After visiting a nature center, students were asked to contrast their observations based on location. Which of these students followed those directions?

Mr. Potter’s physical science classes conducted an experiment to determine the density of aluminum. Here are the density values each class period came up with: 1st hour = 3.1 g/ml, 2nd hour = 3.05 g/ml, 3rd hour = 1.9 g/ml, 4th hour = 2.35 g/ml, 5th hour = 4.2 g/ml, and 6th hour = 4.0 g/ml. If Aluminum’s true density is 2.7 g/ml, how would you group the class values based on accuracy?
