    Doing Statistics with SPSS. (2002)
    London :SAGE Publications, Limited,
    Details
    Schlagwort(e): Social sciences - Statistical methods - Computer programs. ; Electronic books.
    Beschreibung / Inhaltsverzeichnis: Doing Statistics With SPSS is derived from the authors′ many years of experience teaching undergraduates data handling using SPSS. It assumes no prior understanding beyond that of basic mathematical operations and is therefore suitable for anyone undertaking an introductory statistics course as part of a science based undergraduate programme.
