Basic Laboratory Statistics General Chemistry I and II Lab Manual Dakota State University page 226 of 232 Basic Laboratory Statistics In chemistry, we work very hard to control the environment to ensure that our results are well understood. We make sure that our equipment is clean to avoid extraneous reactions, we control temperature, heck, sometimes, we even control the amount of light in the room. It is not uncommon to find organic laboratories that happen to have windows to have aluminum foil over those windows to block any extraneous light, since this is typically an un-controllable and un-accounted for factor. Most importantly, we do many repetitions of the same experiment, to ensure that the results we get are not one-time flukes. To be a valuable piece of information, all experiments must be reproducible. As you get further ahead in your studies of chemistry, you will undoubtedly learn more about probability and statistics, but this is a good time to start with some basic concepts.
