significance level; critical p-value
Technical term in statistics; the threshold probability below which a null hypothesis is rejected. Commonly set at 0.05 or 0.01.
In this study, the significance level was set at 5%.
If the p-value is smaller than the significance level, we reject the null hypothesis.
p値 is the calculated probability, while 有意水準 is the predetermined threshold for significance.
帰無仮説 is the null hypothesis being tested; 有意水準 is the criterion for rejecting it.
Compound of 有意 (significant) and 水準 (level), a direct translation of the English statistical term 'significance level'.
