The best thing you can do is compare it to another study, since turning 0.06 standard deviations into a percentage of happiness isn’t going to be that telling.

The best thing you can do is compare it to another study, since turning 0.06 standard deviations into a percentage of happiness isn’t going to be that telling. In general, 0.2 is considered a small effect. So 0.06 is quite small — likely not a practically noticeable change in well-being. But impressive to me when I compare it to effect sizes of therapy interventions which can lie around 0.3 for 12 weeks. Quote: > “50 randomized controlled trials that were published in 51 articles between 1998 and August 2018. We found standardized mean differences of Hedges’ g = 0.34 for subjective well-being, Hedges’ g = 0.39 for psychological well-being, indicating small to moderate effects, and Hedges’ g = 0.29 for depression, and Hedges’ g = 0.35 for anxiety and stress, indicating small effects.” (Source: The efficacy of multi-component positive psychology interventions, 2019 — https://www.researchgate.net/publication/331028589_The_Efficacy_of_Multi-component_Positive_Psychology_Interventions https://www.researchgate.net/publication/331028589_The_Effic...)
