A tsis zoo correlation txhais tau hais tias muaj inverse kev sib raug zoo nruab nrab ntawm ob qhov sib txawv - thaum ib qho hloov pauv tau txo qis, lwm qhov nce ntxiv.
Hauv qhov no, qhov kev sib raug zoo linear tsis zoo li cas?
Qhov tawg ntawm txoj kab yog me me, yog li muaj zog linear kev sib raug zoo . Txoj kab nqes ntawm txoj kab yog tsis zoo (cov nqi me me ntawm X sib haum rau qhov loj ntawm Y; qhov loj ntawm X sib raug rau qhov me me ntawm Y), yog li muaj tsis zoo cov- kev sib raug zoo (yog, a tsis zoo correlation ) ntawm X thiab Y.
Qhov piv txwv ntawm kev sib raug zoo thiab tsis zoo yog dab tsi? Hauv ib kev sib raug zoo , ob qhov sib txawv txav mus rau tib qho kev taw qhia. Rau piv txwv , muaj a kev sib raug zoo nruab nrab ntawm kev haus luam yeeb thiab haus cawv. Raws li kev haus cawv ntau ntxiv, kev haus luam yeeb zoo li cas. Thaum ob qhov sib txawv muaj ib tsis zoo correlation , lawv muaj inverse kev sib raug zoo.
Ua li no, qhov txawv ntawm qhov zoo thiab qhov tsis zoo linear correlation yog dab tsi?
Nyob rau hauv ib tug tsis zoo correlation , cov variables txav hauv inverse, los yog opposite, cov lus qhia. Hauv lwm lo lus, raws li ib tug kuj nce mus nce los, lwm yam kuj nce mus nce los. Thaum ob qhov sib txawv muaj ib kev sib raug zoo , nws txhais tau hais tias cov variables txav hauv tib txoj kev. Qhov no txhais tau hais tias raws li ib qho kev sib txawv nce, ib yam li lwm tus.
Dab tsi scatterplot qhia tau hais tias muaj kev cuam tshuam tsis zoo?
Muaj ob hom kev sib raug zoo : positive thiab tsis zoo . Variables uas zoo kev sib raug zoo txav mus rau tib qho kev taw qhia, thaum hloov pauv uas tsis zoo kev sib raug zoo txav mus rau qhov sib txawv. Yog tias tsis muaj kev sib raug zoo ntawm ob qhov sib txawv, ces tsis muaj kev sib raug zoo.

Qhov zoo thiab qhov tsis zoo ntawm Mercator projection yog dab tsi?
Disadvantages: Mercator projection distorts qhov loj ntawm cov khoom raws li lub latitude nce los ntawm Equator mus rau tus ncej, qhov twg lub teev yuav infinite. Yog li, piv txwv li, Greenland thiab Antarctica tshwm sim ntau dua qhov txheeb ze rau thaj av loj nyob ze ntawm txoj kab nruab nrab tshaj li qhov lawv muaj tiag
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm cov tsiaj cloning?
Daim ntawv teev cov Disadvantages ntawm Cloning Tsiaj Cloning tsiaj yog qhov tsawg kawg nkaus txoj kev tsim cov me nyuam. Cloning tsiaj yog kim. Cloning tsiaj txo cov noob caj noob ces ntawm cov tsiaj ntawd. Cloning tsiaj thaum kawg yuav qeeb tus nqi ntawm kev yug me nyuam
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm AC tshaj DC?
Nyob rau hauv AC kis tau tus mob system, lub hwj chim yuav kis tau nyob rau hauv ntev nyob deb thiab nyob rau hauv DC transmisson system, qhov poob yog tsawg. Nyob rau hauv AC kis tau tus mob system, lub hwj chim yuav kis tau nyob rau hauv ntev nyob deb thiab nyob rau hauv DC transmisson system, qhov poob yog tsawg
Qhov zoo thiab qhov tsis zoo ntawm tsheb npav topology yog dab tsi?
Qhov zoo thiab qhov tsis zoo ntawm lub tsheb npav network Qhov tsis zoo ntawm lub tsheb npav network yog: yog tias lub xov tooj tseem ceeb tsis ua haujlwm lossis raug puas tsuaj tag nrho lub network yuav poob. Raws li ntau lub chaw ua haujlwm txuas nrog kev ua haujlwm ntawm lub network yuav qeeb qeeb vim cov ntaub ntawv sib tsoo
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
