Please, a question on how to use PSPP
Good morning, I need to apply the non-parametric test U Mann-Whitney by means of the PSPP, but I do not find this test on PSPP. Please, what can I do? Thank you very much in advance, best regards, P.R.D. -- Dra.

Re: Please, a question on how to use PSPP
You can perform this test using syntax in PSPP. Open a new syntax window, type the syntax (see below), and run it. The syntax is explained here: https://www.gnu.org/software/pspp/manual/html_node/MANN_002dWHITNEY.html, here: https://www.gnu.org/software/pspp/manual/html_node/NPAR-TESTS.html#NPAR-TESTS and here: https://lists.gnu.org/archive/html/pspp-users/2012-05/msg00043.html For example, if you have groups defined by values 1 and 2 in a variable called GROUP and you want to analyze variable SCORE, then you type: NPAR TESTS /MANN-WHITNEY = SCORE BY GROUP (1,2). If this isn't clear, please post more information about your problem or concern (or error message). -Alan On 6/15/2018 6:07 AM, Paloma Rohlfs Dominguez wrote: > Good morning, > > I need to apply the non-parametric test U Mann-Whitney by means of the PSPP, > but I do not find this test on PSPP.

Mann-Whitney U test
Dear Ms Rohlfs Dominguez, you are right that the Mann-Whitney U test and other nonparametric tests for two independent samples are still not implemented in the GUI of PSPP although you, me and others have been asking for it for several years. But fortunately, the U test can be computed if you write the syntax NPAR TESTS /STATISTICS=DESCRIPTIVES /MISSING=LISTWISE /MANN-WHITNEY = x BY y (1 2) in a syntax window / file of PSPP. x stands for your dependent variable. y stands for your independent, grouping variable. 1, 2 stand for the codes of the two groups. You have to replace x, y, 1 and 2 appropriately when you work with your data set.
