Huey and Dunham (1987) measured the running speed of fence lizards, Sceloporus merriami, in Big Bend National Park in Texas. Individual lizards were captured and placed in a 2.3-meter raceway, where their running speeds were measured. Lizards were then tagged and released. The researchers returned to the park the following year, captured many of the same lizards again, and measured their sprint speed in the same way as previously. The pair of measurements for 34 individual lizards is as follows:

a. With these data, calculate the repeatability of running speed.

b. What does repeatability measure?
