- Which of the following is not correctly linked?a. model: a representation of an object used in an experimentb. standard deviation: a form of statistical analysisc. principle: a theory that is not supported by experimental evidenced. data: the results of an experiment or observationDesign 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 etcBackground: One of the most important steps that a scientist completes during an experiment is data processing and presentation. Data can be analyzed by the presentation of the data in table format (data table), or the processing of that data through graphical manipulation to visually discern the differences in the variables tested. Analyzing Data: The graph shows the number of shrimp hatched at different temperatures. 40 30 20 10 17 18 19 20 21 22 23 24 Temperature (Celsius) 1. What is the Independent (manipulated) variable? 2. What is the Dependent (responding) variable? 3. How would you summarize or caption this graph? In one sentence, connect the two variables. Number of Eggs
- 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.(1 question with multiple steps please answer) Identify the component characteristics of a scientific investigation Suggest alternative hypotheses that could be tested by the design Evaluate the validity of conclusions based on the given results Suggest ways to improve the experimental design Define and recognize examples of the experimental group, experimental variable, control group, control variable, independent variable, and dependent variable, and dataConsider the steps involved in an experiment that uses the scientific method. Arrange the six given steps in the order in which they occur. One of the steps will not be used. First step of investigation Final step of investigation Answer Bank Share the results and conclusions of the experiment. Choose the data that are most likely to support the hypothesis and ignore the rest of the data. Conduct the experiment and collect the resulting data. Make observations that raise a question about some aspect of a natural phenomenon. Analyze the data collected in the experiment. Form a hypothesis that can answer the question about the natural phenomenon. Design an experiment that tests the hypothesis.
- You are designing an experiment to test the following hypothesis: Temperature affects the ability of students to think clearly, and, therefore, students in a hotter room will have lower exam scores than students in a cooler room. 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?____________ 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 graphsThe general term for a systematic approach used in scientific study is quantitative analysis qualitative analysis O The scientific method The scientific controversy The type of data that involves measurements and numerical values is hypothetical data qualitative data quantitative data random data
- Come up with five ethical guidelines for research. Write statements that reflect your own views of what is right and wrong. If you really love animals, an example of one guideline might be "No animals may be used in research of any kind." However, when coming up with these guidelines, be thoughtful about what they really mean. Think of the information you read about earlier. Try to phrase your guidelines in a way that would allow research that you think would be beneficial to still be done. You may find that certain circumstances may cause you to rethink your own ethics!What are ethical concerns in using animals for research? Select all that apply: - many animals can be studied at one time - animals cannot consent to being used in experiments - some animals may have adverse reactions - animals are ideal biological modes for experimentsWhat measures an experiments ability for its results to be due to the treatment that was applied? intervening validily central limiting theorem internal vailidity
