By calcs do you mean calculus? I’ll assume so.</p>
<p>You can study or apply certain parts of statistics without calculus. But more advanced area require calculus. Have you ever heard of a continuous random variable? Have you ever head of a Poisson distribution? There is a link between probablility and statistics. A lot of statistics is meaningless iwthout knowing the probablity distribution you are using. This requires calculus. Without it the tables you look things up in are meaningless.</p>
<p>That doesn’t mean you need to know calculus to use basic hypothesis testing. But those formulas you use - z test, or t test, or chi square test or whatever. THey do come from somewhere. </p>
<p>I’m way too rusty to explain this stuff, but rest assured, in my engineering statistics class I needed to know calculus.</p>
<p>But let me give a basic example. Would you consider the mean, or average to be a statistical concept? I do. How exactly so you calculate the average value of a function without knowing calculus? How could somebody tell you the RMS value of a sine wave without knowing calculus?</p>
<p>Edit- I know I said I wasn’t going to post on this. But I had to say something about this.</p>
