Chithunzi Chogawanitsa: Tanthauzo, Ntchito, ndi Kugwiritsa Ntchito
Kumvetsetsa Zithunzi za Scatter
Chithunzi chojambulidwa, chomwe chimadziwikanso kuti chithunzi chojambulidwa kapena chithunzi chojambulidwa, ndi mtundu wa graph womwe umagwiritsidwa ntchito mu ziwerengero ndi kusanthula deta kuti ufotokoze mwachidule ndikuwonetsa ubale pakati pa zosintha ziwiri zopitilira. Chithunzichi chikuwonetsa mfundo za data pa ndege ya Cartesian, pomwe ma axes a x- ndi y aliyense amayimira chosinthika chimodzi. Mfundo iliyonse pa chithunzichi imayimira awiri a ma values awiri omwe awonedwa. Kawirikawiri, zithunzi zojambulidwa zimatithandiza kumvetsetsa mapangidwe, zomwe zikuchitika, ndi mgwirizano womwe ungakhalepo pakati pa zosintha ziwirizi.
Ntchito ya Chithunzi Chogawanitsa
Ma scatter plot ali ndi ntchito zosiyanasiyana pakusanthula deta, zina mwa izo ndi:
1. Kudziwa Ubale: Ma Scatterplot amathandiza kudziwa ngati pali ubale kapena ubale pakati pa zinthu ziwiri. Mwachitsanzo, kuona ngati pali ubale pakati pa kutalika ndi kulemera kwa munthu.
2. Dziwani Zinthu Zakunja: Polemba deta, zinthu zakunja, kapena deta yosiyana kwambiri ndi zina zonse, zitha kuzindikirika mosavuta. Zinthu zakunja zitha kuyambitsidwa ndi zolakwika muyeso kapena zochitika zina zosawerengeka.
3. Kuwona Deta: Ma Scatterplot amalola kuwona mozama, zomwe sizimawonekera nthawi zonse kuchokera patebulo losavuta la deta. Amapereka lingaliro lomveka bwino pa mphamvu ya ubale pakati pa zosintha ndi mawonekedwe a ubalewo, kaya wolunjika, wa quadratic, kapena wosakhazikika.
4. Kuzindikira Mapangidwe ndi Mayendedwe: Pojambula deta pa scatterplot, mapangidwe ndi mayendedwe mu deta amatha kuzindikirika. Mwachitsanzo, zitha kuoneka ngati chosinthika chimatsatira njira inayake yowonjezeka kapena yotsika.
Kugwirizana mu Chithunzi cha Scatter
Mu kusanthula kwa scatterplot, ndikofunikira kumvetsetsa lingaliro la ubale, lomwe limayesa mphamvu ya ubale pakati pa zinthu ziwiri. Ubale ukhoza kukhala wabwino, woipa, kapena zero:
1. Kugwirizana Kwabwino: Kumachitika pamene kuwonjezeka kwa mtengo wa variable imodzi kutsatiridwa ndi kuwonjezeka kwa mtengo wa variable ina. Mu chithunzi, mfundo za deta zidzapanga mzere kapena curve yomwe imakwera kuchokera pansi kumanzere kupita pamwamba kumanja.
2. Kugwirizana Koipa: Kumachitika pamene kuwonjezeka kwa mtengo wa variable imodzi kutsatiridwa ndi kuchepa kwa mtengo wa variable ina. Mu chithunzi, mfundo za deta zimapanga mzere kapena curve yomwe imatsika kuchokera pamwamba kumanzere kupita pansi kumanja.
3. Kusagwirizana Kosatha: Kumachitika pamene palibe ubale womveka bwino pakati pa zinthu ziwiri. Mfundo za deta zidzafalikira mwachisawawa popanda chitsanzo chomveka bwino.
Momwe Mungapangire Tchati Chogawanitsa
Kuti mupange malo otseguka, tsatirani izi:
1. Kusonkhanitsa Deta: Konzani magulu awiri a deta, iliyonse ikuyimira zosintha x ndi y.
2. Dziwani Mulingo ndi Ma Axes: Dziwani mulingo wa x-axis ndi y-axis kutengera kuchuluka kwa zinthu ziwirizi.
3. Deta ya Chiwembu: Lembani ma values awiriawiri a ma variable awiriwa ngati mfundo pa graph.
4. Kusanthula: Yang'anani nkhani kuti mudziwe njira kapena zochitika zomwe zingatheke ndikuwerengera mgwirizano kuti muwunikenso mozama.
Chitsanzo cha Chithunzi cha Scatter
Tiyerekeze kuti tili ndi deta yokhudza kutalika (mu cm) ndi kulemera (mu kg) kwa anthu khumi:
| Kutalika (cm) | Kulemera kwa Thupi (kg) |
|——————-|——————|
| 160 | 55 |
| 165 | 60 |
| 170 | 65 |
| 175 | 70 |
| 180 | 75 |
| 185 | 80 |
| 190 | 85 |
| 195 | 90 |
| 200 | 95 |
| 205 | 100 |
Pojambula deta iyi pa chithunzi chobalalitsa, tidzaona kuti pali mgwirizano wabwino pakati pa kutalika ndi kulemera.
Kugwiritsa Ntchito Zithunzi za Scatter Padziko Lonse
Ma diagram a Scatterplot amagwiritsidwa ntchito m'magawo ndi mafakitale osiyanasiyana kuti afufuze deta mozama. Zitsanzo zina zenizeni ndi izi:
1. Thanzi: Kudziwa ubale womwe ulipo pakati pa zinthu zosiyanasiyana zaumoyo monga zakudya ndi kuthamanga kwa magazi, kapena nthawi yogona komanso kuchuluka kwa ntchito zomwe munthu amachita tsiku ndi tsiku.
2. Zachuma: Kusanthula ndalama zomwe zayikidwa ndi phindu, kuyang'ana ubale womwe ulipo pakati pa zinthu monga chiwongola dzanja ndi kukwera kwa mitengo.
3. Maphunziro: Kuyesa mgwirizano pakati pa nthawi yophunzira ndi zigoli za mayeso a ophunzira kuti mumvetse zinthu zomwe zimakhudza momwe ophunzira amagwirira ntchito.
4. Bizinesi: Mu malonda, yesani kugwira ntchito bwino kwa kampeni yotsatsa malonda poganizira ndalama zomwe zimagulitsidwa poyerekeza ndi kuchuluka kwa malonda.
Zofooka za Zithunzi Zofalikira
Ngakhale kuti pali zabwino zambiri, malo osungiramo zinthu zakale ali ndi zofooka zina:
1. Sichifotokoza Chifukwa: Kugwirizana komwe kumawoneka mu scatterplot sikutanthauza ubale wa chifukwa ndi zotsatira. Kugwirizana kumangosonyeza kuti pali ubale, koma sikufotokoza chifukwa kapena njira ya ubalewo.
2. Zovuta pa Deta Yaikulu Kwambiri: Pankhani ya deta yayikulu kwambiri, malo odulira amatha kukhala okhuthala kwambiri moti zimakhala zovuta kuwamasulira.
3. Zosintha Ziwiri Zokha: Chithunzi chojambulidwa chimangowonetsa ubale pakati pa zosinthika ziwiri. Pa maubwenzi okhudzana ndi zosinthika zoposa ziwiri, njira zowunikira zambiri zimafunika.
Mapeto
Ma Scatterplot ndi chida champhamvu mu ziwerengero ndi kusanthula deta kuti tiwone ndi kusanthula ubale pakati pa zinthu ziwiri. Mwa kuthandizira kuzindikira mgwirizano, zochitika, ndi zinthu zina zosiyana, zimathandiza kumvetsetsa bwino deta. Ngakhale kuti ali ndi zofooka zina, kugwiritsa ntchito bwino ma scatterplot kungapereke chidziwitso chofunikira chomwe chimathandizira kupanga zisankho zabwino m'magawo osiyanasiyana. Kumvetsetsa momwe mungapangire ndikusanthula ma scatterplot ndi luso lofunikira kwa aliyense wogwira ntchito ndi deta.
