Statistical Analysis Experiment for Freshman Chemistry Lab.
Salzsieder, John C.
Journal of Chemical Education, v72 n7 p623 Jul 1995
Describes a laboratory experiment dissolving zinc from galvanized nails in which data can be gathered very quickly for statistical analysis. The data have sufficient significant figures and the experiment yields a nice distribution of random errors. Freshman students can gain an appreciation of the relationships between random error, number of measurements, standard deviation, confidence interval, and null hypothesis. (PVD)
