In one survey, fifteen randomly selected students were found to be taller than 6 feet. This data led to the conclusion that the average height of a student is greater than 6 feet. This is an example of __________. a. experimental error b. sampling error c. a subjective opinion d. experimental bias

What do you call a sample that goes through all the steps of an experiment but is not exposed to the experimental variable? control group dependent variable independent variable all variables/groups are exposed to the experimental variable

Theories change as new information becomes available. Which actions are most likely to lead to the discovery of new information? Check all that apply. 1.repeating experiments using the same experimental method each time 2.repeating experiments using the technology available at the time of the original experiment 3.repeating an experiment using the latest technology 4.developing a new experimental method to test an existing hypothesis

Design 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 etc

What is an argument for allowing assisted suicide or euthanasia for terminally ill patients? Describe an argument against allowing assisted suicide or euthanasia. Explain an example of medical researchers failing to respect the moral interests of research study participants. What went wrong? What principles could have been employed to better protect the participants?

Mrs. 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?

Some scientific reports are best described as correlations, in that they report on two events or conditions that tend to accompany one another. Correlations are often interpreted as evidence of a causal relationship between the two events or conditions. Other scientific reports involve experimental intervention and generally make a stronger case for a causal relationship. Pick one scientific conclusion that is put forth in this chapter that is based on both types of evidence. Which type of report do you find more convincing?

Create an experiment. Point out problem/questions, hypothesis, controlled variables, independent variables, and dependent variables

Please explain What are biological concepts of this experiment, limitations and improvements…Experimental techniques & the effect of the change of variables on the results
