Senator Back's use of stats!
So....Hansard for September 2013 has our veterinarian senator telling parliament:
"For the period of July to December 2013, our livestock exporters exported 441,644 cattle. Of that number, only 535—0.12 per cent—were lost during the voyage.Let me put it into perspective. I gave you the figures of 0.12 per cent for cattle and 0.15 per cent... the mortality levels of the cattle on the range lands—excluding drought and overstocking, which was caused by the disastrous decision of the then Labor government to ban the export of live cattle to Indonesia—were about three to eight per cent per annum. Compare that with 0.12 per cent... The mortality rate for human beings in this country is 0.6 per cent, some four times the mortality rate of cattle on ships going to our destination ports..".
With respect Senator, you cant statistically compare 0.12% mortality on variable length voyages (mostly 5-10 days) with an annual 3-8% (or 0.6%) mortality, that is over 365 days. Cant be done.. statistically and scientifically INVALID!
