a média mais e menos um desvio padrão


Explanation:
As barras verticais definem uma faixa, que vai da média menos um desvio padrão até a média mais um desvio padrão. Ou seja, 68,27% dos valores, de acordo com a explicação no link. Assim que entendo a frase.

Example sentence(s):
  • In statistics, the 68–95–99.7 rule is a shorthand used to remember the percentage of values that lie within a band around the mean in a normal distribution with a width of two, four and six standard deviations

agree  Mario Freitas: Ok, but this "one" could be the value 1 instead of an article function, i.e., this could be "a standard deviation of plus or minus 1" not exactly well written in PT.

  -> Obrigado! Certainly "one" refers to one unit, i.e. "1". Note that the English says "plus AND minus", not "plus OR minus", and the "plus and minus" operate on the mean.
