The use of numbers to determine policy is fraught with complication. Here is a simple rule that governs all use of statistics in the science world.
Most research is done to use a sampling that is then used as the basis for generalizing to the whole. That automatically involves error. So there must be measures taken to insure that the sample best represents the entire population that is being studied.
We have all read the political polls, which must identify the scope of the sample (likely voters, registered voters, random people, members of a particular party, etc.). We then read a final line that the numbers are within several points of accuracy. This site is not the place for a statistics lesson. But this is enough to point to the matter of inference from a sample to a whole. One can trash the meaning of results by noting the poor sampling used. And that is much the issue here.
The media are culprits of using a single individual as representative of a whole, something no statistician would ever accept.
I consider Cuomo an enemy of the Jews, and same goes for the mayor. I wish them the worst, and daven for that daily. But I do not believe in these protests, not because of the position, but the yelling there has no effect. I want to see these evil politicians ousted at the ballot box.
