\@alexanderwinterstetter Data looks interesting, might be possible to find out if some referees are biased. I’d like to know more about the data before I can start any analysis, which, as we can’t look into the source in this case, you’d have to provide. Especially the last few columns (“Alpha_3","meanIAT","nIAT","seIAT","meanExp","nExp","seExp") are not labelled enough for someone with only little knowledge of soccer to understand. Data Cleaning:

• First task seems easy, I’d like to see the usage of this variable later one.
• Interesting, but I don’t see how to do this given this data set. Data Manipulation:
• I like the general question, which leaves room for different answers
• Pretty much impossible, as a row doesn’t contain one game. (And what about players that got in during the game?)
• Maybe a group by function to only include some countries, some players with a min. amount of games would be a good alternative task.
• You could also include a task where the table is split up into an aggregated table of players, one of referees, and one of games. Data Visualization:
• Seems like a good amount of pretty doable tasks Final Thoughs: Your dataset is also about referees, but they don’t appear in the tasks at all. You could probably plot referees vs clubs/players from a specific country (for one or all leagues) and use yellow/red cards for an intuitive kind of heatmap!

@alexanderwinterstetter Hey, if possible I'd like to know in which year the data was collected, to have a better approach for the ages of the players than to use today()-birthday.

Hi Daniela,

I think Alex put the end of the studies year as a reference to compute the age of the players (if I recall correctly).

Best, Martin

Thank you for the prompt reply, @martin-raden, I didn't find this in the dataset or project description. I think he mentioned it in the short presentation, but I don't recall the year anymore. It's not too important, but today() a lot of the players seem somewhat too old for league play.

Hello, you can use as a reference the day "31.12.2012"

Sorry for the late reply!

@alexanderwinterstetter , I've uploaded the pull request, you'll find my solution as Soccer_project.Rmd in there.
