Events and Sample SpaceAn observation (measurement) is the result of an experiment. It refers to the process of gathering and/or measuring data. This can be done by a physical or chemical experiment, but it also includes data from surveys or economic data (e.g. stock prices). The only requirement is that the outcome is not certain, i.e. not known in advance. When we perform the experiment of throwing a die and recording the number
on the top face, we have six possible outcomes of this experiment. For
each experiment we can observe one and only one of these six basic outcomes
and the outcome cannot be predicted with certainty. The outcome cannot
be broken down into more basic outcomes. The collection (set) of all basic
outcomes is called sample space. Since observing the outcome of
an experiment is similar to selecting a sample from a population (in our
case the sample space), the basic outcomes are called sample points.
