ANOVA stands rau Kev Ntsuam Xyuas ntawm Variance. Hauv SAS Nws yog ua tiav siv PROC ANOVA . Nws ua kev soj ntsuam cov ntaub ntawv los ntawm ntau yam kev sim tsim qauv.
Ntawm no, koj txhais li cas los ntawm Anova?
Analysis ntawm Variance ( ANOVA ) yog ib txoj hauv kev siv los ntsuas qhov sib txawv ntawm ob lossis ntau txoj kev. Tej zaum nws yuav zoo li khib tias cov txheej txheem hu ua "Kev Ntsuam Xyuas ntawm Variance" es tsis yog "Kev Tshawb Fawb Txog Kev Ntsuas." Raws li koj yuav saib, lub npe yog tsim nyog vim inferences txog txhais tau tias yog ua los ntawm kev txheeb xyuas qhov sib txawv.
Koj txhais li cas Anova cov txiaj ntsig? Txhais cov ntsiab lus tseem ceeb rau One-Way ANOVA
- Kauj Ruam 1: Txiav txim siab seb qhov sib txawv ntawm pab pawg txhais tau li cas yog qhov tseem ceeb.
- Kauj Ruam 2: Tshawb xyuas pab pawg txhais tau tias.
- Kauj Ruam 3: Sib piv cov pab pawg txhais tau tias.
- Kauj Ruam 4: Txiav txim siab seb tus qauv haum rau koj cov ntaub ntawv li cas.
- Kauj Ruam 5: Txiav txim siab seb koj tus qauv ua tau raws li qhov kev xav ntawm kev tshuaj ntsuam.
Ib yam li ntawd, qhov txawv ntawm ib txoj kev Anova thiab ob txoj kev Anova yog dab tsi?
A ib - txoj kev ANOVA tsuas yog koom nrog ib factor lossis ywj pheej variable, whereas muaj ob ywj pheej variable hauv ib ob - txoj kev ANOVA . Hauv ib qho - txoj kev ANOVA , cov ib qhov tseem ceeb los yog kev hloov pauv ywj pheej txheeb xyuas muaj peb lossis ntau pawg categorical. A ob - txoj kev ANOVA hloov pauv ntau pawg ntawm ob yam.
PROC GLM yog dab tsi hauv SAS?
GLM Txheej txheem. Cov GLM txheej txheem siv txoj kev tsawg kawg squares kom haum cov qauv linear. Ntawm cov kev txheeb cais muaj nyob rau hauv PROC GLM yog regression, tsom xam ntawm variance, tsom xam ntawm covariance, multivariate tsom xam ntawm variance, thiab ib feem correlation.

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam

Proc CORR hauv SAS yog dab tsi?
Xam thiab luam tawm Cronbach's coefficient alpha. PROC CORR suav cov coefficients sib cais siv cov khoom nyoos thiab cov qauv tsim nyog (scaling the variables to a unit variance of 1). Rau txhua nqe lus VAR sib txawv, PROC CORR suav qhov sib txheeb ntawm qhov sib txawv thiab tag nrho ntawm qhov sib txawv ntxiv
Post hoc xeem hauv Anova yog dab tsi?
Post hoc xeem yog ib feem tseem ceeb ntawm ANOVA. Thaum koj siv ANOVA los ntsuas qhov sib npaug ntawm tsawg kawg peb pab pawg txhais tau tias, cov txiaj ntsig tseem ceeb ntawm cov ntaub ntawv qhia tias tsis yog txhua pab pawg txhais tau tias sib npaug. 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
