idk why but i excelled in stats in hs and college ! here’s some tips n tricks i liked
seconding the khan academy videos for help working through problems, crashcourse stats videos are great for breakdowns of different concepts and vocab. the desmos calculator (for computers) is cool. quizlet is great for remembering vocab and memorizing any formulas (if ur required to). if you have access to a free tutoring center on campus they can be really useful! talking through any concepts i wanted a better understanding of at first was so helpful
unfortunately a lot of it is just practice though. try calculating things one way and then calculate it another way to make sure you’re getting the correct results, you can look up problems online or if ur using a textbook see if there are extra practice questions in it. good luck!!
