Scatter Plot Association 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 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 significantly different from other points in the dataset, often lying far away from the trend of the data.

Front

How can you identify a cluster in a scatter plot?

Back

A cluster is identified by a group of data points that are close together, indicating a concentration of values in that area.

Front

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

Back

No association means that changes in one variable do not predict changes in the other variable; the points are scattered without a discernible pattern.

Front

What is the purpose of using scatter plots?

Back

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

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 it mean if a scatter plot shows a linear relationship?

Back

A linear relationship means that the data points can be approximated by a straight line, indicating a consistent rate of change between the variables.
