  1. The numbers in bold represent the tests are the most efficient and do not differ statistically from one another. The P-value is from the results of the Friedman ANOVA. The order of the rating of test is based on the mean rank calculated by the Duncan’s multiple range test; the most efficient test (i.e. the test with the smallest mean rank) is rated the best with a score of 1 and the least efficient with a score of 15
