The null hypothesis is:
That the measured value is zero
That the proposed model is not correct and the measured factors have no effect on the pattern
That the proposed model is correct and perfectly explains the pattern
That the experiment is null and void
The 'control group' is an essential component of an experiment. This is because
1. A control group allows one to determine if a particular result is due to the experimental variable.
2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment.
3. A control group allows for multiple variables to be tested at the same time.
4. A control group is required for the development of a prediction.
What attribute should a hypothesis contain so that it lends itself to an objective experiment that relies on quantitative
observations and data?
Which is a properly written hypothesis?Which hypothesis states that no statistical significance exists between the independent
and dependent variable?
Question options:
statistical hypothesis
complex hypothesis
null hypothesis
alternative hypothesis
simple hypothesis

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_forward
- According to this experiment, summarize it and be sure to address the following questions: What hypothesis was being tested? 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? Please explain how the experiment you conducted supported or failed to support the original hypothesis.arrow_forwardDesign a SI modeled, detailed , yet hypothetical, biology experiment of your choice. In clear terms lay out all parameters of the experiment, including all controls and variables. Make sure that you clearly indicate where each step of the SI process applies(observation, question, hypothesis, analysis etcarrow_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

For your experiment, list the following Sample size Independent variable Dependent variable Control group Experimental group Standardized variables How will you ensure that you have a random sample?arrow_forward
- A 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. Include details about the experimental design including the experimental groups.arrow_forwardMrs. O’Grady wants to know if doing labs with her science class really helps them learn the material better. She decides to test this out in her two 6th grade science classes. In both classes she gives the same amount and type of notes and homework, but in one class she does labs and the other class she doesn’t. At the end of the unit, she gives both classes the same unit test and compares the class averages.what is the Independent variable: what is the Dependent variable:what is the Hypothesis:what is the Control group:what is the Experimental group:what is the Constants:what is the Possible threats to accuracy of results?arrow_forwardScientifically-testable statements that can be supported or falsified by experimentation are calledarrow_forward
