Scatter Plot & Association

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 grid.

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 an outlier in a scatter plot?

Back

An outlier is a data point that is far away from the main cluster of points in a scatter plot.

Front

How can you identify an outlier in a scatter plot?

Back

An outlier can be identified as a point that does not fit the general pattern of the other points.

Front

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

Back

No association means that there is no discernible pattern between the two variables; changes in one variable do not affect the other.

Front

What is the purpose of using a scatter plot?

Back

The purpose of using a scatter plot is to visually represent the relationship between two variables and to identify trends, patterns, or outliers.

Front

What is the x-axis in a scatter plot?

Back

The x-axis is the horizontal axis that typically represents the independent variable.

Front

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis that typically represents the dependent variable.

Front

What does a steep slope in a scatter plot indicate?

Back

A steep slope indicates a strong relationship between the two variables, either positive or negative.
