Topic 5 DQ 1

PLease Respond to the following post with a paragraph, add citations and references.

The problem with this statement is that we are only presented with the “Given” which describes a linear correclation between number of cigarettes smoked and pulse rate. Linear correlation shows a relationship between the two variables – cigarettes and pulse rate- but never shows a causation. To show or prove a causation, a regression analysis needs to be performed.

Correlation is used to indicate relation, while a linear regression is a technique designed both to quantify a positive relationship between random variables, and prove that one variable is dependent on another variable

I affirm that a problem has been depicted since the linear correlation between the number of cigarettes smoked and the pulse rate does not show the relationship between the cause and effects of each other. Without conducting a regression analysis, determining causation between any two variables might be practically impossible (Hinton, 2014)…
