A pressure measurement can further be described by the type of measurement being performed. There are three types of pressure measurements: absolute, gauge, and differential. Absolute pressure measurement is measured relative to a vacuum (Figure 2).
For example, the median tenure of workers ages 55 to 64 (10.1 years) was more than three times that of workers ages 25 to 34 years (2.8 years). Also, a larger proportion of older workers than younger workers had 10 years or more of tenure.
Maherâs researcher pointed to a 2012 Atlantic story that said the median age for these workers is more than 28, citing the BLS. (While Maher said average age and not median age, the median, or midpoint of a dataset, is actually a better representation of fast food workers as a whole, experts told us.)
