Answer #1

This is a case of collider correlation, where two variables are highly correlated with third variable, i.e. asthma in this case. It is possible to have this kind of scenario where we found correlation of high rate.

yes, it explains a correlation and it is totally fine to find two variables correlated with third variable, even when the initial two variables are not correlated with each other. This is possible that two variables which are highly correlated with asthma(collider), are not correlated to each other.

Type of correlation depends upon what type of variables we are using, i.e. either continuous or categorical.

A Correlation Coefficient is a measurement of the relationship between two variables. A positive correlation means that as one variable increases, the second variable increases too. A negative correlation means that as one variable increases, the second variable decreases, or as one variable decreases, the second variable increases. Positive and negative correlations exists in nature, science, business, as well as a variety of other fields. Please watch the following video for a graphical explanation of the correlation coefficient: For Discussion...

1. Correlation: Correlation Does Not Mean Causation One of the major misconceptions about correlation is that a relationship between two variables means causation; that is, one variable causes changes in the other variable.

correlation measures the degree to which two variables are related to one another. Here are the definitions of the three possibilities: Positive correlations: In this type of correlation, both variables increase or decrease at the same time. A correlation coefficient close to +1.00 indicates a strong positive correlation. Negative correlations: This type of correlation indicates that as the amount of one variable increases, the other decreases (and vice versa). A correlation coefficient close to -1.00 indicates a strong negative correlation....
