alternative hypothesis

alternative hypothesis
Danh từ
Số nhiều: alternative hypotheses

This term is a technical expression used exclusively within the framework of null hypothesis significance testing (NHST). It represents the researcher's actual prediction or the claim that a specific effect, difference, or relationship exists within a population. It stands in direct opposition to the null hypothesis, which assumes no effect.

In a practical research setting, the alternative hypothesis is not proven true in a definitive sense; rather, it is supported when the evidence is strong enough to make the null hypothesis statistically improbable. It is typically denoted by the symbol H1 or Ha in academic papers and statistical reports.
