Use the following formula to calculate the CVR: In Unity Real Time ™ online, the CVR appears on the Data Analysis Grid and … Parameters : arr : [array_like] input array. In reality, the mean can … For instance, the standard deviation (SD) is 17% of the mean, is a CV. I'm a biochemist and I usually compare the variability of my measurements in terms of coefficient of variation (CV) since I can "visualize" the deviations more easily in terms of percentages deviation from my mean value. Enter the data to be analyzed in one column of an Excel spreadsheet. Now, I measured an analyte 20 times in a sample in one month, and again 20 times the second month.
