These are called "non-detects" and make it impossible to compute the sample mean concentration. When zero is substituted for each non-detect, the standard may not exceed. But when substituted with a value equal to the detection/reporting limit, the standard may exceed. Which is correct? Has...
The mean is one of three ways to measure central tendency in statistics. The mean refers to the numerical average of a set of numbers. Two other measures of central tendency are the median, which refers to the number that is in the middle of an ordered set of numbers, and the mode, w...
The mean, median and mode are measures of central tendency and may also be referred to collectively as types of averages. The term “mean” in the context of statistics refers specifically to the arithmetic mean since there are other types of means, such
When you perform an experiment that gives a series of observed values which you want to compare against theoretical values, the root-mean-square deviation (RMSD) or root-mean-square error (RMSE) lets you quantify this comparison. You calculate RMSD by finding the square root of the me...

were actually 19.45 potato chips (that’s the mean value) in each of the 11 bags, we’d have a combined total of 214 chips—just as we did before. Technically, that’s exactly what the mean value means—nothing more, nothing less. It’s certainly a reasonable way to calculate a ...
