What's the difference between a sampling frame and a population? Every internet explanation i seem to come across seems to make them seem more and more alike....
thanks in advance

Example: class with 30 people, the population is the whole class, the sampling frame is a list with each student's name, the sample is a selection (maybe 3, 5, 10...) of the 30

It's often the case in practice, especially where you're dealing with human beings as subjects, that certain members of the population are inaccessible for one reason or another. For example, if you're doing market research, there are those who love filling in surveys, but also those who abhor it! Can you guarantee that if you only sample from those who love it that you're getting a representative sample from the population with respect to the question under study? Nope!
So, if you really want to estimate population parameters, but you're limited to a sampling frame that is biased with respect to the underlying population, you explicitly acknowledge that this is the case by defining the sampling frame carefully, and you take statistical measures to attempt to deal with the problem.
