Homework Answers
Answer: C.Makes possible alternative explanations for the results.
Explanation:
While doing an experiment lot of variables influences dependent variable rather than independent variable.Those variables are called as confound variables. These confound variables enables possible alternative explanations for the results because these are influencing dependent variable.
For example: A Researcher wants to study a particular medicine decreases fever or not.
Part of experiment, researcher gave that medicine to patient who has fever. After consuming that medicine, patient took an injection. Here researcher can't say medicine reduced the fever. Because alternate explanation is injection also could reduce fever. Here injection is confound variable and made possible alternative explanation.

An experiment was conducted and the results involving the effect of a particular experimental variable was widely reported. Later a critic commented that, in fact, nothing could usefully be learned from the study because the observed effect was confounded. What did the critic mean by this? A) The experimenter really wasn't clear about what was desired so the experiment was not well defined. B) The results were so badly described that the critic could not figure out exactly what was...

4. Experimental design and hypothesis construction; graphing predictions Imagine that you were studying whether or not a particular genetic mutation increases the risk of developing psoriasis, a skin disorder, in dogs. You have access to 20 dogs that have this mutation, and 20 dogs that do not have this mutation. Write proper, formal null and alternate hypotheses for this experiment. Describe the experimental design you would use to test your hypothesis. You may use the 20 dogs mentioned above; beyond...
