Set B: Scatter Plot & Line of Best Fit Practice

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 is an outlier in a scatter plot?

Back

An outlier is a data point that differs significantly from other observations in a scatter plot, often appearing far away from the trend of the data.

Front

What does a positive linear relationship in a scatter plot indicate?

Back

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

Front

What does a negative linear relationship in a scatter plot indicate?

Back

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

Front

What is a nonlinear relationship in a scatter plot?

Back

A nonlinear relationship occurs when the data points do not form a straight line, indicating that the relationship between the variables is more complex.

Front

What is the slope-intercept form of a linear equation?

Back

Front

How do you identify the slope of a line from a scatter plot?

Back

The slope of a line can be identified by calculating the change in the y-values divided by the change in the x-values (rise over run) between two points on the line.

Front

What does it mean if a scatter plot shows no relationship?

Back

If a scatter plot shows no relationship, it means that changes in one variable do not affect the other variable, and the data points are scattered randomly.

Front

What is the purpose of a line of best fit in a scatter plot?

Back

The line of best fit is used to summarize the relationship between the variables by providing a linear approximation of the data points.

Front

How can you determine if a scatter plot has an outlier?

Back

An outlier can be determined by visually inspecting the scatter plot for points that are significantly distant from the overall pattern of the data.
