This wiki has been created to provide you with all sorts of statistics tutorials to guide you through the standard statistical analyses common to hypothesis testing in the social sciences. Examples are geared toward organizational, business, and management fields. AMOS, SPSS, Excel, SmartPLS and PLS-graph are used to perform all analyses provided on this wiki. This wiki is not exhaustive, or even very comprehensive. I provide brief explanations of concepts, rather than full length instruction. My main focus is on providing guidance on how to perform the statistics. This is very much a mechanically oriented resource. For more comprehensive instruction on the methods demonstrated in this wiki, please refer to Hair et al 2010 (Multivariate Data Analysis), as well as to the powerpoint presentations offered for most of the topics. I hope you find the resources here useful. I will likely update them from time to time.

This teaching material has been developed as part of a quantitative social science method sequence aimed to prepare Doctor of Management students for their quantitative research project. These students are working executives who carry out a rigorous quantitative project as part of their research stream. Examples of these projects and examples of how to report results of quantitative research projects in academic papers can be found at in the DM Research Library.

  • You may find this set of Excel tools useful/necessary for many of the analyses you will learn about in this wiki: Stats Tools Package Please note that this one is the most recently updated one, and does not include a variance column in the Validity Master sheet. This is because it was a mistake to include variances when working with standardized estimates. Also, most browsers now block the download of xlsm files like this one. So, you'll probably need to use Chrome to download it if your browser doesn't work. You might also have to tell Chrome to let you keep the download if it asks you whether you want to discard it. Windows also now blocks xlsm files. So after you download this file, you'll need to right-click it, go to properties, then check the 'unblock' box to allow it. Then even after you open it, you'll need to click the popup that says 'allow macros'.
  • You may also find this basics tutorial for AMOS and SPSS useful as a starter.

Here are some links to the datasets, and related resources, I use in many of the video tutorials.

The materials and teaching approach adopted in these materials have been developed by a team of teachers consisting of Jagdip Singh, Toni Somers, Kalle Lyytinen, Nick Berente, Shyam Giridharadas and me over the last several years. Although I have developed and refined much of the material and the resources in this Wiki, I am not the sole contributor. I greatly appreciate the work done by Kalle Lyytinen (Case Western Reserve University) , Toni Somers (Wayne State University), Nick Berente (Notre Dame University), Shyam Giridharadas (University of Washington) and Jagdip Singh (Case Western Reserve University) who selected and identified much of the literature underlying the materials and also originally developed many of the Powerpoint slides. They also helped me refine these materials by providing useful feedback on the slides and videos. I also appreciate the contribution and help of Jagdip Singh (Case Western Reserve University), who is the owner of the Sohana and Bencare datasets used in the examples and which are made available below. I also acknowledge the continued support of the Doctor of Management Program at the Weatherhead School of Management at Case Western Reserve University, Cleveland, Ohio for their involvement, support, and sponsoring of this wiki, as well as to Brigham Young University for encouraging me in all my SEM-related endeavors.
