Based on the procedure described in the “Making Paper Money” section of “Making Money,” why is it likely that several engravers are involved in the process of making bills?

During the engraving process, as one engraver works on design elements, another must ensure anti-counterfeiting elements are added.

Each of the dies carved for the design of the bill require more than one engraver to complete the work because it is so detailed.

After one engraver carves an image, a second engraver must carve that image in reverse so that it prints correctly.

Each part of a bill’s design is carved on a separate die, and engravers specialize in crafting different parts of the design.

Reliability and validity reliability and validity are two important considerations that must be made with any type of data collection. reliability refers to the ability to consistently produce a given result. in the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways. unfortunately, being consistent in measurement does not necessarily mean that you have measured something correctly. to illustrate this concept, consider a kitchen scale that would be used to measure the weight of cereal that you eat in the morning. if the scale is not properly calibrated, it may consistently under- or overestimate the amount of cereal that’s being measured. while the scale is highly reliable in producing consistent results (e.g., the same amount of cereal poured onto the scale produces the same reading each time), those results are incorrect. this is where validity comes into play. validity refers to the extent to which a given instrument or tool accurately measures what it’s supposed to measure. while any valid measure is by necessity reliable, the reverse is not necessarily true. researchers strive to use instruments that are both highly reliable and valid.
