Agreement levels
		Use Pearson’s R (-1 = perfect opposition, 1 = perfect agreement)
			Task									9 point scale								2 class (binary)
			1. Query (w/o results)											.577							.411
			2. Query (w/ results)											.604							.656
			3. Search Results											.745							.750
	Data analysis: • Relatively strong correlation (mostly above .6) • Stronger correlation with search results shown; easier task with more information • Most search results are not known items, high correlation for the final task
