Interpolation of Scatter Plot

Make predictions based on values inside the data points

• Interpolation

• Extrapolation

• Correlations Coefficient

• Residual

This means to predict a value inside the known values on a graph.

• trend line

• interpolation

• extrapolation

• causation

The scatter plot shows the relationship between the number of chapters and the total number of pages for several books.  Use the trend line to predict how many chapters would be in a book with 180 pages. 

• 12 chapters

• 15 chapters

• 18 chapters

• 21 chapters

Predicting the band grade after 3.5 hours of practice is an example of:

• Interpolation

• Extrapolation

• An outlier

What is the approximate volume of 300 g according to the graph above?

• 200 mL

• 250 mL

• 300 mL

• 350 mL

A student used the graph to determine that the volume of a sample should be 100 mL when the mass is 100 g. Was this point determined by extrapolation or interpolation?

• extrapolation

• interpolation

When using a regression line to predict a value inside the given range of explanatory values on a graph it is called....

• causation

A student used the graph to determine that the volume of a sample should be 300 mL when the mass is 300 g. Was this point determined by extrapolation or interpolation?

How many pushups someone can do can be correlated to the distance they run. The regression equation for this is pushups =0.72 + 7.62miles. Use this equation to determine how many miles should someone be able to run if that person does 24 push-ups? Is this considered interpolation or extrapolation?

• 3.06 miles, extrapolation

• 3.06 miles, interpolation

• 183.6 miles, interpolation

• 183.6 miles, extrapolation
