Information Technology Services
Research Services offers tutorials and workshops on a variety of topics. Each semester, we present a series of tutorials. If you have suggestions, please contact us (firstname.lastname@example.org). We will also give customized tutorials, and we are available for advanced topics and consulting.
The tutorials are available to all members of the BC community. There is no cost for the tutorials.
To register, please go to our on-line tutorial registration page at: capricorn.bc.edu/tutorials. You will be asked to sign in using your BC username and password to register. You can also use this web page to change the tutorials you signed up for. You can also register by sending mail to email@example.com with the names of the tutorials that you are interested in attending.
Please note that the locations of the tutorials varies.
The Spring 2014 Tutorials are:
Qualtrics offers a way to create complex surveys without complicated programming or coding. Qualtrics offers extensive documentation, free online tutorials, an extensive library of surveys and options for encryption and anonymity, and excellent customer support. Qualtrics also offers foreign language functionality. Working within pre-defined templates, you can use many different types of questions, including text, multiple checkboxes, sliders, single-answer radio buttons, Likert scales. Qualtrics also offers extensive branching functionality. Once the survey is completed, data can be downloaded into a format that can be used with Excel, Stata, SPSS, Nvivo, HyperResearch or Atlas.ti or other quantitative and qualitative analysis programs.
This tutorial will also include a section on research protections and informed consent with respect to online survey development, distribution, and analysis. BC’s School of Arts & Sciences, CSON, CSOM, LSOE, and GSSW have purchased annual Qualtrics licenses that are available for use by faculty, staff, and students in those schools. People not in these schools are also welcome to attend this tutorial. BC community members not in those schools may register for a limited free Qualtrics account at qualtrics.com. They may also obtain free access to Qualtrics online tutorials and help articles. It is recommended that you contact your school (A&S (firstname.lastname@example.org), CSON (email@example.com), CSOM, (firstname.lastname@example.org), GSSW (email@example.com), or LSOE (firstname.lastname@example.org) to obtain a Qualtrics account prior to the tutorial.
Customized Qualtrics training at all levels is available for classes as well as individual researchers by contacting email@example.com.

Mixed modeling, also known as multi-level modeling or sometime hierarchical linear modeling, is an essential tool in many research areas. In biomedical research most designs are longitudinal, in social sciences there are often clusters of data such as students within classrooms within schools. Many familiar methods such as ANOVA or regression assume that all observations are recorded independently. Having clusters of correlated data violates this assumption and makes these methods invalid. Mixed Modeling is an extension of regression that allows us to correctly model correlated data. This tutorial is designed to give an introduction to linear mixed modeling. We will focus on situations and designs where these methods are required, the dangers of using the wrong methods, and interpretation of the results that are standard across most statistical software packages.

Researchers in the social sciences are often interested whether the relationship between two variables might vary for different groups or within different settings. Moderating variables allow researchers to model these types of relationships. This tutorial will provide an introduction to moderating variables. It will describe how to create moderating variables, how to correctly analyze them within a regression model, and how to interpret moderation effects. Demonstrations will be conducted in both SPSS and in Stata.

R is widely used free statistical software. To take advantage of R’s flexible output and graphics, packages are actively being developed to that interface R with other programs such as M-plus. The rapid growth of R means that knowledge of this software will be essential to researchers doing complex statistical analysis. This tutorial will explain how to download and install R (it’s free!!), learn basic operations. We will focus on a couple concrete examples so that attendees will get familiar with the R environment.

As the most common methodology in statistical analysis regression is an important tool for any modern researcher. This course is intended as an introduction to standard or linear regression. We will focus on estimation methods, identifying and validating model assumptions. We will also focus on hypothesis testing for regression estimates and statistical model building. We will use R software but the goal of the course is to learn concepts and is not intended as a tutorial any specific software. Note: The mixed modeling course is a natural sequel to Introduction to Regression.

The Libraries and Research Services will provide a critical overview of “best practices” for research data management, including development of “data management plans”. Funders (government agencies, in particular) and journal publishers are increasingly requiring submission of dthese plans incorporating all of these practices, along with placing greater emphasis on sharing and long-term preservation of research data. You’ll learn how to safe-guard your data through recommended practices for naming, file format choice, file organization, storage, backup and documentation, as well as information about valuable university data analysis and support services. You’ll learn about options for long-term archiving of your data and data sharing, including discovery of quality social sciences data repositories and creation of metadata to enhance discovery of that data. You’ll also learn how to cite your data/data sets, further enhancing the discoverability and impact of your work.
