Abstract

1Alături de cvasi experimente, studiile
corelaţionale reprezintă poate cele mai
frecvente tipuri de studii utilizate în cercetarea
aplicată. În condiţii obişnuite un astfel de
studiu presupune colectarea simultană a mai
multor date (ex. indici de stres, vechime la
locul de muncă, anxietate, venit, număr de
absenţe, etc) şi calcularea coeficienţilor de
corelaţie pentru a surprinde existenţa unor
eventuale asocieri a două sau mai multor
variabile măsurate (Cohen, 2001). Aceste
demers pare a fi unul simplu şi de obicei nici
nu ridică probleme pentru cercetători. În
cercetările publicate, de obicei, sunt
comunicate: procedura de colectare a datelor
(mai rar şi indicii de consistenţă internă deşi
aceasta afectează valoarea coeficienţilor de
corelaţie, implicit concluziile studiului),
valoarea coeficienţilor de corelaţie precum şi
probabilităţile calculate în baza ipotezei nule
(Ho:ρ=0) a coeficienţilor r.
