Txawm li cas los xij, ANOVA Cov txiaj ntsig tsis txheeb xyuas qhov sib txawv tshwj xeeb ntawm cov khub txhais tau tias tseem ceeb.
Tsis tas li ntawd, kev txheeb xyuas tom qab hoc siv rau dab tsi?
Tshaj tawm - Kev Xeem . Tshaj tawm - hoc (Latin, lub ntsiab lus " tom qab qhov no") txhais tau tias los txheeb xyuas cov txiaj ntsig ntawm koj cov ntaub ntawv sim. Lawv feem ntau ua raws li kev ua yuam kev hauv tsev neeg; qhov tshwm sim tsawg kawg yog ib qho yuam kev Hom I hauv ib pawg (tsev neeg) ntawm kev sib piv.
Ib tug kuj nug, thaum twg kuv yuav tsum siv Howell post hoc test? Ua Ua si - Howell xeem , uas yog siv los sib piv txhua qhov ua tau ua ke ntawm pab pawg sib txawv thaum qhov kev xav ntawm homogeneity ntawm kev sib txawv raug ua txhaum. Qhov no pos hoc test muab kev ntseeg siab rau qhov sib txawv ntawm pab pawg txhais tau tias thiab qhia seb qhov sib txawv yog qhov tseem ceeb.
Ua li no, Tukey post hoc test qhia dab tsi?
Cov Tukey Test (los yog Tukey txheej txheem), kuj hu ua Tukey's Kev ncaj ncees Qhov txawv xeem , yog a ncej - hoc tes raws li qhov kev faib tawm ntawm cov tub ntxhais kawm. Ib ANOVA xeem tuaj yeem qhia rau koj yog tias koj cov txiaj ntsig tseem ceeb tag nrho, tab sis nws yuav tsis qhia koj raws nraim qhov sib txawv ntawd dag.
Cov piv txwv post hoc yog dab tsi?
Post hoc yog ib qho kev poob siab uas ib qho laj thawj uas txij li qhov xwm txheej tshwm sim ua ntej lwm tus, ces thawj qhov xwm txheej tshwm sim rau lwm tus. Piv txwv ntawm Post Hoc : 1. Peb pawg ncaws pob tau poob mus txog thaum kuv yuav khau tshiab. Peb tsis tau poob ib qho kev ua si txij li thaum kuv tau txais kuv nkawm khau muaj hmoo!

Cov Txheej Txheem Sib Sau ntawm Alleles hauv Cov Pej Xeem yog Nws Gene Pas. Population geneticists kawm txog qhov sib txawv uas ib txwm tshwm sim ntawm cov noob hauv cov pejxeem. Kev sau ntawm tag nrho cov noob thiab ntau hom kev hloov pauv lossis allelic ntawm cov noob hauv cov pejxeem yog hu ua nws cov gene pool
Dab tsi yog cov pej xeem ntawm cheeb tsam sab hauv plains?
Qhov ntxiv North koj tshawb txog Sab Hauv Plains, qhov txias dua nws yuav dhau los. Qhov no piav qhia vim li cas cov pej xeem ntawm North West Territories tsuas yog kwv yees li 44,340 tus neeg.

Lub hom phiaj ntawm cov tshuaj biotin-histidine hauv Ames kuaj yog dab tsi? Cov biotin ua haujlwm ua cov kab mob loj hlob stimulator. Cov tshuaj histidine yog siv los tso cai rau cov kab mob loj hlob tuaj, yog li tso cai rau cov cell mus rau kev faib cov cell, uas tsim nyog rau kev hloov pauv
Post hoc pairwise kev sib piv yog dab tsi?
Ib Txoj Kev ANOVA Post Hoc Tests.
