<p>If you really want to understand statistics you are going to need calculus first. Any statistics involving continuous data (real numbers) almost certainly at some level involves probability density functions, which are defined in terms of integrals. Doing very basic things like calculating the mean or variance of a continuous random variable involves integrals. If you take a statistics course that doesn’t require calculus, be prepared for a lot of hand waving and magic formulas. Really you’ll be learning applications of statistics not the theory of statistics itself. Whether that matters for law school or your career, I don’t know, but if you are actually interested in the subject it’s something to consider.</p>
