Quantitative Data analysis support
The SSDL supports researchers using quantitative data in a number of ways. We provide general assistance in formulating research questions, identifying secondary data sets that can help answer those questions, as well as in figuring out the appropriate analytical techniques for the problem. We can help you use several quantitative data analysis software packages. Currently, we support SPSS, Stata, AMOS (for structural equation modeling), and HLM (for hierarchical linear modeling). We also can provide very basic assistance with SAS.
Quantitative Brown Bag Discussion Series
Sample of Past Meetings Descriptions:
Randomized Experiments in the Social Sciences
In this presentation, Temple University's own Kevin Arceneaux, associate professor of political science, will discuss experimental methods in both laboratory and field settings. Using examples from his own work, he will highlight the benefits, limitations, and challenges involved in using experimental methods to answer social science research questions.
Dr. Arceneaux investigates the effects of campaign advertisements and endorsements, the factors that facilitate and limit the persuasiveness of political rhetoric, and the impact of the hyper-choice media environment on public opinion. Risking oversimplification, one could say he watches people watching political TV. In each of these projects, Dr. Arceneaux aims to apply theories developed in psychology, evolutionary psychology, and neurobiology to the study of political phenomena.
Come to the lunch, and see what else you could worry about if you're weren't worrying about endogenous variables.
Please RSVP to email@example.com to let us know if you plan to attend. If you have any questions or suggestions for future Brown Bag topics, email the SSDL or call us at 215-204-5001.
Using PhilaMetroMapper on The Philadelphia Metropolitan Indicators Project Web site.
Researchers studying communities in the Philadelphia Metropolitan Statistical Area now have online access to comprehensive administrative data on a municipality by municipality basis. This presentation demonstrates easy ways to both access the data and create maps and graphs that illustrate findings in an engaging and intuitive manner. This unique tool aggregates data into useful geographic units, providing a new, user-friendly entry point to data that has previously been unavailable or very difficult to access.
Using Multilevel Models for Longitudinal Data Analysis
Social scientists heavily use longitudinal data – multiple observations collected over time from the same subjects – to make causal inferences and to describe human development. Unfortunately analyzing longitudinal data is not as straightforward as analyzing cross-sectional data. Multilevel modeling (also known as hierarchical linear modeling) is a flexible data analysis technique well suited for longitudinal designs. In this brownbag, Josh Klugman (Sociology) introduced attendees to the logic of multilevel modeling and provided an overview of the different longitudinal applications of this technique.
Verbalizations While Reading and Learning
For several years, Dr. Jennifer Cromley has worked with data that are verbalizations by participants while learning or while reading. This think-aloud protocol methodology yields counts of coded verbalizations. This methodology is widely used in cognitive and educational psychology. Typically, participants differ in the total number of coded verbalizations. Therefore, researchers convert the raw frequency data to proportions of utterances (or behaviors, etc.) and analyze these proportions. The data analytical quandary for this type of research is that all of the typically-used methods have very low statistical power. The question is “which statistical technique is better suited for this analysis?
Quantifying Geographical Effects on Human Behavior
There are a number of researchers at Temple who are trying to model human behavior at an individual level (i.e. not aggregated) based on geographic characteristics of where individuals reside: whether someone commits a crime, makes healthy lifestyle choices, etc. These analyses are challenging, not just because of the technical aspects of choosing the right analytical technique for spatial data, but because of the mismatch between theories of how environment affects behavior and our ability to quantify environmental characteristics and their relationship to individuals. Sometimes researchers face negative results – perhaps because of the mismatch between theory and implementation. Jeremy Mennis, Associate Professor at the Department of Urban Studies will invite a panel to discuss ways we can more accurately match substantive theories of the affect of geographic characteristics on human behavior with the available representational and analytical techniques necessary to adequately test such theories.
Longitudinal Data Analysis.
A team of researchers from the Psychology Department who are studying juvenile offenders will present a research problem requiring longitudinal analysis. Other researchers attending the session, including several with extensive experience with longitudinal analysis, will offer suggestions regarding approaches to this problem.
Joanna Lee, Graduate Student with Larry Steinberg, Psychology Department, will be presenting a missing data problem affecting her analysis of the relationship between police maltreatment and psychological distress experienced by African-American youth involved in the juvenile justice system.
We plan to identify in advance, faculty, graduate students, or research scientists with a particular methodological and/or analytical challenge. For the first seminar we have asked a team of graduates students working with longitudinal data to prepare a ten to fifteen minute presentation that describes the research question, the data (and any problems with the data), their thinking about how they want to analyze the data, and any issues or problems they are already aware of with respect to the analysis.
Following the presentation, an appointed “mentor”, who is knowledgeable about the methods under discussion, will summarize the problem, and then open up the floor to researchers in the room who will offer suggestions about approaches to the problem. There will be questions of clarification and conversation between the presenters and the panel of experts. At the end of the discussion, the “mentor” will summarize the challenges and propose one or more approaches to the problem.
Join QuantSIG: The Quantitative Data Special Interest Group
QuantSIG is a listserv for quantitative researchers at Temple University. Please email the ssdl if you are interested in joining the list. This list will provide announcements about training sessions, workshops, lectures and presentations of interest to "counters," as well as being a place for questions and discussions of problems experienced in current research.
