hello folks, when running experiments in GrowthBook, how are outliers treated? so for example something like spend (similar to order value) that is extremely high and happens only on A, is that something that is excluded when calculating exp results?

Hi Yaniv. We don't automatically correct for outliers, but we do have the ability for you to adjust for this. You can add a capped value to adjust for this: https://docs.growthbook.io/app/metrics#capped-value

got it, thanks! ideally I would prefer to have something that removes values based on percentiles, rather than caps. we can achieve that in the metric queries as well @fresh-football-47124

thanks for the feedback. It's really tricky to make something work for all cases. I'll bring it up with the team

absolutely, though if it's not supported, this is something relatively hard to figure out for small orgs with limited proficiency in statistics 🙂
