Qhov ntau yog qhov kev ncua deb ntawm tus nqi siab tshaj mus rau tus nqi qis tshaj. Qhov Inter-Quartile Range yog qhov tseeb qhov ntau ntawm cov quartiles: qhov kev ncua deb ntawm qhov loj tshaj plaws quartile mus rau qhov tsawg tshaj plaws quartile, uas yog IQR=Q3-Q1.
Dab tsi yog qhov txawv ntawm qhov ntau thiab qhov sib txawv?
Thaum qhov ntau muab rau koj sib kis ntawm tag nrho cov ntaub ntawv teev, qhov kev sib cuam tshuam muab rau koj kev sib kis ntawm nruab nrab ib nrab ntawm cov ntaub ntawv teev.
Puas yog IQR ib tus lej lossis ntau yam?
Interquartile ntau yam yog qhov sib txawv, yog li qhov sib txawv ntawm peb thiab thawj quartiles IQR=Q3 - Q1. Yog li nws yog tus lej ib tus lej yog li qhov no yog qhov koj qhia nws.
Puas IQR ib txwm me dua li qhov ntau?
Interquartile ntau ib txwm me dua li qhov. Qhov tsib-ntu cov ntsiab lus ntawm cov qhab nia xeem hauv chav qhia kev txheeb cais yog: Min=23% Q1=71% Median=83%, Q3=86% thiab Max=100%.
Puas IQR ib txwm 50%?
Cov kev sib cuam tshuam suav nrog 50% ntawm cov ntaub ntawv hauv nruab nrab. Cov ntsiab lus qis thiab sab saud ntawm qhov nruab nrab 50% cheeb tsam no yog quartile 1 thiab quartile 3, feem.

Puas muaj ntau yam thiab ntau yam zoo ib yam?
Kev sib sib zog nqus-qhov sib txawv ntawm qhov nqaim-ntawm cov khoom lag luam txhais tau hais tias tus neeg muag khoom nqa ntau qhov sib txawv ntawm ib yam khoom. Ntau yam-qhov sib txawv ntawm qhov nqaim-ntawm cov khoom txhais tau tias tus neeg muag khoom nqa ntau yam khoom sib txawv.
Puas yog cov hniav ntau ntau yam caj ces?
Kev muaj ntau cov hniav uas xav tias muaj cov caj ces. Peb tshaj tawm cov ntaub ntawv tsis tshua muaj qhov pom ntau cov hniav uas tsis muaj lwm yam mob hauv 3 tiam; txiv, tub, thiab ob tug tub xeeb ntxwv . Yuav ua li cas rau cov hniav supernumerary?
Puas yog ntau yam tib yam li txhais tau?
Qhov txhais tsis yog ib tus lej tag nrho. Qhov ntau yog qhov txawv ntawm tus lej loj tshaj thiab tus lej tsawg tshaj . IS range also mean? Qhov txawv ntawm qhov qis tshaj thiab qhov siab tshaj plaws. Hauv {4, 6, 9, 3, 7} tus nqi qis tshaj yog 3, thiab qhov siab tshaj plaws yog 9, yog li qhov ntau yog 9 − 3=6.
Puas yog kev sau ntau ntau lossis ntau yam?
Cov npe suav tuaj yeem suav tau lossis suav tsis tau. Feem ntau, feem ntau siv, cov ntsiab lus,ntau daim ntawv kuj tseem yuav muaj cov ntsiab lus Txawm li cas los xij, hauv cov ntsiab lus tshwj xeeb, ntau daim ntawv kuj tuaj yeem yog cov khoom sib xws xws li.
Puas yog detrusor overactivity tib yam li lub zais zis ntau dhau?
Overactive zais zis (OAB) yog ib qho mob uas txhais los ntawm qhov muaj qhov tshwm sim ntawm cov zis thaum tsis muaj cov kab mob uas txheeb xyuas tau. Detrusor overactivity (DO) yog xav tias yog lub luag haujlwm tseem ceeb rau cov tsos mob no .
