    This is more of a language question although it involves Biology statistics terminology.

    I was asked to review a short paper and I 've come accross this sentence. (Horrible English):

    The sample size was calculated considering the coefficient of variation of the biological effect of 15% for all experiments, except in the experiments of determination of protein content that was considered 20%.

    My question: Is the preposition "of" (highlighted) correctly used? Or could I express the same thing this way:

    The sample size was calculated considering a 15% coefficient ofvariation of the biological effect for all experiments except in those experiments to determine protein content, where a 20% coefficient was used.

    I'd apreciate any help!
    Hope everybody's having a nice Sunday...

    Hola. Para mí, "of" es correcto. Lo que sí cambiaría es "the coefficient of variation..." a "a coefficient of variation...". También diría: ", except in the (those) experiments for determining the protein content, where it was considered to be 20%".
    Saludos.

    Gracias, Ilialluna por tu ayuda.
    I did use "a coefficient" in my correction. Now the question of using "for determining" or "to determine" I'm always in doubt.
    Thanks again, your hints were very useful.
