8th Grade Scatterplots

Front

What is a Linear Association?

Back

A Linear Association occurs when data points in a scatterplot lie close to a straight line, indicating a consistent relationship between the two variables.

Front

What type of relationship does a positive scatterplot show?

Back

A positive relationship indicates that as one variable increases, the other variable also increases.

Front

What does a negative linear association indicate?

Back

A negative linear association indicates that as one variable increases, the other variable decreases.

Front

What is a Nonlinear Association?

Back

A Nonlinear Association occurs when the relationship between the variables cannot be represented by a straight line, often showing a curve.

Front

What is an Outlier in a scatterplot?

Back

An Outlier is a data point that is significantly different from other data points, lying far away from the overall pattern.

Front

What does a Trend Line represent in a scatterplot?

Back

A Trend Line is a straight line that best represents the data points in a scatterplot, showing the general direction of the data.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x is zero.

Front

How can you identify a positive association in a scatterplot?

Back

A positive association can be identified when the data points slope upwards from left to right.

Front

How can you identify a negative association in a scatterplot?

Back

A negative association can be identified when the data points slope downwards from left to right.

Front

What does 'no association' mean in a scatterplot?

Back

No association means that there is no discernible pattern or relationship between the two variables represented in the scatterplot.
