#product-design-strategy is starting [a research project about mobile contribution](https://docs.google.com/document/d/1JDWXquL5sEZMr-9Wb2Cp_YNXljQBr467XBDa2HNCWKQ/edit).
They've identified the following needs:
* Overall data on how many only-mobile and partly-mobile editors there are. A histogram of editor count by mobile edit proportion is probably the right deliverable.
* Random samples of 200 mobile edits from each of the English, Czech, Korean, French, and Hindi Wikipedias for manual analysis.
** On each wiki, 160 should be mobile web edits, 20 should be Android edits, and 20 should be iOS edits.
* A selection of users Abbey can email for the survey. The population is (1) English Wikipedia editors (2) with email addresses (3) who have made at least 5 edits (4) who have edited in the past 90 days. The stratification by region, platform, and experience is described in [this spreadsheet](https://docs.google.com/spreadsheets/d/10-GsYLH3zwMydMEXYx_CKdjDlx1Z4gm5RQu8yMG4YmM/edit?ts=5bd77d84#gid=0). The data should be:
** separated into two files based on experience
** tagged with user name, exact edit count, and user age
** uploaded into Qualtrics for @aripstra and @egalvezwmf to use.
