Question
Use the following scenario for the following four questions: In order to determine the effects of a new pill that is supposed to reduce hair loss, a researcher conducts a study. Five hundred volunteer subjects (300 men and 200 women) all of which suffer some degree of hair loss are selected to participate in the study. The researcher gives the women the real pill and the men a sugar pill, but only the researcher knows this. 14) Was this experiment blind, double-blind, or neither? Explain your choice. 15) Describe the control group in this study. 16) Describe the treatment group in this study. 17) The results of this study are likely to be invalid mostly because A) the subjects did not know if they were getting the real treatment. B) the gender of the patient could be a confounding variable in this study C) the subjects were volunteers D) the treatment group and control group were not the same size. E) none of theseExplanation / Answer
As per the current scenario, the answer will be as follows:
14. The current experiment is known as the Single Blind or Single Masked Experiment where by definition; the information that could bias or otherwise skew the result is withheld from the participant, but the experimenter will be in full possession or will have complete knowledge of the facts.
15. This type of control group is known as the Placebo Concurrent Control Group where the test drug is compared with an inactive preparation designed to resemble the test drug as far as possible or in simple language; the Experimental group is given the treatment and the control group is given the placebo (“Sugar Pill”).
16. By Definition, the experimental group is also known as the Treatment group and it the group that receives the treatment in an experiment.
17. The result of this study are likely to be invalid mostly because:
B) The gender of the patient could be a confounding variable in this study. Or
D) The treatment group and the Control group were not the same size.
