Requirements of sampling

Why are we sampling?

Representative samples

how many samples do I need to reflect what is here?

Is the source homogenous?

Where and when should I take samples?

storage of samples

How will storage affect samples?

How do I need to store my samples if the storage is not to alter my results?

Taking the samples
