Provide an example of a hypothesis using the method of concomitant variation (other than lung disease and cigarette smoking).
Concomitant variation is the frequency of a disease varies according to the potency of a factor.
ANS) Assume that a nurse observed 5 students.First student didn't eat the coleslaw( Salad dish of shredded raw cabbage ,carrot and other vegetables which is mixed with mayonnaise) and the student is totally all right,The second student ate a single piece of the coleslaw and experience a small nauseous,the third student ate almost 50 percentage of the coleslaw and is justly sick,the fourth student consumed a full plate of coleslaw and is strongly sick and lastly the last or fifth student had 2 plates of coleslaw and had run to the medical institution or hospital.The ending is that the coleslaw created indigestion.This is an example of a hypothesis using method of concomitant variation.
This proof displays that there is a straight connection between the degree to which the cause happened and the degree to which the consequences happened.This conforms to our usual belief that consequences are normally proportional to their starting points.This is a advanced edition of Joint method,one in which we observe not just the existence or non-existence of the informal terms,but the degree to which every one of them took place.So from this we can understand that the Concomitant Variation is the frequency of a disease varies according to the potency of a factor.
THANKS!!!!!!!

In 1856, John Stuart Mill presented three methods of hypothesis formulation in disease etiology: method of difference, method of agreement, and method of concomitant variation. Which of the following best describes the method of agreement? When the frequency of a health problem is different between two places, times, or circumstances, then there is evidence that the health problem is caused by a factor that differs between them When the frequency of a factor varies in direct proportion to the health...
Multiple Question: 12. The relative risk for dying from lung cancer among smokers is 10. The relative risk for dying from heart disease among smokers is 1.5. The etiologic fraction for lung cancer due to smoking is 0.8 and the etiologic fraction for heart disease due to smoking is 0.2. Based on these finding, we can say that Smoking seems much more likely to be causally related to heart disease than to lung cancer. Smoking seems much more likely to...
Lung Cancer & Smoking Case Study A causal relationship between cigarette smoking and lung cancer was first suspected in the 1920s on the basis of clinical observations. To test this apparent association, numerous epidemiologic studies were undertaken between 1930 and 1960. Two studies were conducted by Richard Doll and Austin Bradford Hill in Great Britain The first was a case-control study begun in 1947 comparing the smoking habits of lung cancer patients with the smoking habits of other patients. The...

The amount of money spent on food by undergraduate student-athletes and other undergraduates b. the average amount of time taken by white and brown rats to get out of a maze c. The effects of Drug A or Drug B on a disease d. The time to complete a task using Method 1 and Method 2
How would you rewrite this query using a method other than Union, the method that is currently being used. I need this same query rewritten, and if possible in a syntax that will work with Microsoft Access, as that is the platform that I have to test it. Here is the original query to be rewritten using a query other than Union: (SELECT EmployeeName FROM Employee_t E1, EmployeeSkills_t ES1, Skill_t S1 WHERE E1.EmployeeID = ES1.EmployeeID AND ES1.SkillID = S1.SkillID ...

Match the type of epidemiology/study with the example This type of study is the strongest at proving or disproving association and allows the researcher to control exposure to cases and controls. Examples of this type of a study include BRFSS, NHANES, PRAMS. This is (or these are) not a study but a form of epidemiology that includes analyzing rates, proportions, and ratios. This type of study is (or these types of studies are) most often used with testing a null...
2-2 CVS CAREMARK DISCONTINUES THE SALE OF TOBACCO PRODUCTS According to the American Cancer Society, smoking has resulted in $96 million in health care costs from 2000 to 2014. A well-established link exists between tobacco use and cancer. Public awareness of the dangers of smoking has led to shifting cultural norms, such that smoking is increasingly viewed as negative. Cigarette smoking in the United States has been on the decline since the 1950s. However, about one out of five Americans...
Regression and Correlation Methods: Correlation, ANOVA, and Least Squares This is another way of assessing the possible association between a normally distributed variable y and a categorical variable x. These techniques are special cases of linear regression methods. The purpose of the assignment is to demonstrate methods of regression and correlation analysis in which two different variables in the same sample are related. The following are three important statistics, or methodologies, for using correlation and regression: Pearson's correlation coefficient ANOVA...
