Synthesis, structure and cytotoxic activity of mixed-valent Cu(I)/Cu(II) salt containing a pyrazolone derivative as ligand

“…The data are presented as means ± standard error of the mean. Statistical differences between control and treated cells were assessed by unpaired t-test [44] and calculated by GraphPad Prism 4.0 software package.…”

‘Student’ and Small Sample Theory

“…In his 1908 paper on the correlation coefficient [12], Gosset mentions two typical questions. judging whether an observed r is consistent with an assumed p (in his case p = 0), but also (ii) he states that "we require the probability that p for the population from which the sample is drawn shall lie between any given limits."…”

“…In (12) we are assuming, in calculating the posterior distribution of p, that r is the only feature of the sample that need be considered whereas formally (10) implies that we consider all the sample values, although in virtue of (8) the quantities needed reduce immediately to (x, s. 8"" 8y and r). To investigate this further let us write f(B IIt "" Ity, U"" U lI, p) = fer Ip)f(S Ir, It"" ItY, U"', Uy, p)…”

Size and Power Properties of Some Test Statistics for Testing the Population Correlation Coefficient ρ

“…The distribution of r when ρ is zero was for the first time studied by a student [4]. Thus, a common test is that of whether or not a linear relationship exists between two variables X and Y.…”
