Unlike normal line graphs (which usually show change over time), Scatter Plots show the relationship between two completely different things.

Imagine we ask 100 people two questions:

Positive Correlation (Going UP): "How tall are you?" vs. "What represents your shoe size?" (Taller people usually have bigger feet).
Negative Correlation (Going DOWN): "How fast do you drive?" vs. "Time to arrive?" (Faster driving means less time).
No Correlation (Random): "How much tea do you drink?" vs. "How smart are you?" (Probably no link at all!).

Type	Meaning	Visual Description
Positive Correlation	As X increases, Y increases.	Dots go up from left to right.
Negative Correlation	As X increases, Y decreases.	Dots go down from left to right.
No Correlation	No relationship between X and Y.	Dots are scattered randomly.
Strong vs. Weak	How close the points are to a line.	Strong: Dots form a tight line. Weak: Dots are spread out broadly.
Outlier / Anomaly	A data point that doesn't fit the pattern.	One dot stands far away from the others.
