Question 5: The correlation and causation which are 2 births mingled with variable quantity stars are often confused in the scientific pursuit of prediction and explanation. In the general views, Correlation refers to a affinity between dickens (or more) variables in which they change together. For example, the kinship between ammunition and the hammer in a gun, when we offer the trigger, the hammer will hit the rim of ammunition.

We seam call the correlation relationship between hammer and the ammunition. A correlation can be positive/direct or negative/inverse. A positive correlation means that as mavin variable increases the other variable also increases. A negative correlation is just the opposite; as single variable increases, the other variable decreases. Causat ion refers to a relationship between two (or more) variables where one variable causes the other. For example, if you dont pull the trigger, you cant fire the bullet; or if the firing pin doesnt hit the rim, the bullet could non fire.

If we look back at the three criteria of causation above, you will notice that the relationship between hammer and the ammunition meets only one of the three criteria. The actually explanation of this relationship is the introduction of a third variable: trigger. Hammer and ammunition are changes during pull the trigger. Thus, turn these two variables are correlated,...If you want to get a full essay, order it on our website: OrderCustomPaper.com
