Some students investigated what size of quadrat they should use to assess the abundance of plant species in an old-field ecosystem. They used the quadrats os side 10, 25, 50, 75 and 100 cm and recorded how many plant species were present. They repeated their investigation five times and calculated mean numbers of species per quadrat. Their results are in the given graph.

Reasearchers investigated aspects of the anatomy of the Melina tree, Gmelina arborea which has been introduced into wet and dry forests in Costa Rica. The researchers wanted to know if the diameter of the trees at the head height was correlated with the overall height of the trees. The table shows the data for seven trees from each type of forest. The researchers calculated the Pearson’s correlation coefficient for the two areas as: The coefficient at p=0.05 for samples of this size is 0.75.
