6. Explain the process and purposes for an institutional review. Include an example of a study and the institutional review it might require.
The purpose of the Institutional Review Board (IRB) is to ensure that the rights and welfare of research participants are protected adequately. To accomplish this purpose, the IRB uses a group process to review research protocols and …show more content…
Give an example of scientific misconduct and describe the impact it might have on the generation of knowledge. Write a summary of your case in a few paragraphs.
An example of scientific misconduct includes the falsification of data. For instance, a researcher may report only "positive" results of a particular drug, omitting the non-findings or the number of serious side effects. Thus, the drug may have proven to be more harmful than helpful in a particular population. As an example, I can give the falsified research on the use of Celebrex and Vioxx in postoperative pain management. Both of these drugs caused an almost two fold increase in heart attacks and strokes before they were retracted from the market.
The main purpose of research is to know the truth and to benefit the subject and the society In addition, research aims to generate knowledge and differentiate between good and bad. Scientific misconduct provides a week scientific foundation for clinical work, creates inconsistencies, inefficiencies, endangers the medical practice, and creates endless idiosyncrasies (Neema, …show more content…
9. Differentiate probability from nonprobability sampling.
A probability sampling is a method of sampling that utilizes some form of random selection. Thus, every single member of a population has an equal opportunity to be in the study. Common types of probability sampling are: simple random, stratified random, cluster, and systematic sampling.
Simple random sample is a method of sampling in which the researcher uses a random table, number, or computer program to select from a population of interest who will be in the study.
Stratified random sample- involves dividing the population of interest into two or more groups based on certain characteristics that are important to the study and then randomly selecting members within each group. Cluster sampling- selects groups of subjects that are a part of a larger element that relates to the population and then selects smaller groups until eventually individual subjects are selected. Systematic sampling-involves selecting participants at a fixed interval from a list (i.e. every 2nd
