I am studying Statistics for business at introductory level, and having difficulty in handling the amount of information, partly because I am coming back to study after 5 years and I didn't do much stats at school.
I don't understand binomial distribution, inference and all the types of "errors" on my textbook. I did pretty well on the first 2 assignments, based on the Excel templates provided by the course and some common-sense thinking.
What are some key points that I should know about statistics? Would appreciate any help.
