Question: The common pintail is 56 cm long. The fastest speed at which they have been known to fly is 23 meters per second.

The dragonfly has a maximum speed of 10 meters per second, and has a body length of about 9 cm.

The horsefly, with a body length of 1 cm, has a maximum speed of 7 meters per second.

A hummingbird can reach a maximum speed of 11 meters per second and have a body length of approximately 8 centimeters.

The willow warbler is about 11 centimeters long and has a maximum speed of 12 meters / second.

Which should be the independent variable and which should be the dependent variable. Why?

Fill in the first 2 columns, based on the above information. You can use the other columns for calculations.

Draw a scatter diagram. Label the axes.

Find the equation of the trendline. Draw it on the scatterplot.

Calculate r and r ² . How strong is the relationship? Is it positive, negative, or neither? What does this mean?

Answer one of the next two questions.

If body length is the independent variable: My dragon’s body is 30 cm long. How fast should I predict he can fly? Draw a star on that point on the graph.

If maximum speed is the independent variable: My dragon has a maximum speed of 8 meters per second. How long would you guess his body is? Draw a star at that point on the graph.
