SUSB 003 Problem 2 2. The following results are obtained in five measurements of the density of an iron sphere. [ Should we view this as 5 independent determinations of density or as 5 determinations of mass and 5 independent determinations of volume? There are two possibilities: 1. The five determinations were made by 5 different investigators in which cases the headings 1-5 may represent the independent investigators who may differ in their competence, or the 5 determinations were made by the same investigator but under circumstances that differed from one determination to the next, making the weight and volume measurements dependent, or, 2. the results were carried out by the same investigator and the experimental determinations of mass and volume were independent experimental processes. ] Case 1 Let us consider the first possibility. Suppose each investigator carried out the weight and volume measurements and calculated a value from his/her data. What is the average density?
