Hey,

As a part of the EA Israel's workshop project, I'm writing a presentation on measurement and evaluation of social impact, and I'm looking for material on the following topics:

 * Reliable and approachable materials regarding RCT execution and how to determine the representative sample of a study population

* How to evaluate  an intervention focused on subjective well being, in terms of comparing between SWB focused interventions and evaluating the impact of these types of interventions. 

Thanks in advance!
