A well-designed experiment will contain both positive and negative controls. Which of the following is a false statement?
Choose one from the following:
(A) a positive control experiment is missing some of the components of the experiment and should give a negative result
(B) a positive control experiment contains all of the components of an experiment and should give a positive result
(C) a negative control experiment is missing the element being tested and should give a negative result
(D) if there are multiple components of an experiment, there should be multiple negative controls
(E) if a negative control experiment give positives results, it is likely that the experiment is contaminated
Which of the following is not mentioned by Marder (2011) as a category of experimental research?
A. Developing a mathematical model of a biology process
B. Measuring a value
C. Measuring a relationship between variables
D. Using computers for analysis
E. Improving and industrial product
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.
