Tables are a
convenient way of recording data. Nevertheless they
do follow certain conventions.

Degrees of
precision
-
Apply a simple rule. The degree of precision is equal
to the smallest graduation on the instrument.
-
You may need to estimate the degree of precision
sometimes especially with stop watches. Digital stop
watches are said to be accurate to 0.01s but your
reaction time is only 0.1s.
-
For electronic probes you may have to go to the
manufacturers specifications (on their web site or in
the instructions manual.
-
Some instruments have not degrees of precision
because their reading is relative.
Tables
can be arranged horizontally too, to save space
