Tutorials: Summer 2011
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 (email@example.com). 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 send email to firstname.lastname@example.org with the names of the tutorials that you are interested in attending.
The Summer 2011 tutorials are:
Qualtrics offers a way to create complex surveys without complicated programming. It offers survey design functionality that is more extensive than that offered by Survey Monkey. Qualtrics offers an extensive library of surveys and a number of options for encryption. Working within pre-defined templates, you can use several 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, SPSS, or other 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, and LSOE 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. Those community members not in A&S, CSON, CSOM, or LSOE 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, CSON, CSOM, or LSOE) or email@example.com to obtain a Qualtrics account prior to the tutorial.

For people who are already familiar with Qualtrics or who have attended the earlier introduction, we will cover some Qualtrics "bells and whistles." Topics covered include customizing surveys with HTML, branching, and other logic. We will also go into more depth about Qualtrics generated reports and how to customize them. We will discuss how to prepare the data that you have gathered from your Qualtrics survey for exporting to other statistical packages. Specific questions or topics of interest may be sent to firstname.lastname@example.org in advance of the tutorial.

This tutorial will explore the basic steps in constructing a model for confirmatory factor analysis with Lisrel 8.80. Confirmatory factor analysis (CFA) emphasizes the use of theory in measurement hypothesis testing, which is informed by the researcher's applied theoretical framework and empirical evidence from reliability analysis and exploratory factor analysis (EFA). This session will discuss the interpretation of reliability and EFA results on SPSS, and then examine CFA results from Lisrel. The goal of this tutorial is to introduce some of the methodology behind CFA analysis and provide some resources for beginning users to expand their knowledge on the topic.

This tutorial will provide a general discussion of qualitative research and a demonstration of recently released Nvivo 9. We will also discuss and compare Atlas.ti 6.2, and HyperResearch 3. Each of these software products has strengths and weaknesses when used for coding and analyzing qualitative data. However they can all be used, with planning and rigorous qualitative research methodologies, to eliminate the problems of managing large amounts of qualitative data. They can all be used to code and re-code qualitative data, keep an audit trail of the analysis process, and to support both individual researchers and research teams in thinking about coding and analysis issues. Specific topic requests may be sent to email@example.com in advance.

Boston College offers many sources and repositories of data for secondary research in the social sciences, education, nursing, economics, business and other disciplines. This workshop is particularly geared to researchers who need to access, analyze and manipulate data from BC's subscription data repositories.
This tutorial will help you:
- Find the data you need for your research or class project
- Learn about the Boston College collection of data resources in the Statistical Data Catalog
- How to download the data onto your desktop, including how to import into quantitative analytical tools such as SPSS.
- Tour of the Inter-University Consortium for Political and Social Research, a data archive that includes over 5,000 datasets.
We will also discuss the library's guides to key Business, Economics, Education, Health, and General U.S. and cross-national data sources. Topics may be customized based on attendees' research interests. Please contact firstname.lastname@example.org for more information.

Matrices are fundamental to MATLAB, and even if you are not intending to use MATLAB for linear algebra computations you need to become familiar with matrix generation and manipulation. In the MATLAB environment, a matrix is a rectangular array of numbers. Scalar and vectors are particular cases of matrices and in the beginning, it is usually best to think of everything as a matrix. The operations in MATLAB are designed to be as natural as possible and MATLAB allows you to work with entire matrices quickly and easily. This workshop will discuss:
- Matrix generation
- Subscripting and the Colon Notation
- Matrix and Array Operations
- Matrix Manipulation
- Data Analysis

MATLAB provides a powerful programming language, as well as an interactive computational environment. You can enter commands from the language one at a time at the MATLAB command line, or you can write a series of commands to a file that you then execute as you would any MATLAB function. Creating M-files and efficient use of operators, and flow control commands, are necessary for efficient programming.
This workshop will introduce:
- Relational and Logical Operators
- Flow Control
- Scripts and Functions
- Editing M-Files
- Working with M-Files and the MATLAB Path

The MATLAB environment provides a wide variety of techniques to display data graphically. Interactive tools enable you to manipulate graphs to achieve results that reveal the most information about your data. You can also annotate and print graphs for presentations, or export graphs to standard graphics formats. In this workshop we cover the basic use of MATLAB's most popular tools for graphing two- and three-dimensional data. We illustrate:
- Two-Dimensional Graphics
- Basic Plots
- Axes and Annotation
- Multiple Plots in a Figure
- Three-Dimensional Graphics
- Specialized Graphs for Displaying Data
- Saving and Printing Figures
Examples presented (m files) can be easily modified and applied to your specific experimental or model data.

Mixed Modeling is known by many names, such as Hierarchical Linear Modeling, Generalized Linear Modeling, Multilevel modeling and has been used by researchers in multiple social science disciplines such as social work, education, sociology, and nursing to capture neighborhood effects.The contextual impact that particular forms of memberships has on the individual can be better explained by the techniques of mixed modeling, when these memberships make a difference to outcomes of interest. Examples of this can be found in the clustering of classrooms, schools, demographic regions, occupations, or family systems. This tutorial will begin with a discussion on some of the updates to HLM, including their newest release since March 2011 of HLM 7. Sample data will be examined using HLM to identify fixed and random effects based on group membership, and these results will be replicated on Stata using the xtmixed command.
