The 19th annual KDnuggets Software Poll had over 2,300 voters, somewhat less than in 2017, perhaps because only one vendor – RapidMiner – had a very active campaign to vote in KDnuggets poll. On average, a participant selected about 7 different tools used, so votes with just one tool selected stood out. We removed about 260 such “lone” votes (which mainly were from RapidMiner), because even if they represented legitimate users of that tool, their experience was very atypical and would skew the results. To compare “apples” to “apples” I also removed such lone votes from 2016 and 2017 data (about 11% in 2017 and 12% in 2016), so the 2017 numbers for most tools will be slightly different than what was reported then.
