Sure. But if someone is using, for example, a notched boxplot to quickly evaluate differences in medians (i.e., they know how to correctly interpret a boxplot), it can still be a useful plot that conveys specific information that you would

Note that "not knowing how to correctly interpret a boxplot" is not equivalent to "boxplots are useless".

Makes sense to protest and raise hell before you get fired (or quit), in such a context, yes. What doesn't make much sense is to act surprised and complain that you got fired afterwards. Getting fired is exactly what one would expect w

Yup, for pea protein concentrates obtained by dry fractionation (arguably a slighly more complicated processing process than "just dried peas in a blender").

I'll just leave a final comment: if you restrict yourself to the arithmetic mean, then you can use Cantelli's inequality to make some claims about the distance between the expectation and the median of a random variable in a way t

Oh. I didn't understand that "roughly" was supposed to be doing all the work, in this context. I guess a 30/70 split is also "roughly" a 50/50 split, right? Example: > cat(paste0(data,collapse=",&q

Ok. So, let's try again... First, let's draw some data and show that the sample mean is not roughly close to the sample median: > data <- asinh(exp(rnorm(30))) > mean(data) [1] 1.227973 > median(data) [1] 1.059046 &g

Well... what do you mean by "a stable process" in this context? Let's try repeating the same example, but now drawing samples from a fixed distribution (in this case, a log-normal distribution): > data <- exp(rnorm(100)

...but then the algorithmic complexity goes from O(N) to O(N^2), or at least O(N log N), since points have to interact with each other. (N denotes the number of points you need to generate)

My favorite part is that there is no such thing as a "spectogram" (I assume they mean a "spectrogram"). The whole thing is hilariously bad :) love it.
