Software Listing: T Test

As you know, the Student t-test can be used only to compare two groups. When you have k groups you can't use a t-test for each couple because, if you have fixed alpha=0.05 for each t-test, there is a probability of k*0.05 to find a difference when it isn't (Bonferroni inequality). The Holm-Sidak test is a step-down "recursive reject", because it applies an accept/reject criterion on a sorted set of null hypothesis, starting from the lower p-value and going up to the acceptance of null hypothesis. For each comparison, the alpha value is set according to Sidak correction of Bonferroni inequality.

Dunn's test is the not parametric analog of Holm-Sidak multiple t-test. When you use the Kruskal-Wallis test, you know if there is a difference among your groups, but you can't apply the KWtest for each couple because the overall error is >alpha (Bonferroni inequality). By Dunn's test you can highlight where is the difference using multiple, stepdown comparisons. The algorithm requires the Statistics Toolbox..

The main function, TPOWER, will compute the power of a t-test given an effect size (d), sample size (N), and alpha. By giving N as an array the program can be used to plan sample size for an experiment. By setting the "PLOT" parameter to 1 the function calls plotpowfun, which plots the array N against power. By providing a desired power level, DESPWR, the program will also determine the minimum sample size needed to reach the desired power..

Permutation test of the null hypothesis that a set of data was sampled from a symmetric distribution with a particular mean. The test is based on a t-statistic and can be applied to situations in which a one sample or paired sample/repeated measures t-test is appropriate. Note, that this test is more general than parametric t-tests in that it does not assume that the data were sampled from a Gaussian distribution. This function can perform the test on one variable or simultaneously on multiple variables. When applying the test to multiple variables, the "tmax" method is used for adjusting the p-values of each variable for multiple comparisons (Blair & Karniski, 1993).

It calculates the Spearman rank correlation coefficient from 2 or more data sets, and the associated t-test and p-values. The code is adapted with major changes from the Numerical Recipes book ( Example: >> x = [1 2 3 3 3]'; >> y = [1 2 2 4 3; rand(1,5)]'; >> [r,t,p] = spear(x,y) >> [r,t,p]=spear(x,y) r = 0.8250 -0.6000 t = 2.5285 -1.2990 p = 0.0855 0.2848.

Estimates the exact statistical power of a performed Student's t test about mean(s). Here, according to Winer (1970) we use the exact power by the noncentral cumulative distribution function. It recalls you the statistical result of the test you should have arrived. Inputs: t - Student's t statistic (It is considered the estimated noncentrality parameter) df - degrees of freedom c - specified testing direction [1 = one-tailed(default);2 = two tailed]. alpha - significance level (default = 0.05) Outputs: -Specified direction test (Statistical result of the test you should have arrived). -Power.

Estimates the approximate statistical power of a performed Student's t test about mean(s). Here, according to Zar (1999) we use the approximation of power by the central cumulative distribution function. It recalls you the statistical result of the test you should have arrived. This power estimation is considered biased, for it is underestimated. However, it is presented for all those interested people. You can find the exact power estimation on the extpowerStudent m-file. Inputs: t - Student's t statistic df - degrees of freedom c - specified testing direction [1 = one-tailed(default);2 = two-tailed] alpha - significance level (default = 0.

This function can be used to perform multiple comparisons between groups of sample data. The Bonferroni correction is used to keep the total chance of erroneously reporting a difference below some ALPHA value. For example, consider an experiment with four patients. Their temperature is measured at 8AM, Noon, and 5 PM. This function can be used to test if there is a difference in temperature between 8AM and Noon, between Noon and 5PM, and between 8AM and 5PM..

Statastizard(c)2012 Nick Emblow is a program designed to guide its user into the right statistical test, perform the test, and report the results in a meaningful way.

The idea of this is that the user won't actually need to know that they are using a mann-whitney U over a t-test, for example - it just tests for normality and homoscedastic of variance, and decides which test to use, then reports the results.

Because time after time, people come to me with some test that they've done that they think "proves" something - when in reality they've either not done a comparative test to start with (ex.

G*Power 3 is a major extension of, and improvement over, G*Power 2 . It covers statistical power analyses for many different statistical tests like:
F test,
t test,
χ2-test and
z test families and some
exact tests

G*Power is offering five different types of statistical power analysis:
· A priori (sample size N is computed as a function of power level 1-ß, significance level a, and the to-be-detected population effect size)
· Compromise (both a and 1-ß are computed as functions of effect size, N, and an error probability ratio q = ß/a)
· Criterion (a and the associated decision criterion are computed as a function of 1-ß, the effect size, and N)
· Post-hoc (1-ß is computed as a function of a, the population effect...
