In addition to the sources of error mentioned above, since the caliper jaws squeezed the flexible, rubber surface of the ball slightly, the measured diameters were slightly compared to what a non-contact method of measuring would provide. This represents an error in . This additional source of error significant. When the caliper jaws closed, the zero mark on the sliding Vernier scale, line up with the zero mark on the measuring scale. This means the caliper calibrated correctly.

MINORS,    SYSTEMATIC,   STATISTICAL,  BOTOM LINE, ZERO MATCHES

Explanation:

In general the sources of error or uncertainty can be classified

* Statistics. Which are those that describe the statistical formulas, for example: average, standard deviation, absolute error, etc.

* Systematic. That they occur due to an inappropriate measurement or to an interaction between the system and the instrument that cannot be quantified, in general this error shifts the measurements towards an explicit side

* Random, so errors that sometimes occur in the measurement and sometimes not, for example temperature changes during the medical process

In this case, you are asked to complete the sentences with the appropriate word

the measured diameters were slightly ___ MINORS compared to what a non-contact method of measuring would provide

. This represents an SYSTEMATIC error in .

This additional source of error STATISTICAL significant.

When the caliper jaws closed, the zero mark on the sliding Vernier scale, BOTOM LINE AND THE line up with the zero mark on the measuring scale.

This means the caliper ___ZERO MATCHES calibrated correctly.
