Mayelana nalolu hlelo lokusebenza

I-Basics of Statistics ifundisa izibalo eziyisisekelo zabaqalayo, isinyathelo ngesinyathelo: izifundo ezimfushane ezingu-28 ezigabeni ezingu-6, ngemidwebo yokuqala engu-35, izibonelo ezisetshenzisiwe ezingu-43 kanye nemibuzo yokuzijwayeza engu-86.

Qala ngedatha, amagrafu kanye nezibalo ezichazayo (isilinganiso, i-median, imodi, ama-quartiles, ukuphambuka okujwayelekile), bese uthatha izinyathelo zakho zokuqala ku-probability, i-normal curve kanye ne-regression. Isebenza ungaxhunyiwe ku-inthanethi.

Isifundo ngasinye sichaza umqondo ngolimi olulula kuqala, bese sibonisa isithombe kanye nefomula. Igama ngalinye lichazwa lapho livela okokuqala, futhi izibonelo ezisetshenzisiwe zisebenzisa izinombolo ezincane ongazihlola wena.

Ozokufunda

• Idatha kanye nokuSampula: ukuthi izibalo ziyini, abantu kanye namasampula, izinhlobo zedatha, izindlela zokusampula, ukubandlulula ezinhlolovo kanye namasampula, ukuhlolwa kanye nezifundo zokubuka
• Amagrafu eDatha: amathebula emvamisa namashadi ebha, ama-histogram, ama-stem-amaqabunga kanye namachashazi, imvamisa ehlanganisiwe kanye nama-ogives, kanye nesimo sokusabalalisa (okulinganayo, okugobile)
• Isikhungo kanye nokuSampula: i-mean, i-median kanye nemodi; ububanzi, ama-quartiles kanye ne-IQR; amaploti ebhokisi kanye nama-outliers; ukuhlukahluka kanye nokuphambuka okujwayelekile; izikolo zika-z kanye nama-percentile; umthetho we-empirical kanye ne-Chebyshev
• Amathuba: izikhala zesampula nemicimbi, imithetho yamathuba, amathuba anemibandela kanye nokuzimela, i-theorem kaBayes enemidwebo yezihlahla, i-permutations kanye nokuhlanganiswa
• Ukusabalalisa Okuqhubekayo: ama-density curves, ukusatshalaliswa okujwayelekile, okujwayelekile okujwayelekile kanye nethebula le-z, kanye nokusondela okujwayelekile ku-binomial
• Ukuhlangana kanye nokuHlela: ama-scatterplot kanye nokuhlobana, umugqa wezikwele ezincane, ama-residuals kanye ne-r²

Izici
• Izifundo ezingu-28 ezigabeni ezingu-6, kusukela ezincazelweni zokuqala kuya ekusatshalalisweni okujwayelekile kanye nokuHlela
• Imidwebo engu-35 yokuqala: ama-histogram, ama-box plots, ama-ogives, ama-dot plots, ama-tree dagrams, ama-normal curves, ama-scatterplot kanye nemigqa yokuHlela
• Izibonelo ezingu-43 ezisebenzayo ngesinyathelo ngasinye esibonisiwe
• Imibuzo yokuzijwayeza engu-86 enezimpendulo zokuthepha ukuze uveze
• Sesha zonke izifundo esikrinini sasekhaya
• Imodi emnyama
• Isebenza ungaxhunyiwe ku-inthanethi, akukho akhawunti edingekayo
• Itholakala ngezilimi ezingu-8: isiNgisi, isiSpanishi, isiPutukezi, isiFulentshi, isiJalimane, I-العربية, isi-हिन्दी kanye nesi-Bahasa Indonesia

Kungokwabani
• Abaqalayo abafuna izibalo eziyisisekelo zichazwe kalula, ngaphandle kolwazi lwangaphambilini oludingekayo
• Abafundi besikole samabanga aphezulu bahlangabezana nezibalo ezichazayo, amagrafu edatha kanye namathuba okokuqala; kuwusizo lapho kubukezwa izibalo ezichazayo kanye nezingxenye zamathuba e-AP Statistics
• Abafundi basekolishi esifundweni sokuqala sezibalo abafuna isibuyekezo esifushane nesicacile sezisekelo
• Noma ubani ofunda amashadi, isilinganiso kanye nezinhlolovo emsebenzini noma ezindabeni futhi ofuna ukuziqonda

Izisekelo zezibalo ziwusizo lokufunda oluzimele. Okuqukethwe kusekelwe ezincwadini ze-OpenStax Introductory Statistics 2e kanye ne-OpenIntro Statistics (uhlelo lwesi-4) kanye ne-NIST/SEMATECH e-Handbook of Statistical Methods. Ayixhunyanisiwe nanoma yiliphi ibhodi lokuhlolwa, umshicileli wezincwadi, inyuvesi noma inhlangano esemthethweni.
