    So many factors
    in my life changing at once:
    I am confounded.

    A: A census found there’s a brazillion.

    Don’t try for a census 
    when the best thing’s a sample.
    But now how could a sample 
    surpass trying for all?
    Well, samples are faster 
    (so less outdated data)
    and samples are cheaper 
    (less workers to hire)!

    Sometimes a census 
    simply can’t even be done:
    If you needed a blood test, 
    should they take some or all?
    If they crash-tested all cars, 
    they’d have no cars to sell you!
    Just take a sample 
    from what is mixed well.

    If the sample’s much smaller 
    than the whole population,
    Then precision goals lean on 
    the sample size n,
    Not the sampling fraction: 
    that is really amazing!
    Don’t try for a census, 
    come sample instead!

  • Q: What do you call noting prices of the candy by the front door at your neighborhood 7-Eleven?

    A: Convenience sampling.
