Two Forms Of Tos Table Of Specifi Ions

Mar 16, 2021

Jun 05, 2018 The table of specifications (TOS) is a tool used to ensure that a test or assessment measures the content and thinking skills that the test intends to [Page 1655] measure. Thus, when used appropriately, it can provide response content and construct (i.e., response process) validity evidence. A TOS may be used for large-scale test construction

    Two other common elements having useful isotope signatures are carbon, 13 C is 1.1% natural abundance, and sulfur, 33 S and 34 S are 0.76% and 4.22% natural abundance respectively. For example, the small m/z=99 amu peak in the spectrum of 4-methyl-3-pentene-2-one (above) is due to the presence of a single 13 C atom in the molecular ion. Although less important in this
