In the scientific method, one forms a hypothesis and then designs and carries out an experiment that tests that hypothesis. Most such experiments involve making and recording measurements that are quantitative (numerical) . Quantitative measurements may be discrete (countable or limited number of numeric values) or continuous (infinite number of numeric values). Uncertainty in measurements. Every physical measurement of a [continuous] variable is subject to a degree of uncertainty that, at best, can only be decreased to an acceptable level. The determination of the magnitude of this uncertainty is often difficult and requires additional effort, ingenuity, and good judgment on the part of the observer. Nevertheless, evaluation of the uncertainty in analytical data is a task that cannot be neglected because a measurement of totally unknown reliability is worthless. Unfortunately, there exist no simple and
