This paper from the UK Cabinet Office describes how random control trials can be used to assess the effectiveness of public policy interventions.
- What is a randomised controlled trial?
- The case for RCTs - debunking some myths
- 1. We don’t necessarily know ‘what works’
- 2. RCTs don’t have to cost a lot of money
- 3. There are ethical advantages to using RCTs
- 4. RCTs do not have to be complicated or difficult to run
- Step1: Identify two or more policy interventions to compare
- Step 2:Define the outcome that the policy is intended to influence
- Step 3:Decide on the randomisation unit
- Step 4:Determine how many units are required for robust results
- Step 5: Assign each unit to one of the policy interventions using a robustly random method
- Step 6: Introduce the policy interventions to the assigned groups
- Step 7: Measure the results and determine the impact of the policy interventions
- Step 8: Adapt your policy intervention to reflect your findings
- Step 9: Return to step 1
