One-way analysis of variance

Male: F = 0.915, p > 0.05; female F = 1.641, p > 0.05

Male: F = 0.552, p > 0.05; female F = 1.899, p > 0.05

  1. Using one-way analysis of variance, the difference of lateral ventricle volume between male and female infant was of no statistical significance (male: F = 0.915, p > 0.05; female: F = 1.641, p > 0.05), considering that the number of infants with age lower than 3 months was only 12, which was too less. Removing such group, the differences among the other three groups were still of no statistical significance (male: F = .552, p > 0.05; female: F = 1.899, p > 0.05)
