Creating a scatter plot graph relationship bivariate data

Creating a scatter plot

Interpreting a scatter plot Positive Association Negative Association No Association As x increases, y increases. As x increases, y decreases. No relationship between x and y.

Interpreting a scatter plot point line different Two clusters The outlier is (35, 28)

Predictions and trend lines straight above below outliers

Predictions and trend lines Approximately $1000

Write an equation

Tell me the definition of an outlier IN YOUR OWN WORDS. What does it mean to have
