Problem
I. How is the standard error for a variable related to the standard deviation of that same variable? Think about the formula for the standard error.
II. Why can't we perform inferential statistics on non-probability samples, such as a snowball sample?
III. Why it is so important to researchers that sampling distributions have the shape of a bell shaped curve/normal distribution? Just try your best to think about why we do research and how the normal distribution can assist us in coming to conclusions.
