The statistical significance of whether the stiffness values of each nucleus (average of the stiffness for this particular nucleus) differed depending on the amount of DNA injected was tested. For comparison, the significance values for the hypothesis of identical distributions for a Student's t-test (lower half of the table) and a one-dimensional ANOVA (upper half) were computed. The differences between all three groups are highly significant.
