Scatter Plots Unit 11 B

Scatter Plot A graph of plotted points that show the relationship between two sets of data

Bivariate Data A data that has two variables. (accuracy and speed)

Categorical Data A data that can be grouped by characteristics

Cluster Where most of the data is gathered

Outlier Data that lies “outside” of most of the data; data that is distinctly separate from other data

Correlation Relationship between two variables

Positive Correlation Relationship between two variables in which both variables react in the same way

Negative Correlation Relationship between two variables in which variables react in the opposite ways

No Correlation Relationship between two variables is non- existent

Linear Association Two variables have a relationship with a constant rate of change (slope)

Non-Linear Association Two variables do NOT have a relationship with a constant rate of change (slope)

Line of Best Fit A straight line that best represents the data on a scatter plot

Trend Line An extended line of best fit used to make predictions about future data
