Learning and Evaluation/Evaluation reports/2015/Other Photo Events/Outputs
We examined how many participants contributed to each program implementation, how many of those participants were new users, existing users, and active users, as well as used this output along with budget to learn examine the dollar cost for each participant.Read this page to learn about the amount of on-wiki content you might expect and costs that have been associated
Participant counts were obtained for 94 of the events (91%).  The number of participants in each contest or event ranged from 1 to 921, with median average of only two participants  Of the total participant base (4,220 users), 2741 (65%) were newly registered (see graph below).
Events with fewer participants tended to have more existing and existing active users, while events with more participants tended to have more new users.
Cost per ParticipantEdit
The photo events captured in this report generated an average of 92 media uploads at costs ranging from $0 up to nearly $900 USD per participant and from $0 to $56 USD per image uploaded with a total of 126,544 media uploaded through the events captured in this report.
With budgets reported for 11 of the events (10%) for which we also had participant data we were able to calculate the cost per participant for each event. Costs ranged widely from large events and small with the most typical cost per participant being zero USD. Still, events cost up to $874.61 per participant in one case, while costs more typically ranged from $2.84 to $28.72 USD. The box and whisker plots illustrate the cost per participant. The chart below shows the cost per participant for two groups: all 18 events and only those four events that reported budgets of more than $0.00 USD.
As the box plots illustrate, typically the photo events had little financial investment, when budgets were reported costs ranged from $1.12 to $874.61 USD per participant and averaged just under $100 USD.
Content Production and Use 
Upload counts were available for 95 photo events (92%). A total of 126,544 images were uploaded to Commons during the 103 events. Of those images, 12,187 (10%) had already been used on Wikimedia project pages by February 2015 when use was assessed. The number of media added per event ranged from 2 to 23,002. The average number of media added per event was 92.
Budget & Content CreatedEdit
The graphic below crosses data about event participation, budget, and number of media uploaded. While programs with more participants and more media uploaded tended to have higher budgets, the 15 events with $0.00 USD budgets offer examples of how small-scale, low-cost programs can be impactful and how they can be applied in different contexts.
Cost per Media UploadedEdit
We calculated the cost per media uploaded for 18 events for which we had budget and media upload data.The graph below compares the cost per media uploaded for the 18 total other photo events and the four events that reported budgets of more than $0.00 USD to the Wiki Loves Monuments events reported this round. Compared to Wiki Loves Monuments, other photo events have a wider spread of costs, with some events being less expensive and others being more expensive.
The highest proportion of unique media used on Wikimedia project pages was 96%
The number of unique media used on Wikimedia article pages ranged from 0 to 1,307. Most often the number of unique media used per event was one, while the median average was 26.representing article use rates ranging from 0% to 96% with an average of 12%. As the graph below illustrates, several events with $0.00 USD budgets uploaded media that were quickly used on Wikimedia article pages. More data may help us determine the trends between these metrics and if the impact continues with scale.
We also looked at how much it costs in terms of media which were used on Wikimedia article pages. The costs reported were typically zero, but from $0 to $114.09, and averaged zero in median and mode.
Hours, Participation, and Media UsedEdit
There are 12 events for which we have number of organizer hours per week (staff + volunteer), number of participants, media uploaded, and unique media used. Organizer hours per week per participant ranged from 0.48 to 31.6 with an average of 7.16.(See the graph below, Organizer hours, media uploaded and unique media used.) Events with more organizer hours per week per participant tended to have more media uploaded and more unique media used per participant. A wider sample of data on organizer hours may reveal more or more nuanced trends between these inputs and outcomes, as well.
Participation and ContentEdit
Events with more participants tended to have more media uploaded and more unique media used on Wikimedia project pages. smaller events with fewer participants and fewer media uploaded have a higher proportion of media used on project pages.
There are very rich data on impactful small programs that we would like to explore more.
Smaller events with fewer participants and fewer media uploaded have a higher proportion of media used on project pages.
This could be due to different approaches, whereby smaller events gathered media specifically to populate articles while larger events focused on content generation irrespective of specific use on Wikimedia article pages.
