Growth/Analytics updates/Welcome survey initial report/vi

As part of the Growth team's "Personalized first day" project, we deployed the Welcome Survey to Czech and Korean Wikipedias on November 19, 2018, shortly after 19:00 UTC. The objective of the survey is to gather some initial information about new users so that we can personalize their first day on the wiki and help them achieve their goals. Before deploying, we published an experiment plan detailing what we will measure and why. This page is our team's initial report on survey results, and will be followed with more detailed analyses that address the various questions from the experiment plan.

In this report, we give a quick overview of the survey and its responses based on accounts registered between deployment and end of day (UTC) on December 17, 2018. We have calculated neither confidence intervals nor statistical significance of these results, and are not making claims about there being significant differences (e.g. between the two Wikipedias, or between groups of users). We have also not yet crosstabbed survey questions against each other or analyzed them alongside the EditorJourney data. Instead, we present these as preliminary findings and discuss some potential steps these findings might suggest, and will be doing a more thorough analysis in the upcoming quarter.

Toplines

 * Most users respond to the survey, giving it high response rates of 67% and 62% in Czech and Korean Wikipedias, respectively.
 * We are not currently concerned that the survey is causing new users to leave the site.
 * The most common reason for creating an account in Korean Wikipedia is to read articles—not for editing (29%). This is different than in Czech, where 18% give that response. The high numbers here may represent an opportunity to educate those users that it is possible and easy to edit Wikipedia.
 * The majority of respondents in both languages have not edited Wikipedia before (51% in Czech and 63% in Korean). But these percentages also mean that a large number of people have edited before (either anonymously or with a different account), and therefore may have some knowledge of how to edit.
 * Korean respondents were much more likely than Czech respondents to type in their own custom topics, as opposed to selecting only the pre-populated options. 28% of Korean respondents added their own topic, compared to 9% of Czech respondents.
 * Surprisingly large numbers of respondents said they are interested in being contacted to get help with editing: 36% in Czech and 53% in Korean. This is a strong affirmation that the potential and desire for human-to-human help exists. The respondents are an actionable list of users for outreach.
 * Few additional people add an email address who did not add one during account creation. The numbers are large enough that the option is productive (6% in Korean and 7% in Czech), but small enough that we could consider better appeals to encourage adding an email address.

Background
The original motivation for this survey was to collect information on users that we can use to personalize their experience. Read here about our thoughts on how to take action on this data in the next phase of this project.

During the four weeks after deployment, the survey was shown to a randomly-selected 50% of those who register a new account on the target wikis (meaning that it is not shown to users who already have an account on a different wiki, so called "autocreated users"). This A/B test between a survey group and a control was chosen so that we could determine if the survey leads to a lower proportion of users making their first edit within 24 hours of registration (what we call "editor activation"). An analysis of the results of that experiment is forthcoming.

A quick reference to what the survey looks like and the questions it contains is available in a mockup here. The survey is displayed in the Czech language and Korean language on those respective wikis.

Response rate
On Czech Wikipedia, we have shown the survey to 669 users, and on Korean Wikipedia to 836 users. When the user sees the survey, they have a series of questions to fill out, all of which are optional. They can then submit the survey by clicking "Finish" (even if they have not responded to any questions), discard their responses by clicking "Skip this survey", or take some other action that leaves the page or site, such as clicking on a link in the left navigation or closing their tab. We call this latter action "abandonment". The distribution between these actions for the two wikis is as follows: Table 1 shows that most of the users submitted the survey, which is great! As we will see below, users also answer our questions (rather than submit a survey with no answers). The abandonment rate appears to be fairly high, and at first we were concerned this meant that the survey was causing users to leave the website entirely, which would be a counter-productive outcome. To look into this, we dug into the data captured via our team's "Understanding first day" project, which gathers data on what new users view during their first 24 hours. We found that in Czech, only 47 users (7.0%) left the site, while in Korean it was only 99 users (11.8%). Both of these proportions are below the thresholds we had set for whether to change the survey or turning it off. This question will be answered more conclusively when we analyze the control group's rate of abandoning the site after account creation.

It is also possible to split the response rates by whether the account was created on the desktop or mobile site, but we find that the proportions are generally similar.

Câu hỏi đầu tiên của chúng tôi hỏi tại sao người dùng tạo tài khoản và cung cấp một số tùy chọn, cũng như tùy chọn "Khác" trong đó người dùng được cung cấp trường văn bản để giải thích thêm. Đối với hai Wikipedias mục tiêu của chúng tôi, các câu trả lời được đưa ra như sau, với tỷ lệ dựa trên số người trả lời trong mỗi ngôn ngữ: Điều đầu tiên cần lưu ý có lẽ là tùy chọn thường xuyên nhất là khác nhau giữa hai ngôn ngữ. Trong tiếng Séc, nó đang tạo ra một bài viết mới được lựa chọn bởi 32,6% số người được hỏi, trong khi bằng tiếng Hàn, nó đang đọc (28,8%). Trong cả hai ngôn ngữ, tùy chọn khác là thứ ba trong danh sách, việc đọc được lựa chọn bởi 17,5% số người trả lời tiếng Séc và tạo ra một bài viết mới bằng 19,7% bằng tiếng Hàn. Thật thú vị khi biết rằng việc đọc Wikipedia thúc đẩy rất nhiều việc tạo tài khoản, vì việc có một tài khoản không thay đổi đáng kể trải nghiệm đọc. Điều đó có thể chỉ ra một sự hiểu lầm xung quanh việc tạo tài khoản, nhưng cũng có thể là một cơ hội để thu hút người dùng cả với tư cách là độc giả và biên tập viên tiềm năng.

Thêm thông tin vào một bài viết luôn là lựa chọn thứ hai trong cả hai ngôn ngữ và có tỷ lệ tương đương khoảng 25%. Điều tương tự cũng xảy ra đối với việc sửa lỗi chính tả hoặc lỗi, luôn đứng thứ tư trong danh sách với khoảng 17% phản hồi.

 * No, other reasons
 * I don't remember

The second question asks whether the user has edited Wikipedia before and lists five potential answers. Some users also submit the survey without responding to this question. Table 3 below gives an overview of the responses, and again proportions are based on total number of survey responses. In both languages we find "No, I didn't know I could edit Wikipedia" is the most frequent option, and that a majority of respondents say they had not edited Wikipedia before (combining both "no" options: Czech: 50.5%; Korean: 63.2%). Regarding the "No, I didn't know I could edit Wikipedia" response, it makes sense that many people would give this answer given how many say they are creating their account for the purpose of reading. But we were also surprised that the number was quite so high. One hypothesis is that the question might be interpreted to mean different things by different respondents. One possible interpretation is "No, I didn't know I could edit Wikipedia until this survey question pointed it out", and another is "No, I didn't know I could edit Wikipedia until recently, but once I discovered that I could, I decided to create this account." We will learn some more about this question once we make cross-tabulations against the other questions, and we can consider clearer phrasings of these responses in the future.

It is also worth noting that the order of the responses is the same across both languages, and that it is different from the order the options are shown to the user. This means that the respondents did not simply choose the first answer in the list when responding, but are instead actively letting us know that they haven't edited Wikipedia before.

Select some topics you may wish to edit
''People can edit Wikipedia articles on topics that they care about. We've listed a few topics below that are popular for editing. Select some topics that you may wish to edit:''

Explicitly listed as checkboxes: Arts, Science, Geography, History, Music, Sports, Literature, Religion, Popular culture.

Available in a typeahead dropdown menu: Entertainment, Food and drink, Biography, Military, Economics, Technology, Film, Philosophy, Business, Politics, Government, Engineering, Crafts and hobbies, Games, Health, Social science, Transportation, Education.

The third part of the survey asks the respondents to select some topics that they may wish to edit. Nine topics are shown as checkboxes, and another eighteen topics show up when the user clicks on or types in the field. The field is free-form, allowing respondents to add additional topic. Respondents may choose and add as many topics as they like.

This analysis only covers the suggested topics. Future analyses will address the user-supplied topics, which require translation before they can be analyzed. We show one table below for each language. The table identifies the way a user can select a topic as either "checkbox", meaning it is one of the nine checkboxes; "prefilled", meaning it is one of the eighteen pre-filled topics found in the free-form field; or "other", meaning it is a topic added by the respondent.

We can see that the dominating topics are all the ones listed in the checkboxes. The least frequent checkbox is selected by 20.8% of respondents, while the most frequent topic in the free-form field is only chosen by 3.5% of respondents. It is noteworthy that respondents are selecting multiple topics, as opposed to just one.

We see a similar trend in Korean as for Czech: the checkboxes are dominating when it comes to selecting topics, although the difference between the least popular checkbox and the most popular pre-filled topic is smaller (11.0%) in Korean than in Czech (17.3%).

Are you interested in being contacted to get help with editing?
''We are considering starting a program for more experienced editors to help newer users with editing. Are you interested in being contacted to get help with editing?''

We find that in both languages, a surprisingly large number of users are interested in being contacted. 164 users in Czech (36.4% of all survey respondents) and 273 users in Korean (52.7%) answered "yes" to that question. This means that there's clearly interest among new users to get help to edit Wikipedia, and that this is a potential venue for community outreach. When we dig deeper into the survey responses, we will also compare the responses to this question with the answer to the question of whether the user had already edited Wikipedia, as well as why they signed up to create an account.

Adding an email address
Users who did not add an email address during their initial account creation are given a second opportunity to add their email address in the survey. We find that very few users do so, only 13 on Czech Wikipedia, and 20 on Korean. This corresponds to 6.5% of Czech users who did not already have an email address when shown the survey, and 5.7% of the Korean users.

Repeat survey responses
Though there is not an explicit workflow for doing so, users can take the survey multiple times by revisiting the survey URL. We only store their most recent responses, meaning that we regard their most recent answer to accurately reflect their interests and opinions. At the same time, we store a count of how many times they have responded/skipped. Table 8 below shows how the number of responses is distributed, where the proportion is out of all users who either saved or skipped the survey. We can see that it's relatively rare that users take the survey multiple times, and if someone does, it's typically only one more time. This means that we see little reason to discard responses based on users taking the survey multiple times and potentially changing their answers.

Sanity checks
We have also run various sanity checks on our data in order to ensure that things are working properly. For example, we have calculated the distribution of users assigned into the survey and control groups, which ideally should be 50/50. This also turns out to be the case, overall on Czech Wikipedia the proportions are 49.7%/50.3% survey/control, and on Korean Wikipedia it is the other way around. We do find some variation when accounts are split into registrations from desktop and mobile (e.g. that it's 47/53 in some cases), but not enough to warrant a concern that the randomization has led to imbalanced or biased groups.

While working on this report, we have not yet dug carefully into the data to determine if the responses appear to be truthful. For example, if a user answers that they did not know they can edit Wikipedia but also says they had edited Wikipedia many times, we should most likely discard their answers to at least both those questions, potentially the entire survey. This is noted and will be done as part of a more thorough examination of the survey results at some point in the near future.

Appendix A: Email added at registration
How did we determine how many users had not provided an email address at signup to be able to calculate that proportion? This is not trivial, because the MediaWiki database does not store a timestamp of when a user added their email address, nor is there an EventLogging schema in use for logging that kind of information either. The only piece of information in the database that seemed related is the expiration timestamp of the verification token that is emailed to the user when they enter their email address.

We examined the difference between the timestamps of account registration and verification token expiration for accounts registered between January 1 and July 1 2018 on both Wikipedias and found that it is typically set to slightly more than seven days. How much more is "slightly more"? In the vast majority of cases less than ten seconds, which we think is the delay between the system creating the account and the subsequent emailing of the verification token (at which point the expiration timestamp is set to "seven days from now"). We therefore adopted a simple heuristic for determining if the user supplied an email at registration: it happened if the difference between the two timestamps is less than "one week + ten seconds".

Another thing we have to consider is that we do not have information about whether a user supplied an email address at registration but then decided to delete it. This means that they'll show up in our statistic as "did not supply an email at registration". We decided to assert that this is rarely done based on the fact that as of December 19, 64% of Czech registrations and 75% of Korean registrations between January 1 and July 1 did not have a verified email address. This suggested to us that users most likely either supply an email address that they do not check, or do not really care much about email verification, which we took to mean they are also unlikely to delete their email address.

Lastly, the proportion listed in the "added email" section above was not based on an upper limit for how quickly after registration a user can add their email address. This means that users who took the survey shortly after it was deployed have had more time to provide us with an address. In future calculations we will have a limit (e.g. one week), but in the meantime we will assert that if they have not provided us with an address already it's unlikely that they return to do so (in other words, that it's relatively unlikely that a user adds an email address after registration).
