Data Analysis

SRG’s staff has advanced training in public health, epidemiology, statistics, psychology, and sociology. Staff will pull expertise from these disciplines when providing consultation and guidance on data analysis for your research. Some of our prior projects have estimated the prevalence of respiratory diseases among adults in California, determining the chronic disease burden among cancer survivors in California, and examining physical activity trends for partners such as the California Department of Public Health, the University of California, Los Angeles, and the Network for a Healthy California. We are also skilled at conducting analyses by subgroups and regions, as well as using small area estimation techniques.

SRG provides services, training, and consultation for the following:

Statistical Analysis

SRG research staff can analyze data in SAS, SPSS,  or other statistical software packages and has produced numerous reports, peer-reviewed publications and presentations utilizing a variety of statistical methods.

We can help you to examine complex health problems using data from surveys, health departments, hospitals, social services, and other sources.

Our staff has advanced training in statistics, epidemiology, psychology, and sociology, and can help you determine the best statistical methods to use with your data.

We can also provide analyses of large datasets to examine trends over time and small area estimation models.

Sophisticated Weighting Techniques

SRG employs sophisticated weighting procedures to take into account the complex design of a survey and so that the survey sample represents the population. These procedures include iterative proportional fitting (raking), weight trimming, and post-stratification.

We have created sampling weights for adult and child samples, as well as for surveys with landline and cell phone frames.

Weights can be created for split samples as well as for analysis of the combined dataset.

Qualitative Analysis

SRG researchers can systematically analyze qualitative data from focus groups, interviews, environmental scans, and other qualitative sources:

  • Coding of text and images
  • Identify themes and connections
  • Illustration of themes with quotes from coded text
  • Development of an explanatory framework

Geographic Information Systems (GIS)/Geocoding

Geographic data such as addresses can be geocoded by SRG research staff to develop x, y coordinates so that data can be linked with census tract, zip codes, cities, states, or other geographical zones.

Data Mining

Collection and analysis of large data sets to identify patterns, including social media mining and Electronic Medical Record (EMR) analysis.
