I have received a few queries on some statistical discrepancies between my report and the commentary by Hans Vredevoort.  Kwik Surveys incorrectly (in my opinion) calculates percentages for any multiple choice questions.  <\/p>\n

For example, question 46.  Hans chose to share the results of all 614 people that answered questions (including 14 who didn\u2019t use Hyper-V at work and 192 that existed the survey half way through), preferring to analyse individual questions based on as many people as possible.  Approximately 440 people would probably have answered this question, and 309 stated that they use VMM.  The Kwik Surveys report showed the percentage as 29.4%, not the approximate 70% that 309 of 440 actually is.  What Kwik Surveys did was total up all selected answers, 1051 (because around 600 people selected multiple answers, as we requested), and said that 309 of 1051 was 29.4%.  Kwik Surveys calculated percentage badly under represents what percentage of the sample actually use VMM.<\/p>\n

So that\u2019s why I spent a good bit of time creating a spread sheet (in my raw data download<\/a>) that takes the number of answer selections and divides them by the number of respondents to get a percentage.  In my case, I only used the answers from those respondents that answered all questions \u2013 this allows me to combine and use answers from different questions to draw conclusions.  I also excluded those who don\u2019t use Hyper-V at work \u2013 I was interested in cloud and Systems Management topics which would have been irrelevant to them.  In the case of question 46, 282 of 408 respondents said that they used VMM.  That\u2019s 69.12% of the sample.<\/p>\n\n\n\n\n\n\n\n\n\n\n

To be fair, I don\u2019t have a life, and I spent a lot of time in the two nights after closing the survey, taking the numbers and calculating the accurate percentages.  Hans, who does have a life, trusted the Kwik Survey report.  And this is our first time doing this.  We\u2019re not professional pollsters.  But we\u2019re learning \u2026 and we will get it right for The Great Big Hyper-V Survey of 2012<\/a>.<\/p>\n

My 69.12% report is an accurate reflection of VMM usage, as opposed to the very misleading 29.4% that Kwik Surveys has calculated.<\/p>\n
