For example, a recent research on online self-reported height against objectively measured data in young Australian adults revealed that self-reported height is significantly overestimated by a mean of 1.79 cm for males and 1.29 cm for females .

After correcting these, we find that real height differences \(10-(4.08-1.11) = 7.03\text< cm>\) for men, and \(12-(4.08-1.11) = 9.03\text< cm>\) for women would be significant.
