Question

A pharmaceutical company wanted to test a new drug developed to lessen the effects of

the common cold. To test this drug, scientists tested fifty volunteers, each of whom
was suffering the effects of a cold. Twenty-five of the people were given the drug.
while the other twenty-five were given a placebo, a sugar pill. None of the participants
knew who was taking which pill. All participants received a pill at 8:00 a.m. daily for the
first three days of the study. All participants lived in the same environment, with the
same climate, eating the same diet, and having the same level of activity. The severity
of the cold, hence the effectiveness of the pill, was determined by the number of
tissues each person used within a 24-hour period. At the end of a 7-day period it was
concluded that those with the sugar pill used the same amount of tissues as those who
had taken the new wonder drug. The executive committee decided to produce the drug
anyway thinking that the public would do anything to relieve the symptoms of a cold.

Answer 1

This question is incomplete; the remaining part of the question asks to

State the problem, the hypothesis, independent variable, dependent variable, control group, constants, conclusion and if the data is qualitative or quantitative

Please find the answer to each of the above mentioned below

Step-by-step explanation:

1. The problem of this experiment conducted by the pharmaceutical company is to test whether a newly developed drug will lessening common cold effects in people.

2. The hypothesis is testable explanation given to solve a problem. In this experiment, the hypothesis will be: IF the volunteers took the newly produced drug, THEN the severity of the cold will be reduced.

3. Independent variable is the variable that is manipulated or changed in an experiment. The independent variable in this experiment is DRUG because it is what is changed by the pharmaceutical company.

4. The dependent variable is the variable that is measured or tested in an experiment. It is what responds to change in the independent variable. In this experiment, the dependent variable is the EFFECT OF THE COMMON COLD/NUMBER OF TISSUES USED

5. The control group in an experiment is the group that is not administered the experimental treatment. In this case, the twenty-five people that were given a placebo, a sugar pill is the CONTROL GROUP.

6. Constants or Control variables are the variables that the experimenter keeps constant or unchanged throughout the experiment. In this case, the constants are the same environment, the same climate, eating the same diet, and the same level of activity.

7. The CONCLUSION of this experiment is that the sugar pill used the same amount of tissues as those who had taken the new wonder drug. This means that both the drug and sugar pill have the same level of effectiveness. Hence, the hypothesis is DISPROVED because the drug had no improved effect on the people.

8. A quantitative data is one which involves the use of values and numbers. In this experiment, the effectiveness of the pill was determined by the number of tissues used, hence, the data is QUANTITATIVE.
