Research Resources

Our library of practical resources is available for researchers undertaking randomized evaluations and those teaching the technique to others. The resources presented here are curated by J-PAL in partnership with Innovations for Poverty Action (IPA).

Poster: Real-World Challenges to Randomization and Their Solutions

A poster that summarizes the key takeaways and visuals from the guide: Real-World Challenges to Randomization and Their Solutions.

Stata 102

In this Stata module, you have some Stata experience (say in a college class) but would not consider yourself particularly comfortable with the program. You are very familiar with the following concepts:

  • Descriptive commands such as summarize, tabulate, and list
  • Conditions: if, and (&), and or (|) 
  • Data manipulation commands such as generate, replace, and drop

You are likely somewhat familiar with:

  • Creating and writing do-files
  • Sorting and saving datasets

Stata 103

You have used Stata for a major school project or in a work environment. You feel comfortable with all basic commands and are very familiar with the following concepts:

  • Locals (note: this is absolutely necessary!!)
  • The foreach command
  • Naming and labelling variables
  • Variable types (strings, numerics)
  • Importing data through use, merge and append

You are likely somewhat familiar with:

  • Loops using varlist or numlist
  • by
  • egen

Stata 104

This is an advanced, applied, Stata class. You should be quite comfortable using Stata. You are very familiar with the following concepts:

  • Loops with varlist and numlist, as well as while loops
  • The if command (distinct from the if qualifier)
  • N and _n
  •  by
  • egen

You are likely somewhat familiar with:

  • capture and assert
  • Saved results such as r(N), r(levels

Administrative Steps for Launching a Randomized Evaluation in the United States

A checklist that provides guidance on the logistical and administrative steps that are necessary to launch a randomized evaluation that adheres to legal regulations, follows transparency guidelines required by many academic journals, and complies with security procedures required by regulatory or ethical standards.
