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 does 'no association' mean in the context of a scatter plot?

Back

'No association' means that there is no discernible relationship between the two variables being plotted.

Front

What is a linear relationship in a scatter plot?

Back

A linear relationship is when the data points can be approximated by a straight line.

Front

What is a nonlinear relationship in a scatter plot?

Back

A nonlinear relationship is when the data points do not follow a straight line and may curve or cluster in a different pattern.

Front

How can you identify a positive linear association in a scatter plot?

Back

A positive linear association can be identified by a pattern where data points slope upwards from left to right.

Front

How can you identify a negative linear association in a scatter plot?

Back

A negative linear association can be identified by a pattern where data points slope downwards from left to right.

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 and to identify trends, patterns, or correlations.

Front

What does the term 'outlier' refer to in a scatter plot?

Back

An outlier is a data point that significantly differs from the other points in the scatter plot, potentially indicating an anomaly.
