To determine The brief description of how smoking could cause cancer when not all smokers get cancer. Explanation Given: There is a strong correlation between tobacco smoking and incidence of lung cancer, and most physicians believe that tobacco smoking causes lung cancer. However, not everyone who smokes gets lung cancer. Briefly describe how smoking could cause cancer when not all smokers get cancer. Explanation: If we suspect that a particular variable (the suspected cause), smoking is causing some effect, cancer then: 1. Researchers found correlations between smoking and lung cancer among many groups of people, women, men, and people of different races and cultures. 2. Among groups of people that seemed otherwise identical, lung cancer was found to be rarer in nonsmokers. 3. People who smoked more and for longer periods of time were found to have higher rates of lung cancer. 4. When researchers accounted for other potential causes of lung cancer (such as exposure to radon gas or asbestos), they found that almost all the remaining lung cancer cases occurred among smokers...

Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…
