In the data table above, Cup #1 and #2 both had different values for average deviation from the average mass. Although they're the same type of cup, they both had different average masses. Based on this information I can infer that the third cup would have different values.

The other glassware become larger and in turn increase the uncertainty size. Lower uncertainty is more precise.

It's also more defined to read when looking at eye level compared to the top. If you were to view and measure from any other angle the data will be inaccurate.
