Bivariate Analysis

Begins by analyzing two numeric variables by plotting them in a scatter plot.

Scatterplot

A graphical representation that shows the relationship between two numeric variables by plotting individual values as pairs.

Multivariate Analysis

When introducing another variable beyond just two variables.

Positive Association

Indicated when r > 0, meaning as one variable increases, the other variable also tends to increase.

Negative Association

Indicated when r < 0, meaning as one variable increases, the other variable tends to decrease.

No Association

Indicated when r = 0, signifying no correlation between the variables.

Strength of Association

Evaluated using |r|; if |r| is close to 1, there is a stronger association, and if it is close to 0, the association is weaker.
