What does a line of best fit represent in a scatter plot?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, indicating the general direction of the relationship between the variables.

What does no correlation mean in a scatter plot?

Back

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

How can you estimate a value using a scatter plot?

Back

You can estimate a value by locating the corresponding point on the scatter plot and reading the value from the axis.

What is the purpose of using a scatter plot in statistics?

Back

The purpose of using a scatter plot is to visually display the relationship between two variables and to identify trends, patterns, or correlations.

How do you determine the strength of a correlation in a scatter plot?

Back

The strength of a correlation can be determined by how closely the data points cluster around the line of best fit; tighter clusters indicate stronger correlations.

What is an example of a positive relationship in a scatter plot?

Back

An example of a positive relationship is the correlation between hours studied and exam scores, where more study time generally leads to higher scores.
