• Data with no variables

• Data with two variables

• Data with one variable

What does a scatter plot show?

• A histogram of data

• A pie chart of data

• A single data point

• a graph with points plotted to show a possible relationship between two sets of data

What is a cluster in a scatter plot?

• A curve fitting the data

• A single point far from others

• A collection of points that are close together

• A line connecting all points

What is an outlier?

• A point that is part of a cluster

• A point that does not fit the pattern

• A point that fits the pattern

• A point on the line of fit

What is positive correlation?

• There is no pattern

• As x decreases, y decreases

• As x increases, y increases

• As x increases, y decreases

What is negative correlation?

• As x increases, y increases

• There is no pattern

• As x increases, y decreases

• As x decreases, y increases

What does no correlation mean?

• As x increases, there is a clear pattern

• As x increases, there is no obvious pattern

• All points lie on a line

• All points form a cluster

What is a linear association?

• Data points lie in a curve

• Data points lie close to a line

• Data points form a cluster

• Data points are scattered randomly

What is a nonlinear association?

• Data points lie in the shape of a curve

• Data points form a perfect line

• Data points are scattered randomly

• Data points lie close to a line

What is a line of fit?

• A line that connects all data points

• A line that is very close to most of the data points

• A line that is far from all data points

• A line that forms a perfect circle
