Raw data subjected to statistical analyses are summarized in Table 2 which shows the numbers of chalkbrood mummies found in comb cells and collected from dead bee traps, landing boards, and bottom boards. Possible misclassification of colonies HP-2 and CG-19 added to the variation between colonies within the treatment groups and affected statistical significance of the data. Data from each of the 5 calculations of efficiency ratios were subjected to statistical analyses. The results were in general agreement. However, the estimates of experimental variation were quite different. Calculation 1 (daily calculation) had 5-20 times the amount of variation of the weekly estimates. Calculations 2 and 4, which were weekly estimates involving only 2 days of observing mummies in comb cells, were approximately 3 times more variable than calculations 3 and 5, which had 3 estimates of comb cell counts.
