TECHNIQUES - SamplingUsed in all fact finding exercises
Used in any type of fact finding Soil Water in a swimming pool
A small sample is taken to represent the whole

SamplingAdvantages
More control owing to smaller numbers.Less time
DisadvantagesHow is the sample chosen?Is it really representative?
