The Spring 2016 Tutorials are:
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 email@example.com for a Qualtrics account. Please note the Boston College School with which you are affiliated.

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: 1) GIS data and technical support at Boston College; 2) Examples and demos using Census and Environmental data; 3). Options to get data and training will be also discussed. No prior knowledge of GIS is required.

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.

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 is part of 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
- Recent improvements in BC’s newest release of REDCap 6.10.1 including offline survey capabilities, text to voice capability, potential for using twilio.com SMS services (for an additional fee), improved field calculations and more
- How to enter data into RedCAP
- How to control RedCAP user access rights
- How to 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.

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.

This workshop provides an introductory demonstration of how to use NVIVO 11 for qualitative analysis. We will discuss the updates in NVIVO 11 from previous versions. NVIVO 11 can be used to manage large amounts of qualitative data, to code and re-code qualitative data, to keep an audit trail of the analysis process, and to support both individual researchers and research teams in discussing coding and analysis issues. This course is intended for beginning Nvivo users. and intermediate users who have had some exposure the methodologies and theories of qualitative analysis.
This workshop will include a demonstration (non-hands on) format:
- Qualitative research design
- Source Preparation
- NVIVO 11 Project Views (List, Navigation, Detail)
- Starting a project in NVIVO 11
Additional information on qualitative software and resources at Boston College will be presented.

We illustrate
- Two-Dimensional Graphics
- Basic Plots
- Axes and Annotation
- Multiple Plots in a Figure
- Three-Dimensional Graphics

We will continue the Modern Statistics Journal Club in the Winter/Spring Semester 2016. This group meets approximately once to month to explore new topics in the field of statistics. With the rapid change and growth in data analytical methods it can be difficult for a data analyst to keep their skills up to date. The Modern Statistics Journal Club has been created to provide the opportunity for data analysts in the Boston College community a place to explore new methodologies and an opportunity to learn from each other.
In the fall of 2015 we explored machine learning methods. This semester we plan to solicit topics from the participants. We will reserve rooms (one room only this semester) and send out the reading material at least one week before we meet. We will be meeting on Thursdays at 1 pm once a month. The dates are February 11, March 17, and April 21.
There are methodological considerations for all types of data collection whether quantitative, qualitative or mixed methods data are being used. Our emphasis will be on survey design for quantitative analysis (although the principles discussed will also be applicable to qualitative and mixed methods research and direct data input into an analytical tool). We will discuss how to design online surveys and databases to avoid a lot of pre-analysis data cleaning and data manipulation. We will also discuss best practices for HIPAA compliance and data security.

This tutorial is focused on transferring data across different formats. Research data often come in different formats, such as SPSS, STATA, SAS, Excel, Access, or text files. Researchers often encounter difficulties converting data from one format to another in order to use their prefered analysis tools.
This tutorial demonstrates how to perform conversions. We will also discuss how to resolve problems that might occur during the process, such as converting variable names. labels, values, data types, missing data, version compatibility, etc. Also we will show how to use StatTransfer to transform the data to different formats.
Students are encouraged to bring in their own data problems into the tutorial. We can then solve real problems while learning the ropes.
