The exact value of that correlation is known as the correlation coefficient, which is calculated, using a special statistics formula that exists in your Excel list of functions. Note that statisticians like to distinguish between correlation and causation. In our example above, the fact that an increase in average temperature corresponds to an increase in average rainfall does not mean that one causes the other. It might just be that a third hidden factor causes both.
In this case, it is well known among meteorologists that an increase in humidity leads to an increase in both perceived temperature and rainfall.
That is why it is important to understand the distinction. Mapping correlations shows you where patterns exist; to say that it shows you what causes what would be to exceed its brief. You might not feel happy about having a scatter plot. Perhaps having a line through the data that shows how the relationship looks would be easier to understand. What you are looking for is the line of regression or the line that best fits the data you have before you.
This involves employing a regression formula that uses the correlation coefficient to find the best line of regression. The formulas above are for a single independent variable and a single dependent variable. However, as we have discussed above, sometimes there can be more than one independent variable in the equation. For example, we pointed out that simply plotting average temperature against average rainfall does not give the complete picture. Average humidity is yet another independent variable that influences both average temperature and average rainfall.tornado.burnsforce.com/poland-gua-de-bolsillo.php
