If a scatterplot shows dots forming a pattern that extends from the bottom left to the upper right, what kind of correlation does this represent?
Explanation
The visual pattern of a scatterplot provides an intuitive way to understand the direction of a correlation. An upward slope from left to right indicates a positive relationship, while a downward slope indicates a negative one.
