Question
Homework #5 EAB 705 A small study was carried out in which we selected 100 women with endometrial cancer and 100 women without apparent endometrial cancer. All 200 women were then contacted and asked whether they were obese at age 50 or not. They were also asked about other characteristics like race, and parity. 1. What kind of study design is this? Why? What is the association/relationship that is being studied? Consider that among those with endometrial cancer, 75 were obese at age 5o, and among those without endometrial cancer, 60 were obese at age 50. What is the appropriate measure of association called? 2. 3. 4.What is its magnitude? (quantity) s,/Articulate your findings in 14, assuming your estimate is statistically significant 6. Do you think there would be a problem with "Recall bias" in this study? Why or how? 7. How would that "Recall Blas" influence the "real" measure of association-Will the odds ratio (OR) found in this study be higher than the real OR, lower than the real OR, or the real OR? What is the incidence rate for endometrial cancer in the study population? In the epidemiological context, why do you think the researchers would want to collect information on race and parity? 8. 9.Explanation / Answer
1-observational study. An observational study attractions implications from an example to a populace where the self-governing mutable is not under the regulator of the investigator since of principled worries or logistical restraints.
2-relationship between obesity and endometrial cancer is studied in this passage.
3-Observational studies examine and record contacts such as interferences or hazard influences and detect results as they happen. Such studies might be virtuously expressive or more logical.
4-Here to measure the association amid two issues, that is, the result of an involvement or contact on a result. To quantify the result we will requirement to distinguish the degree of consequences in a contrast cluster as well as the interference or uncovered group.
5-Whether the investigator vigorously variations a influence or levies uses an interference controls whether the education is measured to be observational as inert participation of investigator, or trial vigorous participation of investigator.
