A sample is a random picking of a number of elements of the population. If a population is made up of trinkets, then you pick some trinkets at random and measure something about them. The idea is that the mean and variance that you measure about the sampled elements is representative of the mean and variance of the whole population.
If you sample 50 trinkets, the population is all the trinkets.
