- Design 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_forwardList the three types of variables that are taken into account when designing an experiment, and briefly define each in your own wrods.arrow_forwardA controlled experiment ________. A. includes one group for which the scientist controls all variables B. is repeated many times to ensure that the results are accurate C. includes at least two groups, one of which does not receive the experimental treatment D. includes at least two groups, one differing from the other by two or more variablesarrow_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_forward____________ are often used to exemplify the relations that exist within a scientific experiment between the dependent and independent variables. Question 1 options: Ternary diagrams Rose diagrams None of the other answers are correct. Bar graphs Scatter plot graphs Line graphsarrow_forwardWhich of these factors is commonly manipulated during an experiment? independent variable dependent variable controlled variable continuous variable When carrying out an experiment, a scientist will observe changes in which factor? confounding variable dependent variable controlled variable independent variable Which of these factors remains intentionally unchanged in an experiment? controlled variable continuous variable independent variable dependent variablearrow_forward
- Which sentence best states the importance of using control groups ? 1-Control groups go through all the steps of experiment but lack the variable being tested. 2-Control groups eliminate the need for statistical tests.Control groups eliminate the need for statistical tests. 3-Control groups allow a smaller sample size to be used, so experiments are much cheaper.arrow_forwardExplain why we need to control variables that are not being tested in an experiment?arrow_forwardYou 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_forward
- 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 voidarrow_forwardChoose one of the three experiments performed by (1) Griffith, (2) Avery, McLeod, McCarty, (3) Chase, and Hershey. Explain the problem being solved, how the experiment was conducted, and how impactful the results have becomearrow_forwardIn the experiment described above, state what each of these parts of the experiment was: Independent variable Dependent variable Control group Experimental group One controlled variablearrow_forward
