'''Q.''' How important is the takeover protection (question S1, choice 1) for a) the survey respondents who are a corporate sponsor of OSM or a commercial company using OSM data (question D1, choices 5, 6, or and b) those respondents who are neither? Is there a difference between the two groups? If yes, is it (statistically) significant?
'''A.''' There is a statistically significant difference between those who answered yes and those who answered no to these two questions. I did not break out the "double no" group ("no" in both categories) because to be frank doing that complicates the problem and the difference in results on initial examination was not that great. You can see the numbers in the spreadsheet [https://wiki.osmfoundation.org/w/images/e/eb/Takeover-rank-company-sponsor.ods here]. Unfortunately, because the raw data must be kept separate, this spreadsheet contains only the values of the calculations and not the formulae, but you can reproduce the calculations from the 28 pivot tables if you wish to check the math. The results were:<br>
sponsor=yes 3.014285714<br>
sponsor=no 4.455867082<br>
company=yes 3.92733564<br>
company=no 4.475280899<br>
In other words, employees of corporate sponsors ranked takeover protection 3rd from the bottom (5th in priority), while non-employees of corporate sponsors ranked it 4th from the bottom (4th in priority). Employees of companies using OSM data ranked takeover protection 4th in priority, while non-employees of such companies ranked it in the same position but more strongly.
The methodology was to assign a rank of 7 to 1 for first choice, second choice, et cetera for the option "Takeover protection". I multiplied the rank of each choice times the number of respondents who made that choice, then took the means and standard deviations (range of course was 1 through 7) and counted the total number of observations. Those data were then fed into the [https://www.medcalc.org/calc/comparison_of_means.php MedCalc comparison of means online calculator] to determine statistical significance.
