Hi Brett, first of all, thanks for sharing the small project “Mobile Games A/B Testing with Cookie Cats” on DataCamp with all participants. There are rare materials covered AB testing online and I took a while searching for the worth ones. It turns out that the project is helpful using real dataset to practice and understanding AB testing method. I am first year MA statistical student studying at Columbia University. While doing the project, a few questions confuse me. When doing the sanity check, we wanted to make sure each group have the same number. So I also checked the p-value for the sample size and calculated the confidence interval. The result turns out that the confidence interval is not concluded p-value, which means there are significant difference between the players numbers. Therefore, our sanity check might fail to show there are same numbers in two groups. Thus, the following analysis could be wrong. My question is do we need to strictly following the CI rules when doing AB testing? And I was wondering if you could possibly share with me a biggest challenge when designing the AB testing? I appreciate it. Thanks. My email is [email protected]edu. Sincerely, Rae Cao

Hi Brett. Let me just first say that you have a great little app for converting csv to json. I've been searching quite some time for something like this. I work at PNC Bank, a large regional bank in Pittsburgh. I work in the Data Warehouse group and I'm trying to leverage a tool called "foamtree", which uses json. here is the link to the demos --> https://get.carrotsearch.com/foamtree/latest/demos/ I think you'll like this if you haven't discovered already. here is a link to the data-model api --> https://get.carrotsearch.com/foamtree/latest/api/#data-model and here is the link to the data-model api. I am so close to getting it into the right format from a csv using your tool but I still am not able to get there. I was wondering if you could possibly guide me with your tool to get the format required for foamtree. Thanks. my email is [email protected] Chris Esch
