Why is a controlled experiment important to science?

Answer 1

A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.

Answer 2

A controlled experiment is an experiment where you take into account multiple variables and there affects on the experiment in order to determine what exactly affects the experiment and how. This is important because it helps eliminate errors caused by assuming information. For example if you hypothesize balls bounce because they are round, you would have multiple round balls of different weights and sizes, to verify your hypothesis.

That is to say you are testing the aspect in question to verify your hypothesis.

Answer 3

A controlled experiment is important to science because an uncontrolled experiment may lead to many errors and mistakes that effect the whole process of doing an experiment or lab. It is easier to control certain variables than not controlling a specific or any variables in an experiment.

Answer 4

A control group is needed to set a base line for the experiment. Without a control group, there is nothing to base the experiment from.

Answer 5

If you do not have a control,then you cannot compare your test results.

Answer 6

Controls are important in an experiment because they are the way that the experiment is kept fair

Answer 7

A controlled experiment is useful because it is an experiment in which only one variable, the manipulated variable, is deliberately changed at a time.

Answer 8

The control is the object you compare the other trials to. It is important because, without something to compare to, you won't have correct data.

Answer 9

It is important to have controlled variables in a scientific experiment because it is the variable that remains the same it doesn't change. Its a consent & can be measured against.
