Spring 2015 Tutorials
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 (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 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 firstname.lastname@example.org with the names of the tutorials that you are interested in attending.
Please note that the locations of the tutorials varies.
The Spring 2015 Tutorials are:
This tutorial is geared towards Boston College Principal Investigators, researchers and research project team managers. REDCap stands for Research Electronic Data Capture. REDCap is a web based, data collection, database management system that was originally developed at Vanderbilt University, initially for medical research. REDCap is now overseen by a consortium of academic research partners in the United States and throughout the world. Boston College has recently joined the REDCap consortium.
In this introduction to REDCap we will discuss:
- How to request a REDCap project at Boston College
- How to make sure that your RedCAP project complies with the mandates of your project's IRB approval
- How to create basic data collection forms
- An introduction to best practices for setting up your REDCap project
- How to enter data into RedCAP
- How to control RedCAP user access rights
- How to create ad hoc reports and export your data
Prior to the class, Research Services will create a TEST project for teaching and learning purposes for each class participant. Research Services staff are also available to meet with members of the Boston College community to discuss individual REDCap projects.

Qualtrics offers a fairly intuitive Graphical User Interface 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. Strength of Qualtrics is its panel feature for repeated polling, built in social media sharing functions, and accessibility checker. Working within pre-defined templates, you can use many different types of questions, including text, multiple checkboxes, sliders, single-answer radio buttons, and Likert scales. Qualtrics offers extensive branching functionality.Once the survey is completed, data can be downloaded into a format that can be used with a variety of quantitative and qualitative analysis programs. Qualtrics also offers foreign language functionality.
This tutorial will demonstrate how to create a survey in Qualtrics and also include a section on research protections and informed consent with respect to online survey development, distribution, and analysis.
BC community members who do not already have a Qualtrics account may contact Rani Dalgin at email@example.com for a Qualtrics account.

Geographic Information Systems (GIS) are used for visualizing, managing, creating, and analyzing geographic data. Such applications are widely used in academia, private industry and government agencies. Available GIS technologies are used to perform various tasks, from simple to advanced, including: mapping, geographic analysis, geostatistics, data editing, compilation, management and visualization.
This session will introduce users to:
- GIS data and technical support at Boston College
- Examples and demos using Census and Environmental data
- Options to get data and training will be also discussed.
No prior knowledge of GIS is required.

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.

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.

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.

Linear Probability Model, Logit and Probit Models, and other Approaches to Limited Dependent Variables
Stata is a powerful, yet easy to use, statistical package. This hands-on tutorial is designed to provide an overview of how to implement sound statistical and econometric analysis in presence of limited dependent variables. The emphasis in this tutorial is on techniques to estimate model where the response variable is restricted to a binary choice, integer values or ordered values on a Likert-type scale, such as survey data. Basic knowledge of Stata is required.
- Linear Probability Model, Logit and Probit Models
- Marginal Effects
- Ordered Logit and Probit Models
- Count Data Models

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; and how to download the data onto your desktop, including how to import into quantitative analytical tools such as SPSS. Get a 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. We will also discuss best practices for curation of both primary and secondary research data. Topics may be customized based on attendees’ research interests. Please contact firstname.lastname@example.org for more information.
