[IHaveAnExamTodayFilter] I am a graduate student in social work. Today I have a midterm that will include questions on a few things I just cannot understand despite lectures, notes and a glossary. They include confidence level, confidence interval, standard deviation and margin or error. Can you explain this stuff to me, preferably in relation to one another? [more inside]
