Let's say you're testing a new drug to see if it helps with depression. We'll have 200 people split into two groups of 100 each. The first 100 people get the new pill, while the remaining 100 people get a placebo (sugar pill). Each participant does not know whether they are taking the actual drug or the sugar pill. This is important.

The control group is the group of people taking the sugar pill. This is to counterbalance the experimental group that takes the actual drug. If we just had one group, say the experimental group, then we wouldn't be able to compare those results against anything else.

Now let's say that everyone, in both groups, reported better moods and more positive attitude. This would strongly imply that the new drug is not effective because people who took the sugar pill got better. In other words, the sugar pill is as effective if not more so compared to the new drug. It may be the sugar pill, the psychology of taking any pill, or some other factors that contributed to those people getting better.

If only the people in the experimental group got better, then we could conclude that the drug is effective in some way. Again, we're making a comparison between the two groups, and the control group is used to reduce the placebo effect.

erastova [34]

Answer: Giselle has spent more than 1/2 of her parking money.

Explanation:

She has $40 dollars and parking lot cost $2.50 and she pays $2.50  for 9 days.

you need to multiply 2.50 * 9 and equals 22.5

now you need to subtract $40 - $22.5 and equals $17.5

now we need to know what is 1/2 of 40 and is 20 since $17.5 is less  than $20 Giselle has spent more than 1/2 of her parking money.

What insights about human nature, human psychology, and human society does the novel present? how are they expressed? lord of th
Kisachek [45]

Answer:

The central theme of the novel is the conflict between civilization and savagery, which also expresses the psychological confrontation between good and evil, as the social battle of law against anarchy. The good is represented in the instinct of civilization while the instinct of savagery represents evil.

Explanation:

The boys have to choose whether they follow rules and moral commands to guarantee a peaceful coexistence or they succumb to an instinctive search for power and gratification through violence. This is not only a personal dilemma but also shows how all the characters are influenced by an instinct of civilization as well as one of savagery to different degrees.

While Ralph represents civilization, Jack represents savagery.

Piggy and Roger are in opposite extremes as well, since the first doesn´t show any tendency to savagery, while the latter seems incapable of following the rules of civilization. Given that most boys succumb to savagery by the end, we can infer that Golding believes that the instinct of savagery is a primal element of the human mind while the instinct of civilization is forces on the individual by society.
