# Bio Statistics in Health Care

TOPIC: Bio Statistics + Health Care
DESCRIPTION:
Please do not take if you do not know. RATIONALA for each question Total points=50 (20% of the course grade) 1. Which of the following research question we can use case-control study to answer? [ONE POINT] a. What is the past mortality or morbidity trends that can help estimates of the occurrence of disease in the future? b. What is the relative frequency of the characteristic or exposure under study when you compare histories and other information from a group of cases and from a comparison group? c. What is the possibility to analyze previous research in different places and under different circumstances to establish hypotheses based on cumulative knowledge of all known factors? d. What is the incidence of cancer in men who have quit smoking? e. None of the above
a. Past mortality or morbidity trends can help estimates of the occurrence of disease in the future because they can provide information about how common a disease has been over time. This can help to identify patterns and trends that may be useful in predicting future trends.

b. The relative frequency of a characteristic or exposure is the ratio of the number of cases with the characteristic or exposure to the total number of cases. When you compare this frequency between a group of cases and a comparison group, you can determine whether the characteristic or exposure is more common in one group than the other.

c. Analyzing previous research from different places and under different circumstances can help to establish hypotheses based on cumulative knowledge of all known factors. By considering a wide range of research, you can identify patterns and trends that may not be evident in any one study alone.

d. The incidence of cancer in men who have quit smoking can be determined by comparing the number of men who have quit smoking and subsequently developed cancer to the number of men who have never smoked or who continue to smoke. This can provide information about the potential protective effect of quitting smoking on cancer risk.
