Tsib Kauj Ruam Hauv Kev Ntsuas Kev Ntsuas:
- Qhia qhov Null Hypothesis .
- Qhia qhov Alternative Hypothesis .
- Teem Qhov Tseem Ceeb Theem (a)
- Xam cov Kuaj Kev txheeb cais thiab sib thooj P-Tus nqi.
- Kos ib qhov xaus.
Kuj nug, dab tsi yog rau cov kauj ruam ntawm kev ntsuam xyuas kev xav?
- 6 QHOV TSEEM CEEB RAU HYPOTHESIS TESTING.
- HYPOTHESES.
- Kev xav.
- TEST STATISTIC (los yog Confidence Interval Structure)
- REJECTION REGION (los yog Nqe Lus Tshaj Tawm)
- CALCULATIONS (Annotated Spreadsheet)
- Cov lus xaus.
Tsis tas li ntawd, 5 kauj ruam hauv kev ntsuam xyuas kev xav yog dab tsi? Muaj tsib kauj ruam hauv kev ntsuam xyuas hypothesis:
- Ua kev xav.
- Hais txog kev tshawb fawb thiab tsis muaj kev xav thiab xaiv (setting) alpha.
- Xaiv qhov kev faib ua piv txwv thiab qhia qhov ntsuas qhov ntsuas.
- Kev suav cov lej xeem.
- Kev txiav txim siab thiab txhais cov txiaj ntsig.
Tsis tas li ntawd, 4 kauj ruam ntawm kev ntsuam xyuas kev xav yog dab tsi?
1 Qhia qhov plaub theem ntawm kev ntsuam xyuas hypothesis . 2 Txhais null kev xav , lwm txoj kev xav , theem ntawm qhov tseem ceeb, xeem statistic, p tus nqi, thiab statistical tseem ceeb. hom kev ua yuam kev uas cov kws tshawb fawb tswj.
Dab tsi yog hypothesis thiab cov kauj ruam koom nrog hauv kev sim ntawm kev xav?
Muaj 5 lub ntsiab cov kauj ruam hauv kev ntsuam xyuas hypothesis : Qhia koj qhov kev tshawb fawb kev xav as a null (Ho) thiab alternate (Hib) kev xav . Sau cov ntaub ntawv raws li tsim los xeem tus kev xav . Ua ib qho kev txheeb cais tsim nyog xeem . Txiav txim seb qhov null kev xav txhawb los yog tsis lees paub.

Dab tsi yog kauj ruam kawg ntawm xya kauj ruam kev muag tus kheej?
Cov txheej txheem muag tus kheej yog xya kauj ruam mus kom ze: prospecting, pre-mus kom ze, mus kom ze, kev nthuav qhia, rooj sib tham tsis pom zoo, kaw qhov muag, thiab ua raws
Cov kauj ruam hauv peb kauj ruam sau ntawv yog dab tsi?
Hauv cov ntsiab lus dav dav, txheej txheem sau ntawv muaj peb qhov tseem ceeb: sau ua ntej, sau, thiab sau ntawv tom qab. Peb qhov no tuaj yeem muab faib ua 5 kauj ruam ntxiv: (1) Kev Npaj; (2) Kev sib sau ua ke; (3) Composing / Drafting; (4) Kev hloov kho / kho; thiab (5) Pro ofreading
Thawj kauj ruam ntawm 7 kauj ruam txhim kho yog dab tsi?
Xya Kauj Ruam Nruam Txhim Kho Txheej Txheem Kauj Ruam 1: Txheeb xyuas lub tswv yim rau kev txhim kho. Kauj Ruam 2: Txhais qhov yuav ntsuas. Kauj ruam 3: Sau cov ntaub ntawv. Kauj ruam 4: Ua cov ntaub ntawv. Kauj Ruam 5: Txheeb xyuas cov ntaub ntawv thiab cov ntaub ntawv. Kauj Ruam 6: Qhia thiab siv cov ntaub ntawv. Kauj Ruam 7: Siv kev txhim kho
Dab tsi yog 8 kauj ruam ntawm kev ntsuam xyuas kev xav?
Kauj Ruam 1: Qhia qhov Null Hypothesis. Kauj Ruam 2: Qhia qhov kev xaiv lwm yam Hypothesis. Kauj Ruam 3: Teem Qhov Tseem Ceeb Theem (a) Kauj Ruam 4: Xam cov Test Statistic thiab Cuam Tshuam P-Value. Kauj Ruam 5: Kos Cov Lus Qhia
Tus neeg twg tau soj ntsuam kev mloog lus ntawm kev sib raug zoo los ntawm kev ua ib qho kev sim uas yuav tsum muaj cov tub ntxhais kawm cov ntsiab lus los tswj cov kev mob siab rau cov ntsiab lus hauv kev tshuaj xyuas kev kawm?
Milgram Shock Experiment Ib qho ntawm cov kev tshawb fawb nto moo tshaj plaws ntawm kev mloog lus hauv kev puas siab puas ntsws tau ua los ntawm Stanley Milgram, tus kws kho mob hlwb ntawm Yale University. Nws tau ua ib qho kev sim qhia txog qhov tsis sib haum xeeb ntawm kev mloog lus rau txoj cai thiab lub siab ntawm tus kheej
