Two determinations are needed for something to be spatially real: being in space and being extended in space.

Two determinations of the Nb5+ compound had global instability indices, G (eq 44), of 0.31 and 0.22 vu.
By plotting the difference between the pEC50 values determined by each of the methods against the mean of the two determinations it is possible to determine the agreement between both methods [ 10].
The different results reported in the paper are the average of minimum of two determinations.
These two determinations, however, lead to a contradiction involving external negation (See Routley 1980; Simons 1992, 185; Thrush 2001b).

For the irregularity indexes, random errors were calculated according to Dahlberg's formula (Se2 = Σd2/2n), where Se2 is the error variance and d is the difference between two determinations of the same variable [33].
The random errors were calculated according to Dahlberg's formula (Se2 = Σd2/2n) [27], where Se2 is the error variance and d is the difference between two determinations of the same variable and the systematic errors with dependent t tests, at P < 0.05 [28 30].
