Interpolate and Extrapolate Data

What is the approximate maximum heart rate of an 80 year old person?

• 40 beats per minute

• 45 beats per minute

• 50 beats per minute

• 80 beats per minute

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

Which of the following variables would be qualitative data?

• Gender

• Age

• Blood pressure

• Resting heart rate

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?

• extrapolation

• interpolation

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

• trend line

• interpolation

• extrapolation

• causation

A student used the graph below to determine that the maximum heart rate of a person should be 45 beats per minute when a person is 80 years old. Was this point determined by extrapolation or interpolation?

• extrapolation

• 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.

Predict how many push-ups should someone be able to do if that person runs 3.75 miles? Would this be considered interpolation or extrapolation?

• 29.29 push-ups, interpolation

• 29.29 push-ups, extrapolation

• .40 push-ups, interpolation

• .40 push-ups, extrapolation

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
