You can distinguish between correlation and causation and eliminate confounding variables by using random assignment. Experiments often create contrasts between a control group and one or more treatment groups as a crucial part of the scientific method.
<h3>When is random assignment appropriate in an experiment?</h3>
In general, whenever it is ethically feasible and appropriate for your research topic, random assignment should always be used in trials. Both random sampling and random assignment are crucial ideas in research, but it's critical to recognize their distinctions.
<h3>Is it moral to choose participants for an experiment at random?</h3>
Random assignment cannot be used to evaluate risky or unhealthy behaviour. For instance, it would be unethical to assign volunteers at random to one of the two groups and urge them to consume huge amounts of alcohol as part of an experiment on heavy drinkers versus social drinkers.

Answer: This is not plagiarism
Which of the following is true for the Student Version?
Word-for-Word plagiarism
Paraphrasing plagiarism
This is not plagiarism
Explanation:
Plagiarism is the use of a published work without attributing credit to the author. Word-for-word plagiarism is when a body of text is copied from the original work and made to seem like one's work.
Paraphrasing Plagiarism rewrites the text by substituting words with their synonyms but it still has the same information as the original text.
In this question, the student's version is different from the original text. The student argues for the efficiency of rapid prototyping while the original text explains why it is a possible design methodology for instructional design. What they both have in common is that they mention how successful rapid prototyping has been in software design.
Answer:
Check Explanation.
Explanation:
So, the question is about a research or an experiment on whether the intake of cola causes a lot of or severe headaches. And I will be using myself as the control experiment. Please note that I just did not want to use myself as the control experiment but because the question ask us to. That is the use of "single case design" which means that the person performing the experiment must use himself or herself as the control experiment instead of using another person.
Step one => I will make sure to know how often or how many times I do do get headaches.
Step two => I will then stop taking the cola, but after sometimes I will continue taking the cola back.
Using the single case design, I can test for my Hypothesis using the following steps;
For step two above, if during the period that I stopped taking cola, I did not have any headache and immediately I start taking the cola I started developing headaches, then
it is true that the artificial sweetener in the cola is responsible for the headaches.
To the second part of the question; I expect to find that that the artificial sweetener in the cola is responsible for the headaches.
My conclusion will be that the artificial sweetener in the cola is responsible for the headaches.
