What The one factor that differs between a control group and experimental group in a controlled experiment is the?
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.
What are 2 different ways to test a hypothesis?
Well since a hypothesis is "an educated guess that attempts to explain an observation or answer a question". It must be repeatedly tested with un-flawed experiments, and backed up with a significant amount of data. And it will then become a theory, and if it's tested by and consistent with generations of data it will become a law.
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 dose it mean if a scientists fails to reject a hypothesis?
It means there is no reason why he should reject it, whether because there is no evidence to the contrary or because an experiment set up to test it affirmed that hypothesis.
What were early scients not able to do to their theories?
Early scientists were not able to test their theories using advanced technology or conduct controlled experiments. They also lacked the mathematical and computational tools needed to fully analyze and validate their ideas. Additionally, they often lacked knowledge of underlying fundamental principles and had limited access to data and observations.
A controlled experiment allows the scientist to isolate and test?

When scientists cannot use a controlled experiment to test something what do they depend on?
Observation
What type of experiment is on way to test a hypothesis?
a. conclusion b.hypothesis c. data d. measurement
How can a scientist test a hypothesis if she or cannot do a controlled experiment?
scientists test their hypothesis buy making observations or doing research

What is a test of only one factor at a time?
A controlled experiment.
How do scientists test hypotheses?
Scientists test hypothesis by setting up an experiment. They choose a independent and a dependent variable and test the experiment.
What is a Test of hypothesis under controlled conditions is?
Testing a hypothesis under controlled condition is a scientific experiment.
A test set up under controlled conditions?
experiment
What test on factor at a time?

Activity done to test a hypothesis?
