Statistic - To view a particular statistic for analytes in a batch, select one of the following:

• Median - The point in a data set where there are as many values occurring above it as

there are below it.

• Test Result - The calculated analysis value for quantitative or qualitative assays derived

from standards with known values.

• Range - A semi-quantitative result for a particular numerical result falling between a

predefined set of values such as “Normal” or “Negative”.

• Count - Gated events.

• Net MFI (Median Background) - Net MFI median background.

• Mean - Average of all values in a set of results.

• % CV of microspheres - The measure of relative dispersion within the distribution.

%CV = 100 x Std Dev / Mean

• Standard Deviation - For calculating sample variability or dispersion, Luminex uses the

standard deviation formula.

• Peak - The value that is equal to the largest number of data points within the distribution.

For example, in data set {1,2,2,3,3,3,4,5}, 3 is the peak because it occurs the largest

number of times in the distribution list.

• Trimmed Count - The number of data points in the trimmed distribution (Nt).

• Trimmed Mean - The sum of the data points in the trimmed distribution divided by the

number of data points.

Trimmed Mean = Σxi / Nt
