Of the quantities recorded in data tables 4 and 5 the base measures are the
measurements we physically measured such as finding the height of the cylinder by
looking for the main scale and vernier coincidence measurements and computing a mean
height in centimeters. Also, finding the mass of both the marble and the cylinder are
base measurements. The derived measurements are the volume and density calculated
for both the marble and the cylinder.
Which of the quantities recorded in Data Tables 4 and 5 are base measures
and which are derived measurements? Explain your answer.

Least count is the smallest number that is able to be measured on the vernier caliper.
Zero error is the number that tells us if their is and offset of the vernier caliper. If there is
an offset when closing the vernier calipers and looking at the placement of the main
scale zero and the vernier zero then the zero error needs to be calculated whether it is a
negative or positive zero error. Both the least count and zero error are computed before
any measurements were taken to avoid any measurement errors and to be aware of the
what the smallest measurement can be completed with the vernier calipers
