WebThe way I understand it, the answer choice would have to explicitly state "The percentage of data below/above the mean/standard deviation" as opposed to "The mean/standard deviation".In a standard normal distribution, the mean (µ) by itself is equal to 0, and the standard deviation (σ) is equal to 1. We know this because normal distributions are given … WebFurthermore, all these alternative methods rely on the distribution of the data rather than on the semantics of nominal values, which negatively affects the utility of the distorted outcomes. To tackle this issue, in this paper we present a semantically-grounded alternative to numerical noise suitable for nominal data, which we name semantic noise. corsair headset microphone driver https://sullivanbabin.com
