Statistical analysis of force values averaged across all test points for each fixation technique at 2 cm measured displacement. Confidence intervals were calculated using the Satterthwaite’s approximation (Welch’s t-test) due to likelihood of unequal variance. Difference values are the result of subtracting the mean value for the method in the row from the mean value for the method in the column (column mean-row mean). Differences showing statistical significance (p < 0.05) are listed in bold.
