What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

Front

What does a linear relationship in a scatterplot indicate?

Back

A linear relationship indicates that as one variable increases or decreases, the other variable tends to increase or decrease in a consistent manner.

Front

What does it mean for 'y' to be a function of 'x'?

Back

It means that for every value of 'x', there is exactly one corresponding value of 'y'.

Front

How can you identify a scatterplot that does NOT suggest a linear relationship?

Back

Look for patterns that are curved or scattered without a clear trend, indicating no consistent relationship.

Front

What is the purpose of making predictions based on a scatterplot?

Back

To estimate the value of one variable based on the known value of another variable using the observed relationship.

Front

What is the best prediction for the length in feet for a shark that is 9 years old based on a scatterplot?

Back

The best prediction is the value that corresponds to the 9-year mark on the scatterplot, which is 23 feet.

Front

What is the difference between a function and a non-function in terms of graph representation?

Back

A function will pass the vertical line test, meaning no vertical line intersects the graph at more than one point, while a non-function will fail this test.

Front

What does the term 'vertical line test' refer to?

Back

The vertical line test is a method to determine if a graph represents a function; if a vertical line crosses the graph more than once, it is not a function.

Front

What are independent and dependent variables in a scatterplot?

Back

The independent variable is plotted on the x-axis and is manipulated, while the dependent variable is plotted on the y-axis and is measured.

Front

How do you interpret the slope of a line in a scatterplot?

Back

The slope indicates the rate of change between the two variables; a positive slope means both variables increase together, while a negative slope means one increases as the other decreases.
