For example the alpha level isn't calculated from the test statistic; it is simply designated. And the phrase "based on the comparison of the hypothesis with the significance level or on the p-value of the hypothesis" appears to be pure gobbledygook. Also, the "100 statistical tests" claim doesn't belong in the lede, and the source cited for it is not a reliable source for statistical theory anyway. Tag: references removed

  • 19:50 19:50, 3 February 2024 diff hist −329 HistogramAs noted in a previous edit explanation, there aren't an official "seven tools of quality." So it's silly to put that in the main info box for the article. Also the main image is full of "chart junk," i.e., pointless visual complexity (it is rainbow colored for no apparent reason). The other histogram images in the article are much better, simpler, and more representative of typical histograms.

  • 05:37 05:37, 29 January 2024 diff hist −274 HistogramThere's no particular reason a histogram can't be used to represent discrete (i.e., non-continuous) data. For example, you could have a histogram illustrating the number of pets that people own or the number of friends people have. Those aren't continuous variables because the values can only be whole numbers. The key distinction between histograms and bar graphs is that histograms typically represent quantitative variables. Quantitative variables aren't necessarily continuous. Tag: references removed

Ears have a limited range of frequencies they can respond to. Moreover, we don't directly "perceive" frequency. We perceive pitch, which is a subjective quality based on frequency. Also, a sonic boom doesn't mean the frequency is infinite; that would be outside the range of anyone's hearing and thus not a "boom." Tag: Reverted
