8.2.2. Brood development index (numerical example)
The
numerical example is a factorial experiment in which the factor product has two
levels (p): control level and test level. The factor repeated measures has five
levels (q): before exposure, three days after exposure, seven days, fourteen
days, and nineteen days after exposure. There are six hives (n) in each product
modality. In this design, each hive is observed under one modality of the
factor product. There are 6 independent hives in every treatment group. The
number of hives is twelve (2 x 6). The statistical model has npq = 60 data: n =
6, p = 2; q = 5. Example data are reported in Table 9.
Table 9. Example of BFD values for a numerical
example (see section 8.2.2.).
