TA Name, Thursday Lab: 1:40 P.M. - 4:10 P.M.
Aim:
This experiment sought to gather data regarding water volume gathered in glassware,
then to statistically analyze the data, focusing on average and *standard*** deviation**, along with
relative error gleaned from linear regression.
Introduction:
This experiment was divided into two parts. For part one of the experiment, 25 mL were
transferred from a glass pipette to a tarred beaker and weighed using an analytical...

*Standard*** deviation**, in the other hand, is the measure of variation or the degree of dispersion of the data acquired around the sample mean. It shows the precision of the gathered measurements which implies that the measurements are less precise when a greater value is obtained. Otherwise, a lesser value should be calculated [3].
