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.
The ratio of womenâs and menâs median annual earnings was 78.6 percent for full-time/year-round workers in 2014. This means the gender wage gap for full-time/year-round workers is 21.4 percent. Womenâs median annual earnings in 2014 were $39,621 compared with $50,383 for men.
