| Mar 25, 2015 at 18:26 | comment | added | Nick Cox | The extra information (added after I wrote and posted my answer) that 59.4% were below 0.005 mg/kg implies that the reported summary statistics are not even consistent. Note that p5 is already reported as 0.006 mg/kg. You cannot have the 5% point at 0.006 and the 59.4% point at 0.005. Note the median must also be $\le$ the 59.4% point. If this is someone's typo, then OK, but what else is wrong? | |

When you add details, please also put them into the question itself, so that later readers don't have to hunt through comment threads to find important information. | |

| Mar 25, 2015 at 15:28 | comment | added | whuber♦ | What was the count of the data? That would be very useful for incorporating the max in the estimation as well as for assessing the uncertainties in these statistics. | |
