Abstract
From Chapter 4 we have inherited a table of data. Our objective is to analyze the relationship between the temperature and pressure data we collected and see if there are similarities between these measures; and if so, are they meaningful? How can we measure the correlation?

On the “Cloud,” which we will introduce in Chapter 6.

Imagine if we had only looked at the first 50 rows. At that point the two columns were highly correlated, but by the time we reached 100, the pattern had changed. Perhaps if we went to 150 rows the correlation score would change again? What about 175, or 200?

It is likely that you recorded a strong or moderately strong correlation. This is explained by Gay-Lussac’s law, also known as the pressure-temperature law: all other things being equal, if the temperature of a volume of air increases the, pressure increases, and vice versa.
