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 grid.

Front

What does a positive correlation in a scatter plot indicate?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation in a scatter plot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What does no correlation mean in a scatter plot?

Back

No correlation means there is no predictable relationship between the two variables; the data points do not show any pattern.

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, indicating a consistent rate of change.

Front

What is a nonlinear relationship in a scatter plot?

Back

A nonlinear relationship is when the data points do not form a straight line, indicating that the rate of change varies.

Front

How can you identify a linear relationship in a scatter plot?

Back

You can identify a linear relationship by observing if the points cluster around a straight line.

Front

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

Back

It means that the data points do not show any predictable pattern or relationship.

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 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.
