Art of Stat: Inference

I-Art of Stat: Uhlelo lokusebenza lwe-Inference lunikeza ukufinyelela kumamojula alandelayo:

- I-Inference for Proportions (isampula eyodwa nezimbili ezizimele)
- Inference for Means (isampula eyodwa nambili ezimele)
- I-Inference ku-Linear Regression Models (umthambeka, ukuzethemba nezikhawu zokubikezela)
- Ukuhlolwa kwe-Chi-square (Ukuzimela/I-Homogeneity kanye Nobuhle Bokufaneleka)
- I-ANOVA yendlela eyodwa yokuqhathanisa izindlela ezimbalwa

Azikho Izikhangiso. Akukho Okubhaliselwe. Vula wonke amamojula ngemali encane yesikhathi esisodwa, noma ngalinye ngenkokhelo encane nakakhulu.

Ukufaka idatha yakho kulula:
Uma unokuqaphela okumbalwa (noma unezibalo ezifingqiwe), mane uzibhale. Ukuze uthole amasethi edatha amakhulu, layisha ifayela le-CSV ledatha yakho eluhlaza ku-akhawunti yefu (efana ne-iCloud noma i-Google Drive) noma vele uthumele i-imeyili ifayela kuwe. Bese, vula ifayela le-CSV kuhlelo lokusebenza bese ukhetha okuhlukile kokuhlaziya kwakho. Ungakwazi futhi ukumane ukopishe futhi unamathisele idatha eluhlaza evela kuhlelo lokusebenza lwesipredishithi (Njengezinombolo ku-iOS noma ku-Google amashidi). Amasethi edatha ayisampula anikeziwe.

Imiphumela iyamangalisa:
Uhlelo lokusebenza luhlinzeka ngeziqephu ezifanele (eceleni necele noma amabha amashadi astakiwe, ama-boxplots, ama-histogram) futhi lihlanganisa futhi libone ngeso lengqondo izikhawu zokuzethemba kanye namavelu we-P wokuhlola imibono eqanjiwe. Lonke ulwazi olubalulekile (njengamaphutha ajwayelekile, umkhawulo wamaphutha, izikolo z noma t namadigri enkululeko) aboniswa ngokucacile futhi alebulwe. Inani le-P liboniswa kugrafu ngokusatshalaliswa okuvamile, t-, noma kwe-Chi-Squared.

Ithuthukiselwe kokubili abafundi nothisha njengethuluzi eliwusizo lokuqhuba inkomba yezibalo eyisisekelo futhi ibone ngeso lengqondo imiphumela uma uhamba.

Uhlelo lokusebenza lusebenza kumodi yokungaxhunyiwe ku-inthanethi neyokungaxhunyiwe ku-inthanethi (uhlelo lokusebenza lubonisa ukuthi lukumodi engaxhunyiwe ku-inthanethi ngesibhengezo esikhulu esiluhlaza), okulenza lilungele izivivinyo.

Uhlelo lokusebenza futhi lunamamojula anikelwe wokuhlola imiqondo efana namathuba okufakwa kwezikhawu zokuzethemba noma imiqondo yamaphutha ohlobo I & II namandla. Empeleni ingathola iphutha loHlobo lwe-II namandla okuhlolwa kwezilinganiso (kanye nokuhlola okuthile kwezindlela.)

Yabelana kalula ngemiphumela yakho ngokuthatha izithombe-skrini.
