Synthesis and organization, the two pillars of presentatin

Correlation coefficent are represented by r-values. R-values are from -1 to 1, where the further you are away to 0 and closer to -1 or 1 it shows a stronger relationship. In the image in the top left, the first two graphs are strongly correlated, while the third graph shows a weak relationship, as there are dots everywhere on the graph

Correlational study examples:

>Researchers go to a park and observe how many people visit on a hot day (Naturalistic)

>Giving out questionairres to people to determine SAT scores and socioeconomic status (Survey)

>Using a dataset to analyze the relationship between lung cancer and smoking cigarettes (Archival)
