The concept CORRELATION not automatically means CAUSATION.
Step-by-step explanation:
Previous concepts
The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
And in order to calculate the correlation coefficient we can use this formula:
Solution to the problem
Some useful concepts are:
Correlation is a statistical measure described with a number that describes the size and direction of a relationship between two or more variables. The correlation between variables, NOT mean that the change in one variable is the cause of the change in the values of the other variable.
Causation is a term refered to one event as the result of the occurrence of the other event for example, there is a causal relationship between event A and B like a cause and effect. One important thing to mention here is that the causation is not an easy concept to measure.
"The difference between the two types of relationships are easy to identify since one can be measured with a numerical value and the other no (Here is one example: smoking causes an increase in the risk of developing lung cancer), or it can correlate with another ( smoking is correlated with alcoholism, but it does not cause alcoholism)".
So is clear that the concept CORRELATION not automatically means CAUSATION.
All you have to do is set up an equal proportion or
=
cross multiply to get 51x = 180*85 which is simplified to 51x = 15300 divide both sides by 51 to get x = 300 inches. Since the answer choices are in feet, divide 300/12 to get 25 feet
