ACTIVITY 1. Given the following cases, solve for mean, standard deviation and variance. Express the measurement of the physical quantity completely.
1. In an experiment, 5 trials were done to determine the inside diameter of a ring. The measurements are as
follows: 1.24cm, 1.31cm, 1.28cm, 1.29cm,1.19cm mean, x= standard deviation, or
variance, oʻ=
Diameter of the ring =
2. During an experiment, a group of students was asked to measure the height of a liquid in a graduated
cylinder. The measurements were as follows: 5.3ml, 5.4ml, 5.6ml, 5.8ml, 5.1ml and 4.9ml.
