Question

Your job is to check whether Vaccine A causes more people to have side effects than Vaccine B. Your sample consisted of 50 participants aged 20-35 years and mostly males. There is a written log of all the people who received both vaccines with the number of people who called to say they have had side effects.

1. What is the IV in the study?
2. What is the DV in this study?
3. What is the most appropriate statistical test you can conduct to fulfil your job

requirement. Provide justification to support your answer.

4,Are there any threats to the external validity of your study? Explain with reasons

5, What can you do to carry out double blinding in this experiment? What are the advantages of double blinding?

Answer 1

What is the IV in the study?

Vaccines A and B doses

What is the DV in this study?

The intensity and frequency of the side effects from the vaccines

What is the most appropriate statistical test you can conduct to fulfill your job requirement? Provide justification to support your answer.

The Chi-square test is an essential tool in associating detected and anticipated frequencies quantitatively. The Chi-square test can be incorporated to define the variance concerning the vaccinated groups in the magnitudes of the risk factor of the side effects of incorporating the same. 

Are there any threats to the external validity of your study? Explain with reasons.

The Experimenter effect may be a significant threat to the external validity of the study. Researchers may influence the partakers of the survey, or researchers may interpret the data to achieve the outcome they desire to acquire.

What can you do to carry out double-blinding in this experiment? What are the advantages of double-blinding?

Through incorporating a placebo-controlled study, one group can be given both vaccines, which entail the active treatment. In contrast, a subsequent group receives a form of treatment that has no substantial effect. Both the examiners and subjects of testing will be essentially unaware of the form of treatment deliberated to each group. Double blinding prevents bias in the results of conducted research.
