when examining every 1 mg/L and 2 mg/L of addition concentration. The importance for each hypothesis is set, and a closed testing order is a technique that allows
for sequential examination by importance. When an insignificant result is provided,
verification ends there. In the closed testing order, the entire examination and an
equal level of significance can be used for verification, or preset levels of importance
may be substituted beforehand. In other words, in the microcosm system, it is
thought that higher addition concentrations result in greater effects, so the addition
concentration is examined in descending order. Verification is terminated at the
concentration with no significant difference, and this is assumed to be the maximum
NOEC. The Way of thinking of the closed testing order is shown in Fig. 6.13.
