Together.
When X rises, Y tends to rise. This is a positive relationship.
01 / 06No straight story.
A cloud of points. No linear trend. But one number is never the whole picture.
02 / 06In opposite directions.
When X rises, Y tends to fall. Negative describes direction, not quality.
03 / 06A hint of a pattern.
A subtle tendency is still a tendency. Look at how loosely the points gather.
04 / 06Coming into focus.
As the points settle around a line, the linear association becomes stronger.
05 / 06A clearer connection.
A tight pattern. A stronger association. Context still determines what it means.
06 / 06One number.
A whole relationship.
Strong positive correlation.
A useful summary. Never a substitute for seeing your data.
Strength depends on context, sample size and the shape of the relationship.
Connected.
Not necessarily
cause and effect.
