiment?
Set up an experiment and a control group, which has an independent and a dependent group
What is the steps you use during an experiment called?
Procedure
Why do you use a control group?
You use a control group to compare the results of the experimental group to. The control group has the "normal" results. After the experiment, you can tell if and what has changed from the control groups results
What is a control in an experiment?
The control is what you keep the same through the whole experiment. I'm doing an experiment for a science fair this yer and its: What things can remove permanent marker from fabric. my control would be, the amount of "stuff" i use and the type or marker. hope it helps ♥
Can control in an experiment be changed?
no the control is that which is used to test your hypothesis. if mentos would blow up if you use caffeine and you used water, coke, and milk the water would be the control without it you cant do an experiment.
Why did mendels experiment use pure lines?
