Figure 1 shows the beak depths of 200 medium ground finches on Daphne Major before a severe drought began on the island. This is a normal sample of a population of medium ground finches, similar to measured samples from previous years. During wet years, all types of seeds are abundant. The medium ground finch prefers to eat small, soft seeds that are easy to crush. However, during droughts, when small seeds are not as abundant, they also eat the larger seeds on the island.

a. Make two or three observations about the distribution of beak depth measurements in this sample of 200 medium ground finches.

b. What is the most common beak depth of the finches living on Daphne Major in 1976?

c. What is the range of beak depths in this group of medium ground finches?
