Hypothesis
Does the season of birth affect handedness in young people?
Conclusion
The study found no evidence that season of birth influences handedness in humans.
Supporting Evidence

- There was no difference in the seasonal distribution of birth between right-handed and non-right-handed groups.
Takeaway
The study looked at whether being born in a certain season affects if someone is right or left-handed, and it found that it doesn't.
Methodology
The study used a random sample of high school students and assessed handedness using the Edinburgh Handedness Inventory.
Limitations
The study only included students born in a single year and may not represent broader populations.
Participant Demographics
The sample comprised 457 males and 520 females, all high school students from Belgrade, Serbia.
