Question

3 multiple choice 2 points
what is the definition of controlled variables?
the variable that is observed, measured, or affected by the independent variable
the variables that are kept constant throughout the experiment
the factors that can change or influence the outcome of an experiment
the variable manipulated or controlled by the experimenter
4 multiple choice 2 points
when you decide whether or not the data supports the original hypothesis, you are
forming conclusions
defining the problem
designing an experiment
forming a hypothesis
5 multiple choice 2 points
in a controlled experiment, controlled variables are variables that
change in response to the independent variable
change in response to changes in the dependent variable
are kept the same across all groups
are changed only within the control group

Explanation:

• Question 3: Controlled variables are variables that are kept constant throughout the experiment. This helps in isolating the effect of the independent variable on the dependent variable.
• Question 4: When you decide whether or not the data supports the original hypothesis, you are forming conclusions. This is the final step in the scientific method after analyzing the data.
• Question 5: In a controlled experiment, controlled variables are kept the same across all groups. This ensures that any changes in the dependent variable can be attributed to the independent variable.

Answer:

• Question 3: The variables that are kept constant throughout the experiment
• Question 4: Forming conclusions
• Question 5: are kept the same across all groups
