Experimental work
Nice work Tuesday! As a reminder be sure to post the data collected to the wiki (be sure to make a graph of your data too). Also write a brief blog entry on to your personal page. In preparation for class Thursday, answer the following questions:
1. What is statistical error? 2. An old TV commercial used to say "4 of 5 dentists surveyed approve the use of Trident gum." If the manufacturer of this product only asked 5 dentists for their opinion, is this a valid survey? Why or why not?
