INGXENYE 7: Istatistiki nokusabalalisa

Ingxenye 7: istatistiki nokusabalalisa. Uzothayipha idatha kuthebula, ufunde isilinganiso, ukuchezuka okujwayelekile nama-quartile, ulinganise umugqa noma ijika, bese usebenzisa ukusabalalisa okujwayelekile, okwe-binomial nokwe-Poisson.

Istatistiki: idatha

Isibonelo 27: istatistiki, idatha. MODE, 1 iyimodi ye-STAT. Khetha olunye lwezinhlobo eziyisishiyagalombili zestatistiki, bese uthayipha idatha kuthebula.

? MODE 1, bese kufakwa inombolo
? Ukuthayipha idatha 20, 30, 40, 40, 50
? Ukulungisa idatha
? Ithebula ledatha

Istatistiki: imiphumela

Isibonelo 28: istatistiki, imiphumela. Vala ithebula nge-DATA. ALPHA kanye 8 bese kuvula imenyu ye-STAT nemiphumela.

? Idatha: 95, 80, 80, 75, 75, 75, 50
? Amanani estatistiki
? Amanani estatistiki, kuyaqhubeka
? Idatha emugqeni
? Imenyu ye-STAT
? Inani lestatistiki esibalweni
? Irigreshini eqondile: amapheya ka-x no-y
? Umugqa y = a + bx
? Iziqagelo ezivela emugqeni
? Irigreshini yekhwadrathikhi: amaphoyinti amahlanu
? Ijika y = a + bx + cx²
? Iziqagelo ezivela ejikeni
? Amafomula

Amathuba ajwayelekile

Isibonelo 30: amathuba okusabalalisa okujwayelekile. Kumodi ye-STAT, imenyu ye-MATH inemisebenzi P, Q no-R yokusabalalisa okujwayelekile okulinganiselwe, kanye nomsebenzi olinganisa inani.

? P, Q, R no-→t
? Amamaki okuhlolwa angama-50
? Isilinganiso, ukuchezuka okujwayelekile, amathuba

IMODI 7 – Ukusabalalisa

Imodi ye-DISTRIBUTION: MODE, 7. Ibala ngezinsabalalisa ezijwayelekile, i-binomial ne-Poisson, futhi impendulo igcinwa enkumbulweni ANS.

? Imisebenzi eyisikhombisa
? Ukusabalalisa okujwayelekile: isilinganiso esingu-60, ukuchezuka okujwayelekile okungu-6
? Ukusabalalisa kwe-binomial: imizamo engu-15, impumelelo engamaphesenti angu-30
? ZAMA WENA
? Ukusabalalisa kwe-Poisson: isilinganiso esingu-3.6
