Sampling

Results are supposed to be reported out of Sample populations. Non responces and outliers shuould always fall below the thresh hold cut off. In the IW poll that thresh hold is 5.8%, anything with a score below 5.8% is not statistically valid and any result that is within 5.8% of any other are statistically tied. That is why NT Workstation and IOMega Jazz Drive are reported as bing tied in the client category.
Of course IW forgot to report the three other ties and reported 7 items that were under the statistical cut off. The fact that what should have been a statistical ourlier, other, shows up in the overall category brings the results of that category into question.
