The data for minimum sample size formulas are derived from extensive Monte Carlo simulations for n = 2 to 2000. Observed alpha values were determined empirically from the p-values of 100,000 replicate hypothesis tests for each n. Non-normal data with Skew = -5 to +5 and Kurt delta = -1...
the minimal number of experiments needed. We also provide a structural result for the minimum sample size, proving a conjecture on the optimal experimental design.doi:10.1080/03610926.2021.1938126Bernhard SpanglNorbert KaiblingerPeter RuckdeschelDieter RaschCommunication in Statistics- Theory and Methods...
ANOVA1_SIZE(f, k, 1−β, type, α, m, prec) minimum sample size required to obtain power of at least 1−β for a one-way ANOVA where k = # of groups, f = Cohen’s effect size if type = 1 (default), and f = RMSSE effect size if type = 2 NCP_ANOVA(R1, R2, v) ...
This test is an exact alpha-level test if the sample sizes are the same and conservative if the sample sizes are different (Hayter 1984). “With Best, Hsu?s MCB” tests whether means are less than the unknown maximum (or greater than the unknown minimum). This is the Hsu MCB test (...
Thus, I can say that I have unequal sample sizes for Mixed ANOVA. When I do the analysis by using SPSS, it calculates the sum of squares and degrees of freedom by using the minimum sample size of the first group, which is 490. Is there a way to make SPSS analyze all the data of...
where the alpha can be set at 0.05. it is also important to mention the sample size . you mentioned that you had three populations of cells. a minimum of 3 biological replicates should be used to conduct initial statistical comparisons to understand the effect size (signal) and variance (...
