I want to do ap stat but don’t have a strong base is algebra 2 at all
Yes, you should have a good algebra background before taking AP Stats.
Yes, do not take AP Stats without having earned at least a solid B in Algebra 2…
When do you use algII in statistics? Legitimately curious, the most advanced algebra concept is probably some applications of the binomial theorem?
Actually tbh, I don’t remember which advanced algebra topics show up. You should be familiar with manipulating expressions, summation notation, the binomial theorem and nCk operation. My AP stats class introduced logarithmic and exponential regression, as well as some basic facts about the normal distribution that likely weren’t on the AP test.
Of course, if you take an actual statistics class in college…
^ What @MITer94 said are actually not on the test. The Summation Notation used in Statistics formulas are really dumbed down. Exponential and Logarithmic Regressions practically never show up on the exam; in fact, I don’t even think that it’s required through the syllabus. Binomial Theorem and nCk are operations on the graphing calculator used, so it really isn’t useful to memorize other than understand what they are used for and how they are applied.
Manipulating Expressions is, however, important for AP Statsitics. There are so many variables that you need to solve for individually depending on what they ask. For example, let’s used the formula for Confidence Interval: x(bar)±z(sd/sqrt(n)). If they ask you for z, you need to know the other variables. The same applies to sd and n. You need to manipulate expressions in order to solve certain components. Other that, it’s mostly just plugging stuff in the calculator and understanding how they apply in the given question. This year’s free response was really weird since almost all of the questions were based on inference of given data rather than calculating stuff. (We didn’t get to construct a single confidence interval; There was only 1 Hypothesis testing; Barely any probability stuff.) Hopefully you won’t get that unlucky next year.
As with any math, a strong background in problem-solving will help. I recommend having a strong foundation in at least algebra first.
