When such statistical analysis has been done regarding bodyfat calipers or weightloss bioelectric impedance or the other (inexpensive) alternatives, the probable error has nearly always been greater than 10%. Very few actual scientific studies have been done regarding such products, but some have even sugggested that +/-15% is not unusual. This implies that if ONE measurement was done, the value obtained IS LIKELY TO weightloss BE off (in either direction) by that large value. With such terrible accuracy, getting a reading of 19% (a weightloss nice result!) could actually mean 34% (seriously obese) or 4% (professional athlete). |

| Under national institutes of health some conditions, hydrostatic weighing has given inaccurate results, and a discussion below explains why that national institutes of health was possible and how to avoid such errors. A comment should be made about "precision" or "accuracy" as every national institutes of health product is presented as having unbelievably good performance! The correct attitude is to have a scientific approach, which is based on the repeatability of results. This cannot be known from a single measurement, or even a small number of measurements. But if the measured results of ten or twenty or fifty (blind) tests (on the same person, near the same time) are analyzed statistically, a "probable error" value is obtained. For the hydrostatic weighing method, that Probable Error is generally much less than 1%. |
