Question

1. You hypothesize that crickets chirp more often when the air temperature is warmer. You collect male crickets. In the lab, you make four groups of crickets, with fifty crickets per group. Each group is exposed to a different temperature and you make sure that all other aspects of the environment are the same for each group. You record the chirp rate of each cricket and determine the average for each group. You repeat the experiment two more times in exactly the same way, but with new crickets each time. The data are: Average chirps per minute Temperature (°C) Groups of crickets Groups of crickets in experiment #1 in experiment #2 Groups of crickets in experiment #3 15 100 80 90 20 110 90 100 25 120 100 110 30 130 110 12 Sketch an appropriate graph of this data.
