What is the independent variable in a scatter plot?

• The variable on the y-axis

• The variable on the x-axis

• The variable that changes based on the other

• The variable that remains constant

If your bank account balance is increasing, what type of correlation does it have?

• No correlation

• Negative correlation

• Undefined correlation

What does a negative correlation indicate?

What is a linear association in the context of scatter plots?

• A relationship where data points form a line

• A relationship where data points form a curve

• A relationship with no clear pattern

• A relationship where data points form a circle

How does a positive correlation appear in a scatter plot?

• Data points form a horizontal line

• Data points are scattered randomly

• Data points form a line going upwards

• Data points form a line going downwards

What type of slope is associated with a negative correlation?

• Positive slope

• Negative slope

• Zero slope

• Undefined slope

What does it mean if a scatter plot has no correlation?

• The data points form a clear curve
