Document Summary

Alternative hypothesis: a resear(cid:272)her (cid:373)ight e(cid:454)pe(cid:272)t that the e(cid:272)o(cid:374)o(cid:373)i(cid:272) (cid:272)lass a(cid:374)d edu(cid:272)atio(cid:374)al attainment of one"s parents, and the race of the person in question are likely to have an effect on one"s educational attainment. Other types of hypothesis: si(cid:373)ple hypothesis, co(cid:373)ple(cid:454) h(cid:455)pothesis, e(cid:373)piri(cid:272)al h(cid:455)pothesis, logi(cid:272)al h(cid:455)pothesis, statisti(cid:272)al h(cid:455)pothesis. Simple hypothesis: si(cid:373)ple h(cid:455)pothesis is that o(cid:374)e i(cid:374) (cid:449)hi(cid:272)h there e(cid:454)ists relatio(cid:374)ship between two variables one is called independent variable or cause and other is dependent variable or effect. For example: s(cid:373)oki(cid:374)g leads to ca(cid:374)(cid:272)er, the higher ratio of u(cid:374)e(cid:373)plo(cid:455)(cid:373)e(cid:374)t leads to (cid:272)ri(cid:373)es. Complex hypothesis: co(cid:373)ple(cid:454) h(cid:455)pothesis is that o(cid:374)e i(cid:374) (cid:449)hi(cid:272)h as relatio(cid:374)ship a(cid:373)o(cid:374)g (cid:448)aria(cid:271)les e(cid:454)ists. I(cid:374) this type dependent as well as independent variables are more than two. For example: s(cid:373)oki(cid:374)g a(cid:374)d other drugs leads to (cid:272)a(cid:374)(cid:272)er, te(cid:374)sio(cid:374) (cid:272)hest i(cid:374)fe(cid:272)tio(cid:374)s et(cid:272), the higher ratio(cid:374) of u(cid:374)e(cid:373)plo(cid:455)(cid:373)e(cid:374)t po(cid:448)ert(cid:455), illitera(cid:272)(cid:455) leads to (cid:272)ri(cid:373)es like da(cid:272)oit, Empirical hypothesis: worki(cid:374)g h(cid:455)pothesis is that o(cid:374)e (cid:449)hi(cid:272)h is applied to a field.
