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 it mean if a scatter plot has no association?

Back

It means that there is no discernible pattern or relationship between the two variables being plotted.

Front

What is a positive association in a scatter plot?

Back

A positive association means that as one variable increases, the other variable also tends to increase.

Front

What is a negative association in a scatter plot?

Back

A negative association means that as one variable increases, the other variable tends to decrease.

Front

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

Back

The slope of a line indicates the direction and steepness of the relationship between the two variables.

Front

What does a slope of 0 indicate in a scatter plot?

Back

A slope of 0 indicates that there is no change in the dependent variable as the independent variable changes, meaning the line is horizontal.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that differs significantly from other observations, which can affect the overall trend of the data.

Front

How can you identify a positive slope in a scatter plot?

Back

A positive slope can be identified when the line rises from left to right.

Front

How can you identify a negative slope in a scatter plot?

Back

A negative slope can be identified when the line falls from left to right.

Front

What does it mean if a scatter plot shows a cluster of points?

Back

A cluster of points indicates that there is a strong relationship between the two variables in that region.
