Table 3. Estimated variances of arithmetic mean and median methodsa.

a

Variances were calculated in the condition where 20 mosquitoes from a single COM were dissected.

b

Concentration of 4B7 mAb in a feeder [µg/ml].

c

Variance of PIm when calculated using arithmetic mean.

d

Variance of PIm when calculated using median. The value “n missing” is the number out of 100,000 simulations with median = 0 in the control so that percent inhibition of a test could not be calculated.

e

Average of variance (SMFA using mean)/variance (SMFA using median) from 100,000 simulations. This many simulations ensures that we have 95% confidence that the estimates of the expected variance ratios are within 0.04 of their true values.
