Document Summary
If our p value is greater than . 05, it is still possible that the iv did have an effect on the. Dv but for this particular sample the results were not evident: (cid:862)i failed to reje(cid:272)t the (cid:374)ull(cid:863) (cid:862)i (cid:272)a(cid:374) (cid:374)ot rule out the possi(cid:271)ilit(cid:455) that there is a(cid:374) effe(cid:272)t(cid:863) The file-drawer effect: researchers/journals typically only publish results that show statistical significance. 10% more weight: a(cid:374)d had (cid:271)etter (cid:272)holesterol a(cid:374)d higher s(cid:272)ores o(cid:374) a (cid:373)easure of (cid:449)ell (cid:271)ei(cid:374)g, how, the researchers measured 18 different variables: well-being, total cholesterol, sleep quality, sodium levels, blood protein, bmi, triglycerides. If you get a result showing that neutral is faster in your experiment, that is good . If someone else did the same experiment again and got a similar result (neutral if faster(cid:895), that is (cid:271)etter . If several other people all did the same experiment and kept finding that neutral was faster, that would be even more convincing.
