    1 Great semi-quantitative representation
    2 if it was quantitative, vertical axis would-be logarithmic

    An approximated answer to @AgreeableLandscape@lemmy.ml question is (?) … in it’s footnote :

    infectious period varies with multiple factors, such has a person’s immune system and which variant they have.

      Well the axis isn’t labeled, so it could be log scale. It could also be any random range chosen by the graph maker. It looks linear though.

      Quantitative just means that it is represented in numbers. It doesn’t have anything to do with the scale used on a graph. Log scales do work better for analysis and deeper understanding of population data (like virus loads), but they are much less intuitive for most readers. These are absolutely quantitative data.

        virus multiplication is quite logarithmic … i could find supporting data, but i am sure you know this already.

          No need for supporting data. Virus populations definitely have exponential growth. I was just being pedantic about what quantitative means.

            So it could have been :
            semi-logarithmic graph
            “In science and engineering (…) a semi-logarithmic plot/graph has one axis on a logarithmic scale, the other on a linear scale.”

            But here :
            1 one axis has the scale : “low … high” (which is qualitative),
            2 the other has a linear scale (which is quantitative).
            so in this case and in this context :
            semi-quantitative seems fitting(?).

      … also theoretically one single virus copy (viral particle) could produce an infection, what i mean is that “infectious period” has gray zones.
