El hecho de que Gexp < Gtablas (0,44 < 0,68) indica que las varianzas de las concentraciones son homogéneas, es decir, que el factor concentración no influye en la variabilidad de los resultados.
Por otra parte, la ecuación de la recta obtenida tiene una correlación lineal R2 de 0,9996, valor aceptable (mayor o igual a 0,995).

As far as I can make out, it's the same in English. I'll carry on checking

Los resultados del análisis de la linealidad se muestran en las Tablas 2 a 4. Mediante un análisis de varianza (ANOVA), la homocedasticidad se demuestra aplicando la prueba G del test de Cochran, donde Gexp (SD=0,44; SMR=0,45 y SMT=0,15) es menor al Gtab ( =0,05, K=5, n=3)=0,68, lo que significa que las variancias para los diferentes niveles de concentración son homogéneas, mostrando así que el nivel de concentración no influye en la variabilidad de los resultados para los rangos de concentración definidos, por lo tanto no se presenta una relación estadísticamente significativa entre la variable explicativa (concentración) y el error experimental.

The only problem is that most of the English references I've seen are texts written by people with Spanish names. Gexp could mean 'grupo experimental', in which case I'm not sure what the translation would be.
Gexp appears a lot in texts about 'la prueba G de Cochran', though I can't find a G test, only Cochran's C and Q tests.

G statistic / observed value of G
The ST is a little confusing. What is happening is that the authors calculate the value of a G statistic (see e.g. link below) which is some variant of Cochran's test for homoscedasticity (that would have been a value of C).
This is compared to a table value, so G_exp is the "experimental" (more commonly known as the "observed" value). And it's not what is usually known as the "expected" value.

| Thank you, it is indeed about Cochran's test. In the following pages this test is named. |

: I was getting there, slowly, but I admit that the question has nothing to do with the subjects I work with.//But you've provided an explanation, something I can't do ;-)

Thanks Helena - it's something I've lived with for many years. And I think your answer works.
