The GEOMEAN function calculates the geometric mean of a set of numbers by returning the nth root of n numbers. Looking for abbreviations of GMFR. Identify the value that occurs most often.
On SPSS you can get the arithmetic mean.
A geometric mean titer of the indicator virus is determined by at least 3 weekly titrations in embryos. An average calculated by adding the value of the points in a data set and dividing the sum by the number of data points. Utilizing this mean titer the indicator virus is diluted so that 1 mL of diluted virus contains 1000 to 3000 TCID 50 This will provide 100 to 300 TCID. However instead of adding the numbers together and dividing by the number ofvalues you multiply the numbers together and take the root of the number of them together.
