simple random sample- take a list (numbered) and randomly generate numbers from the frame to choose for your sample.

stratified random sample- divide your frame into strata and randomly sample from each stratum

systematic random sample- for example, take every 10th item from your frame

simple random sampling gives each subset in the frame equal probability

stratified sampling ensures that particular groups within a population are adequately represented in the sample and improves efficiency by gaining greater control on the composition of the sample

systematic sampling isn't that random... and only kinda efficient in databases...
