Sigmas on normal curve
WebIt’s quite ironic really, sometimes, a normal distribution isn’t exactly the normal thing in the real world. Sure, with enough data we may end up leveraging the law of large numbers and tend to “normal” — but in some real-life scenarios (such as in finance), we may not have much data and the distribution is likely skewed. WebMay 19, 2016 · Hi all, firstly, thanks for the answers so far. The trouble is this: I simply can't add a normal curve... The data I'm working with are test results. Each candidate has answered several questions pertaining to scale_23 and thus has a collated raw average score that includes decimal points.
