Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

q4 i? A large clustered RCT found no evidence that one year of chess lessons raised KS2 maths scores, with an effect size of 0.01 and a confidence interval spanning zero. → Jerrim et al. 2016
