Question

Bias is usually attempted to be controlled for in the design phase of many experiments. However, regardless of how strong a design may be, there is always the chance for random error, or error due completely to chance, to occur. Which of the following scenarios describes the most well designed experiment? For each of the others, briefly describe what could be done better. O None of these answers is correct. An investigator intends to weigh each sample for their study, and uses 10 different scales at once, one for each sample. While collecting measurements from a graduated cylinder, a team leader has each of the 10 measurements recorded by a diferent individual in the lab An Investigator needs to have an exact temperature for a specific reaction. Heishe uses the "gold standard" thermometer, and checks the temperature twice belore proceeding with the reaction.

Explanation / Answer

Option D is Correct

An Investigator needs to have an exact temperature for a specific reaction. Heshe used the gold standard thermometer and check the temperature twice before proceedig with the reaction
