Spanish term

dosis letal media

Spanish to English Science Biology (-tech,-chem,micro-) Entomology
Para la determinación de la *dosis letal media* para el extracto crudo y el semipurificado sobre adultos de la mosca blanca se utilizó un diseño de bloques completos al azar con tres repeticiones por tratamiento.

I am not sure if I should use 'mean,' 'average,' 'median,' or 'medium' lethal dose. What is the difference? I found references with all of them :(

Thanks

average lethal dose

In this context, medium isn't correct.

Average = arithmetic mean, so mean is normally used only when you're talking about geometric mean or some other kind.

Median can be the midpoint, or the middle number in a seguence of numbers.

As Davidi indicates, "mean lethal dose" is more correct in this context.
Peer comment(s):

agree David Brown : but "mean" is the correct word in this case

Thanks, David; I stand corrected. Average is more correct mathematically, but mean more common in this context (althogh both widely used).
agree Dr. Roy Bheekha : Correct translation, I would say, even though it probably refers to LD50, which is de dose causing death in half the population.
