Nice work there Vorlon.
I would argue that there is no such thing as a truly random sample though.
For those who don't know the definitions of the methods of sampling listed by The Vorlon, they are as follows:
Systematic Sample - A systematic sample is one that is random but where the choosing is based on some pre-described system.
e.g. Numbering each member of the population according to some criterion such as age/height and picking out every fifth one.
Stratified Sample - A stratified sample involves dividing the population into groups or strata. For each group you choose a random or systematic sample which reflects the proportion of that group within the population.
e.g. If the ratio of boys to girls is 2:1 in the population then the sample should reflect this.
I will be sure to burn all summer state polls that do not say Mason Dixon on them
.
