Scatter Plots

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 a scatter plot?

Back

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

Front

What are outliers in a scatter plot?

Back

Outliers are data points that fall far away from the other points in the scatter plot, indicating they do not fit the general pattern.

Front

How can you identify outliers in a scatter plot?

Back

Outliers can be identified visually as points that are significantly distant from the cluster of other data points.

Front

What does it mean if a scatter plot shows a negative relationship between time studying and questions missed?

Back

It means that generally, as the time spent studying increases, the number of questions missed decreases.

Front

What is the purpose of using scatter plots?

Back

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

Front

What is the significance of the slope in a scatter plot?

Back

The slope indicates the direction and strength of the relationship between the two variables; a steeper slope indicates a stronger relationship.

Front

What does it mean if a scatter plot has a slope of zero?

Back

A slope of zero indicates that there is no relationship between the two variables; changes in one variable do not affect the other.
