The calculated standard deviation is very low, thus,
indicating a
high
precision.
It also means that it has a
high
repeatability
as it
managed to produce nearly identical results across the five trials.
It also showed a very small percent error, which
means that the data is
quite
accurate.
The measurements drift only
slightly
over 5 minutes,
with an average difference of
0.001
grams, indicating the balance remains
stable
over short periods.
The
minimal
drift suggests that the balance maintains its
accuracy
over time.
This demonstrates that the analytical balance is
dependable
for
weighing
samples
without long
intervals between measurements.
