Takehome points from correlation exercise: some subtle changes in genes can lead to drastically different correlation coefficients. For example, in scenario three, a gene that is close to evenly expressed across samples can have drastically different correlations if one point changes from 7 to 6. So, noise can be deceptive and lead us to believe that there are patterns where there aren't. Mathematical correlations don't always have biological significance.
