Scientists thought that modern man and Neanderthals were far less evolved, but in fact Neanderthals and modern man had much more in common and were more similar to what scientists originally thought.

This kind of "mistake" is normal because science is not completely correct, and everything is done through experimentation and hypotheses that lead to testing.

Your best friend frequently suffers from severe headaches. You have noticed that your friend consumes a great deal of diet cola,

timofeeve [1]

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.
