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 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 it mean if there is no correlation in a scatter plot?

Back

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

Front

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

Back

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

Front

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

Back

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

Front

What is the purpose of using a scatter plot?

Back

Front

What does the x-axis typically represent in a scatter plot?

Back

The x-axis typically represents the independent variable.

Front

What does the y-axis typically represent in a scatter plot?

Back

The y-axis typically represents the dependent variable.

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that differ significantly from other observations and can affect the correlation and overall interpretation of the data.
