Quartiles are relevant for almost any distribution

• crazygringo 2y ago
  If by "almost any" you mean "unimodal". Quartiles are not relevant, i.e. can be highly misleading, for a bimodal distribution or beyond...

    they are misleading if you assume unimodality, but are always relevant. If you care about how many modes there are then likely you would prefer deciles or centiles. But even in the first image of the article the fact that two quartiles are close together means that there some density peak around there. I agree with the author that box plots are not good plots, but quartiles/deciles/medians are useful even for multimodal distributions
