Compare and contrast random and systematic experimental errors with specific examples either real or fictitious. Explain how these types of errors can be identified and reduced in an experiment.
a) Does the data support your hypothesis?
b) How could you improve this experiment? Consider the other factors you could have / should have controlled in this experiment.
What is a null hypothesis in experiments? How is a null hypothesis used in science experiments?

How did you test your hypothesis? What independent and dependent variables were being investigated? What controls did you use? What were possible sources of error in your experiment?

- You observe that every time your neighbor, who always wears a yellow hat, walks out his front door, he gets dive bombed by a crow. From this observation, what is a testable hypothesis? What is your prediction based on your hypothesis? Please design an experiment to test this hypothesis and prediction. You must identify the independent and dependent variables, as well as at least 2 control variables, and your experiment must contain an experimental group and a control grouparrow_forwardYou are asked to draw and explain the goal of the Meselson-Stahl (1958) Experiment as outlined in the classroom. You need to draw your own diagram and use short sentences to explain the steps and/or important points, deductions. Clearly state what happens at each step.arrow_forwardDesign a (hypothetical) experiment that adheres to the Scientific Method. Be sure to include all the necessary requirements at each step and give examples at all of the steps. Start with an observation, whether it's real or made up, state the null hypothesis, and design an experiment (including an experimental and control group, random sampling, sample size, and reproducibility) that will allow the student to reject or fail to reject the hypothesis, and state (hypothetical) 'actual' results and the appropriate conclusion to draw from those results.arrow_forward

Give an example problem of pseudoreplication in a manipulative experiment and explain.arrow_forwardA business researcher is hired by a specialty retail firm. The retailer is trying to decide what level of lighting and what temperature they should maintain in its stores to maximize sales. Identify the independent variable and dependent variable in this case. How would the independent variable be manipulated to measure differences across the dependent variable.
