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 Fall 2015 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 firstname.lastname@example.org for a Qualtrics account. Please note the Boston College School with which you are affiliated.

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
- 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.

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.

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.

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

As the ability to collect, store, and process data has grown with the digital revolution, the field of statistics has had its own revolution to keep up with the new demand. Although classical methods which have the focus of a statistical education through the early 2000’s remain at the center of statistical inference, they are no longer sufficient for many modern data analysis applications. Outside of traditional inference with known group structures many modern analysis are focused on finding unknown structures with large datasets. These applications have many names, originally called data mining, but they are now more generally referred to as statistical learning methods.
Given the ubiquity of these types of problems and the success data analysts have had using these methods it is important for the modern statistician to keep current with these methodologies. The goal of this journal club is to provide a place for modern researchers and data users to help each other keep current with new methodologies and learn from each other’s expertise and intuitions. For the fall semester we will meet Thursdays at 1:00 pm one time per month for one to two hours depending upon interest. To get things started during this semester we will read chapters from "The Elements of Statistical Learning" by Hastie, Tibshirani and Friedman. This book is available as an e-book from the Boston College Library so all participants will have free access. Research Services will provide a monthly reading list, meeting rooms, and reminders.
Tentative meeting dates are September 24, October 22, November 19 and December 10 from 1:00 - 2:00. If interested, please sign up, we will add you to an email list.
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.
