What is the difference between the independent variable and the dependent variable in experimental design?
The independent variable is the outcome you measure.
The dependent variable is what you can change.
The independent variable is what you can vary or manipulate.
The dependent variable is what you can vary or manipulate.
What are two possible ways that a team could come to a consensus in a disagreement over a solution to a problem?
Use a decision matrix and compromise.
Vote and let the majority decide.
Let the team leader decide.
Ignore the disagreement.
Why is it important for the team to come to a consensus on the issues that arise?
So the team leader can make all decisions.
So everyone is happy with the conclusion and participates.
So the team can avoid making any decisions.
So the team can work independently without guidance.
How can you design a product that meets the needs of a user?
