What do the statistical terms mean?

 

Average Average sensor glucose reading. 
Minimum The lowest sensor glucose reading. 
Quartile 25 This is the sensor glucose reading whereby 25% of all readings fell at or below this value, after ranking all values from lowest to highest. 
Median The midpoint of all the sensor glucose readings, where half the readings fall below this value and half the readings fall above.
Quartile 75 This is the sensor glucose reading whereby 75% of all readings fell at or below this value, after ranking all values from lowest to highest.
Maximum The highest glucose reading.
Standard Deviation (SD) A measure of variability in sensor glucose readings around the Average. The larger the Standard Deviation, the larger the variability.
Estimated Standard Deviation (Est. SD) A separate (SD) statistic that first removes the top 25% and bottom 25% of sensor glucose readings (considered “outliers”) before calculating the standard deviation.                          
Inter Quartile Range (IQR) The difference between the Quartile 75 reading and the Quartile 25 reading (Quartile 75 – Quartile 25).
Standard Error of the Mean (SE Mean) Another estimate of variability that is calculated by dividing the SD by the square root of the # of values.
Percentage Coefficient of Variation (% CV) Another estimate of variability that is calculated by dividing the SD by the Average.
