In this assignment, we will revisit the elemental concentration of glass evidence from Topic 3 in order to explore another analysis technique for further understanding the evidence. Refer to Table 2 in \"FOR-525 Elemental Concentration of Glass Evidence,\" located in Class Resources. This table shows that there are more elements to consider when comparing glass. Perform the appropriate multivariate analysis to compare the collected evidence to the control data. Table 1.
