For the purpose of this analysis, we’ve combined the two colorways.\u00a0 The data set, as always, is eBay auctions.\u00a0 In this case, it runs from the Yeezy 2 release in May 2012 through the first week of October 2013.<\/p>\n
Yeezy 2<\/strong> Volume Stats<\/strong><\/span>:<\/p>\nSold Auctions:<\/em><\/p>\n\n- Total Pairs Sold (DS):\u00a0 4,944<\/li>\n
- Total Pairs Sold (Used):\u00a0 797<\/li>\n
- Total Pairs Sold (All):\u00a0 5,791<\/li>\n
- Deadstock Percentage:\u00a0 86%<\/li>\n<\/ul>\n
Unsold Auctions (ended with no sale):<\/em><\/p>\n\n- Total Pairs Unsold (DS):\u00a0 3,284<\/li>\n
- Total Pairs Unsold (Used):\u00a0 794<\/li>\n
- Total Pairs Unsold (All):\u00a0 4,078<\/li>\n
- Sold Percentage:\u00a0 59%<\/li>\n<\/ul>\n
All Auctions (Sold & Unsold)<\/em><\/p>\n\n- Total Pairs on the Market:\u00a0 9,869<\/li>\n<\/ul>\n
Note, unlike just about every other sneaker we have profiled on Campless, we have not listed any price statistics.\u00a0 This is intentional.\u00a0 Price is the big question with Yeezys – because of all sneakers sold on eBay in the past two years, perhaps no sneaker has seen more fakes . . . which makes this the perfect pair for us to explain the various methodologies we use to exclude fakes (and other data outliers) from Campless data, in general.<\/p>\n
What are Data Outliers?<\/strong><\/p>\n“Outliers” are auctions with an extreme sales price (either high or low) which should be excluded from our data analysis\u00a0so that the statistics we publish, like average price, are not artificially impacted.\u00a0 Many outliers on the low side – those priced significantly lower than expected – are fakes.\u00a0 Outliers on the high side – those priced significantly greater than expected – are often auctions with multiple pairs.\u00a0 Of course, extreme prices can also be “junk” auctions – those where the real transaction took place offline or where no sale actually occurred.\u00a0 While only the fake analysis is directly relevant to consumers, it’s important to the accuracy of Campless statistics that both high and low outliers are removed.<\/p>\n
Before we begin the Yeezy 2 analysis, let’s take a look at the summary price statistics if we were to not<\/span> remove outliers.\u00a0 This will provide a nice comparison at the end of our analysis, after fakes, multi-pair auctions and junk are removed.<\/p>\nYeezy 2 Price Stats (without removing outliers):<\/strong><\/p>\nSold Auctions:<\/em><\/p>\n\n- Average DS Price:\u00a0 $1,035<\/li>\n
- High Price (DS):\u00a0 $90,300<\/li>\n
- Low Price (DS):\u00a0 $0.01<\/li>\n
- Average Used Price:\u00a0 $818<\/li>\n
- High Price (Used):\u00a0 $98,900<\/li>\n
- Low Price (Used):\u00a0 $0.99<\/li>\n<\/ul>\n
Unsold Auctions:<\/em><\/p>\n\n- Average DS Price:\u00a0 $1,058<\/li>\n
- High Price (DS):\u00a0 $9,000<\/li>\n
- Low Price (DS):\u00a0 $0.01<\/li>\n
- Average Used Price:\u00a0 $829<\/li>\n
- High Price (Used):\u00a0 $9,999<\/li>\n
- Low Price (Used):\u00a0 $0.01<\/li>\n<\/ul>\n
Take a look at those numbers.\u00a0 Do any<\/em> of them make sense?\u00a0 It takes neither a data scientist nor a sneakerhead to tell you that the auction that ended in a sale price of $98,900 is definitely an outlier – in fact, it was actually a pair autographed by Kanye, which we definitely don’t want skewing our data.\u00a0 Nor does it takes a Campless disciple to figure out that when an auctions “sells” for $0.01, the transaction either took place offline or it was complete junk.<\/p>\nSo it’s clear there are problems with the raw data, but how do we fix it?\u00a0 How do we remove outliers and arrive at a data set that we can use to conduct analysis which will result in accurate statistics and meaningful insights?\u00a0 We’ll dive into that question in Part 2<\/a> . . .<\/p>\n","protected":false},"excerpt":{"rendered":"With the impending (or not) release of the Yeezy 2 Red Octobers, we are reminded simultaneously about all that is good and all that is bad in the realm of collecting sneakers.\u00a0 Nothing is quite as exciting as a release of this magnitude – hype that is typically doled but once a year.\u00a0 On the […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[],"tags":[],"brands":[],"series":[],"verticals":[],"class_list":["post-383","post","type-post","status-publish","format-standard","hentry"],"acf":[],"yoast_head":"\n
