Scatter Plots 8th Grade

Front

What is a scatter plot?

Back

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

Front

What does a positive association in a scatter plot indicate?

Back

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

Front

What does a negative association in a scatter plot indicate?

Back

A negative association indicates that as one variable increases, the other variable tends to decrease.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, showing the general direction of the data points.

Front

What does a nonlinear association mean in a scatter plot?

Back

A nonlinear association means that the relationship between the two variables cannot be accurately represented by a straight line.

Front

How can you identify a linear relationship in a scatter plot?

Back

A linear relationship can be identified if the data points form a pattern that can be approximated by a straight line.

Front

What does it mean if there is no correlation in a scatter plot?

Back

No correlation means that there is no apparent relationship between the two variables; the data points do not show any consistent pattern.

Front

What is the purpose of using scatter plots in data analysis?

Back

Scatter plots are used to visually assess the relationship between two variables, helping to identify trends, correlations, and outliers.

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that differ significantly from other observations; they can indicate variability in the data or errors in measurement.

Front

How do you interpret the slope of the line of best fit?

Back

The slope of the line of best fit indicates the rate of change between the two variables; a steeper slope means a stronger relationship.
