Content: What are some similarities and differences between descriptive research and experimental research design? Descriptive research answers scientific questions through observation, while experimental research design answers scientific questions by testing a hypothesis through the use of a series of carefully controlled steps. They are similar because they are both the two methods used to answer questions. What are the steps of the scientific method as we discussed them? recognize the problem, form a hypothesis, test your hypothesis, analyze your data, draw conclusions, and communicate your results
Why should bias be eliminated? because if you know the answer to a problem, then there is no point in doing the experiment. if you eliminate bias, you learn something. eliminating bias gives you an accurate result, and it is more reliable. What is the difference between an independent variable and a dependent variable? an independent variable is the factor that changes, and the dependent variable is the result or outcome being measured
Why are many constants needed?
