Tidbits from Stats Calculator Online
Remember
Correlation is not causation
Pearson r measures linear association. Plot the scatter first, and prefer Spearman when the relationship is monotonic but not linear.

Read confidence intervals carefully
A 95% CI means that in repeated sampling, about 95% of such intervals would cover the true parameter—not that this one interval has a 95% chance.
