Experiment Design Analysis - Fossils in Cliff
Jose observed that different kinds and amounts of fossils were present in a cliff behind his house. He wondered what changes in fossils content occurred from the top to the bottom of the bank. He marked the bank at five positions: 5, 10, 15, 20 and 25 meters from the top. He removed one bucket of soil from each position and determined the kind and number of fossils in each sample.
