Roadmap to Data Analysis

This series introduces Survivor of Torture programs to essential concepts and methods for data analysis, and demonstrates the use of various tools. The series objectives are to:

  • Provide an introduction to basic statistical procedures relevant to SOT agencies
  • Provide a foundation to analyze and interpret data on clients, services, and outcomes
  • Provide an introduction to the use of available tools for basic analysis of data
  • Provide an understanding of the limitations of statistical analysis, and guidelines for agency staff about when to seek statistical consultation

 

Intro to Roadmap to Data Analysis Series

The introduction to the Roadmap to Data Analysis series, which is designed for staff members at torture treatment programs who find that they must do evaluation and data analysis work without the relevant training.

Roadmap to Data Analysis 1: Intro to Statistical Thinking

The first module in the Roadmap to Data Analysis series, this short video covers the basics of statistical thinking and inference, describes the concepts of “population” and “sample” in quantitative research, explains the process by which inferences can be made to a population based on a sample, and clarifies what "hypothesis testing” and “probability value" mean in a data analysis context.

Roadmap to Data Analysis 4: Comparing Averages - The t Tests

The fourth module in the Roadmap to Data Analysis series, this short video helps you determine which statistical test to use for comparing averages between two groups, describes the differences between the independent t test and dependent (paired) t test, and demonstrates how to use a t test calculator with example data, and interpret results.

The Student's t-test is used in this video: http://www.healtorture.org/content/paired-t-test-calculator-tool

Roadmap to Data Analysis 6: Comparing Continuous Variables - Correlation

The sixth module in the Roadmap to Data Analysis series, this short video describes the type of data that are relevant for a correlation analysis, explains the basics of how correlation works, demonstrates how to use a correlation calculator or Excel to conduct a correlation analysis with sample data, and provides guidance on interpreting and reporting results.

This calculator was used to obtain both the r and p values in this video: http://www.healtorture.org/content/pearson-r-and-p-value-calculators

If you are familiar with Excel, you can also use the step-by-step instructions available here to obtain the Pearson's r value: http://www.healtorture.org/content/correlation-calculation)
