The current statistics are: total revenue: $301,252.18
number of purchases: 43,819
average purchase: $6.87
average windows: $5.72
average mac: $7.72
average linux: $13.72
Based on their "total revenue by platform" chart, I estimate the per-platform revenues to be: windows: ~54% , or ~$162,676.18
mac: ~23% , or ~$69,288
linux: ~23% , or ~$69,288
An approximate Linux revenue of ~$69,288 and average purchase of $13.72 gives us ~5050 total Linux purchases.Now, it's true that a very large contribution could influence the mean. However, they also include a list of the top 10 contributions: top 10 contributions:
$1,000
$700
$666
$650
$600
$500
$500
$337.42
$313.37
$300
We can assume that every one of these was designated a Linux purchase, treat them as outliers, and remove them from the statistics. The adjusted statistics are: outlier revenue: $5,566.79
adjusted total revenue: $295,685.39
adjusted linux revenue: ~$63,721.21
adjusted linux average: $12.61
So even removing the top 10, Linux users are still significantly more generous (on average) than users of the other two major platforms.You could argue that a sufficient number of Linux users donating in the $100-$300 range could skew the results, but I believe such a high number of extremely generous users would prove my point anyway. |
