You may have noticed how every algebra, geometry, trigonometry, or calculus course you take seems to require almost every concept you ever saw in your previously Math courses.
Statistics is NOT like that!
A good understanding of the five related algebra and geometry concepts of proportion, probability, percentage, ratio, and fraction will go a long way in helping you to understand statistics.
My statistics class.
My favorite college statistics textbook.
The three images below are the "answers" I wrote onto a blank Elementary Statistics test the day I returned the graded tests to students.
Whether in a class or tutoring session, I like to slowly write and explain answers as we proceed, often using a different color to distinguish each step and sending the student a PDF copy for easier review afterwards.
