Table 6 shows the variability in percentage of fat for the semiofficial test. The mean, or average percentage of fat, for the semiofficial period is 3. 43 . 006 percent. It is true that this average test is based on a rather selected group of cows; but the probable error ( . 006) indicates that this group of 1, 295 is adequate to determine a reliable average percentage of fat for the class of cows making semiofficial tests. The standard deviation of .
