Interpreting and making predictions with 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 the line of best fit represent in a scatter plot?

Back

The 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.

Front

What is correlation in statistics?

Back

Correlation measures the strength and direction of a linear relationship between two variables.

Front

What are the types of correlation?

Back

Positive correlation, negative correlation, and no correlation.

Front

What does a positive correlation indicate?

Back

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

Front

What does a negative correlation indicate?

Back

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

Front

What does no correlation mean?

Back

No correlation means there is no apparent relationship between the two variables.

Front

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 using the line of best fit to find the predicted value.

Front

What is the purpose of using a scatter plot?

Back

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

Front

What is an example of a negative correlation?

Back

An example of a negative correlation is the relationship between the number of hours studied and the number of errors made on a test.
