In a controlled experiment, the experimental group is the set of subjects that receives the treatment or intervention being tested, while the control group does not receive the treatment and serves as a baseline for comparison. This allows researchers to observe the effects of the treatment by comparing outcomes between the two groups. The control group helps isolate the impact of the independent variable, ensuring that any observed changes in the experimental group can be attributed to the treatment rather than other factors.

What statement describes a controlled experiment?
fifteen turtles are fed iceberg lettuce and vitamins, while another fifteen turtles are fed only iceberg lettuce. :) APEX
What is a controlled experiment - apex?
A controlled experiment is a scientific investigation where one variable is systematically changed while all other variables are kept constant. This allows researchers to determine the effect of the manipulated variable on the outcome, ensuring that the results are reliable and valid. By comparing the results of the experimental group to a control group that does not receive the treatment, scientists can draw conclusions about causality. This method is essential for establishing clear relationships between cause and effect in scientific research.
What describes a reason for making a prediction when doing controlled experiment?
In scientific method the "prediction" is the theory that the scientific test (the experiment) is being conducted to prove (or disprove).
Which describes a reason for making a prediction when doing a controlled experiment?
To determine what sort of data table will be most useful APEX;)
In an experiment to see the effect sleep has on memory tests one group got eight hours of sleep a night and the other group got five hours a night. In this experiment what is the dependent variable?
The results of the memory test

Why are data tables used in controlled experiment?
To help organize data and record information... APEX :D
Why did mendels experiment use pure lines?
He needed a control group. *Apex*

What is the best explanation for hy a second control group was included in the experiment?
to help researchers conclude that results are related to the new drug and not to the orange juice <APEX> ^_^
What Only an experiment can prove apex learning?
An experiment can show: Cause and effect (Apex).

What describes the independent variable?
The variable is an experiment that is manipulated by the scientist. APEX
What describes an independent variableWhich of the following describes an independent variable?
for Apex: the variable is an experiment that is manipulated by the scientist.
Why did mendels use pure lines in his experiment?
He needed a control group. *Apex*
