I'm in final year high-school, (which is grade 13 where I live), and, as the title suggests, I'm seeking a book which introduces statistic/ probability with little prerequisites other than mastery of basic arithmetic and a good command and understanding of basic Algebra.
I will be self studying this, so ideally, the book should elucidate rather well written explanations for basic statistical notions.
I think Freedman, et al., is what you're looking for:
https://www.amazon.com/Statistics-Fourth-David-Freedman-ebook/dp/B00SLB5Q72
It's elementary, has good, intuitive explanations, and covers all the basic topics. I've taught out of this text several times, and I've never had any major problems with it.
