What is a scatterplot?

Back

A scatterplot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional plane.

Front

What does 'nonlinear' mean in the context of a scatterplot?

Back

Nonlinear refers to a relationship between variables that does not follow a straight line; the data points may curve or cluster in a way that indicates a more complex relationship.

Front

What is slope in mathematics?

Back

Slope is a measure of the steepness or incline of a line, calculated as the change in the vertical direction (rise) divided by the change in the horizontal direction (run).

Front

What does a positive slope indicate?

Back

A positive slope indicates that as one variable increases, the other variable also increases, showing a direct relationship.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as one variable increases, the other variable decreases, showing an inverse relationship.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero, indicating no change in the vertical direction as the horizontal direction changes.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined because the change in the horizontal direction (run) is zero, leading to division by zero.

Front

What is correlation in statistics?

Back

Correlation is a statistical measure that describes the extent to which two variables are related to each other.

Front

What does a positive correlation mean?

Back

A positive correlation means that as one variable increases, the other variable tends to increase as well.

Front

What does a negative correlation mean?

Back

A negative correlation means that as one variable increases, the other variable tends to decrease.
