What is a controlled expirement?

Answer 1

an experiment that can be controlled i did not know this

That is not a good answer!

A controlled experiment is:

If you set up an experiment:

Example:

You have two plants. You want to know if fertilizing every day causes it to grow more. In your experiment everything has to be the same! Except one thing. You have to have the same type of dirt and pot and flower/vegetable. You have to water each of them every day. But, you fertilize ONE of them once a day until your results are clear to you, or when you want to stop testing. This way, you can see how the fertilizer effects the plant growth compared to just water every day.

If you change more than one thing, like how much you water the plant, it is not a controlled experiment anymore. because then you won't know which variable (thing that you have changed) is taking effect. You wouldn't know if it was more water or the fertilizer, or both that is making the plant grow faster!

Answer 2

a controlled experiment is an experiment where the only changing variable is the manipulated variable. everything else is a constant. IE. in an experiment attempting to determine whether a rubber ball will bounce higher than a tennis ball, the height of the drop, the diameter of the balls, and the way of measuring the bounce will be the same. the only thing that is changed is the composition of the ball. that experiment would be a controlled experiment.

Answer 3

A controlled experiment is one in which there is strict control exercised on variables, with typically one or more variables being changed or "manipulated" while all other variables remain the same.

Answer 4

A controlled experiment is one where variables in the experiment are controlled throughout. Observational experiments, on the other hand, use less direct involvement.

Answer 5

A type of experimental design in which a hypothesis is tested under carefully controlled conditions, and the control group is compared with the experimental group.

Answer 6

There are many different kinds of controlled experiments. Most controlled experiments have many components that can be kept in check.

Answer 7

Where you control the variable factors that involve conducting the experiment.

Answer 8

A controlled expirment is an expirment with a control group and one or more expirmental groups.Only the variable differs from the control group.
