Question

what percentages of whean should we use in the treatments of our experiment?
a) 0, 25, 50, 75 and 100% with three replicates each
b) 0 and 100% with three replicates each
c) 0, 25, 50, 75 and 100% with one replicate each
d) 0 and 100% with one replicate each

Explanation:

In an experiment, using multiple levels of a treatment factor (0, 25, 50, 75, 100% of Whean) with replicates (three in this case) allows for a more comprehensive analysis of the effect of Whean percentage. Having replicates helps to account for variability. Options with only 0 and 100% or only one - replicate each are less informative.

Answer:

A. 0, 25, 50, 75 and 100% with three replicates each
