Chi-square is calculated for two groups: DCSP ≥ 1 ≤ 5 and DCSP ≥ 6 ≤ 8 since categories 9 and 10 contained too little cases for valid testing.
Such a near-complete coverage of species in a clade is necessary for valid tests of speciational change hypotheses, as missing species introduce errors into estimations of the number of speciation events separating a given species pair [ 19].
Choosing the treatment protocol and dose range for fluoxetine and other serotonergic drugs is critical for obtaining valid test results and correct data interpretation.
The minimal criterion for a valid test of this hypothesis is a set of measures that can unambiguously establish that the stress came before the depression.
Positive control was with histamine base, 6 mg/ml (Stallergènes®, Antony, France) and had to be 3 mm or greater for a valid test.
Then, a 95% confidence interval for ψ0 consists of all values of ψ for which a valid test of the null hypothesis fails to reject at the 0.05 type 1 error level.
The Groningen Fitness test for Elderly is a reliable and valid test for the evaluation of physical fitness in the elderly (Intra Class Correlation coefficients (ICC) of individual tests varying from.83 to.96) [ 23].
In conclusion, the renewed JAAM scoring system for DIC appears to be a valid test for diagnosing DIC in patients with sepsis and may be helpful in specifically tailored management strategies in these patients [ 14].
But, of course, "coolness" is not really a valid test for literary worth (or anything else for that matter, except trousers).
