What is the difference between the sample mean and the population mean?
Madeline AlexanderAlso, population means are parameters while sample means are statistics.
A population's parameters are fixed, but typically unknowable, numerical values.
When we compute a statistic based on a random sample, we are said to have "observed a value" of the statistic. In essence, statistics are really (random) variables whose values change as different random samples are taken.
Sampling distributions in statistics provide a probabilistic explanation of how observed values change over numerous identically sized random samples drawn from the same population.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
