Document Summary

Method of determining internal consistency of responses. This is i(cid:374)t(cid:396)a(cid:272)lass (cid:396)elia(cid:271)ilit(cid:455) (cid:894)does(cid:374)"t dete(cid:396)(cid:373)i(cid:374)e sta(cid:271)ilit(cid:455)(cid:895) This alpha is high if ppl tend to answer all questions near the same end of the scale (e. g. a(cid:374)s(cid:449)e(cid:396)i(cid:374)g (cid:862)so(cid:373)eti(cid:373)es(cid:863) fo(cid:396) (cid:373)ost (cid:395)uestio(cid:374)s(cid:895) Alpha coefficient is calculated by using analysis of variance. O(cid:374)l(cid:455) o(cid:374)e sou(cid:396)(cid:272)e of e(cid:396)(cid:396)o(cid:396) is e(cid:454)a(cid:373)i(cid:374)ed a(cid:374)d that"s the diffe(cid:396)e(cid:374)(cid:272)es i(cid:374) test ad(cid:373)i(cid:374)ist(cid:396)ato(cid:396)s. Objectivity coefficients range between 0. 0 and 0. 1. E. g. i(cid:373)agi(cid:374)e the(cid:396)e"s a test (cid:271)ei(cid:374)g ad(cid:373)i(cid:374)iste(cid:396)ed (cid:271)(cid:455) t(cid:449)o diffe(cid:396)e(cid:374)t (cid:396)esea(cid:396)(cid:272)he(cid:396)s to the sa(cid:373)e g(cid:396)oup of subject, same test, everything the same and everything carefully controlled. The only reason for differences to exist would be the fact that there are 2 different people administering the test. Compare the two sets to measure the objectivity of the test. Tests for things that are easy to measure are reasonably high in objectivity versus a more subjective test such as for motivation, etc. (something not easily measured)
