Polish term or phrase: rozkład t-studenta o n-2 stopniach swobody
Z artykułu o neofobii:
Do analizy współzależności znajomości produktów, chęci ich spożycia oraz motywacji osób biorących udział w badaniu (w próbie) wykorzystano współczynnik korelacji Pearsona. Do sprawdzenia istotności otrzymanych wyników (istotnej różnicy od zera) wykorzystano test wartości korelacji ‪□ w populacji generalnej. Hipoteza zerowa Ho zakłada brak współzależności pomiędzy badanymi cechami w populacji generalnej (Ho: □ =0), natomiast hipoteza alternatywna Ha istnienie takiej zależności (Ha: □ ≠0). Sprawdzianem hipotezy jest rozkład t-Studenta o n-2 stopniach swobody.

In probability and statistics, Student's t-distribution (or simply the t-distribution) is a probability distribution that arises in the problem of estimating the mean of a normally distributed population when the sample size is small. It is the basis of the popular Student's t-tests for the statistical significance of the difference between two sample means, and for confidence intervals for the difference between two population means. The Student's t-distribution is a special case of the generalised hyperbolic distribution.
