Definition
"A hipótese nula" in research refers to the default assumption that there is no effect or relationship between variables. It is tested against data to determine if there is enough evidence to reject it and support an alternative hypothesis.
Etymology
The term "a hipótese nula" comes from Latin and Greek roots. "Hipótese" derives from the Greek 'hypotithenai', meaning 'to suppose or propose,' and "nula" originates from the Latin 'nullus,' meaning 'none' or 'nothing.' Together, they signify the idea of a 'null hypothesis' or a baseline assumption of no effect.
