What is a scatterplot?

Back

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

Front

What does a weak association in a scatterplot indicate?

Back

A weak association indicates that there is little to no correlation between the two variables being plotted.

Front

What type of association is shown when one variable increases and the other decreases?

Back

This is called a negative association.

Front

What is the definition of a function in mathematics?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

How do you determine if y is a function of x from a set of values?

Back

Check if each x-value corresponds to only one y-value. If any x-value has multiple y-values, then y is not a function of x.

What is the formula for the Pythagorean theorem?

Back

Front

What happens to the coordinates of a point when it is reflected across the y-axis?

Back

The x-coordinate of the point changes sign, while the y-coordinate remains the same. For example, point (x, y) becomes (-x, y).

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What is the relationship between the lengths of the sides of a right triangle?

Front

What does it mean for a scatterplot to have a positive association?

Back

A positive association means that as one variable increases, the other variable also tends to increase.
