    I'm taking a distance course with a entry level stat paper and my ADHD brain just CANNOT concentrate on the 30 min recorded lectures. I just find my eyes drooping and my brain turning off with boredom, so THANK YOU, this pretty much covered one whole lecture and I kept up on 1.5x speed.

    All the sampling methods listed, except for convenience are random. A simple random sample is one form of random sample, and is arguably the ideal, as each observation is chosen completely independently of all the others.

    You should take a look at another video on the playlist from the UCMSCI channel called "Variation - why statistical tests are needed". Pretty much sampling helps us to find out information about a population when it isn't possible to collect information on the whole population.
