Kushandisa Mode Kuti Uone Kukosha Kunonyanya Kuonekwa
Muhupenyu hwedu hwezuva nezuva, tinowanzo sangana nedata: mamakisi ebvunzo dzevadzidzi, saizi dzeshangu dzinotengeswa zvakanyanya, mhando dzezvigadzirwa zvakakurumbira, uye kunyange huwandu hwezvichemo zvebasa revatengi. Mubvunzo ndewokuti, tingaziva sei zviri nyore kuti ndeapi makoshero kana mapoka anowanzoitika? Imwe pfungwa huru yehuwandu hwemasvomhu inobatsira zvikuru pachinangwa ichi imodhi. Mode inotibatsira kuwana kukosha "kunowanzoitika" museti yedata, zvichiita kuti zvive nyore kuita sarudzo uye kududzira ruzivo.
Nzira Yokunzwisisa
Modhi ndiyo kukosha (kana chikamu) kunowanzoonekwa museti yedata. Kusiyana neavhareji, iyo inobatanidza kukosha kwese uye yobva yagovaniswa nenhamba yemitengo, modhi iyi inotarisa chete pakuwanda kwezviitiko. Modhi iri nyore kunzwisisa nekuti vanhu vanowanzo kwezva values zvakajairika kana zvinowanzoitika.
Semuenzaniso, kana chitoro chikaratidza saizi dzeT-shirt dzinotengwa nevatengi kazhinji: S, M, M, L, M, XL, L, saka saizi M ndiyo nzira nekuti ndiyo inonyanya kuoneka.
Sei Mode Yakakosha?
Maitiro akakosha nekuti:
1. Inomiririra maitiro akajairika: Modhi inoratidza sarudzo inonyanya kukosha kana kukosha.
2. Yakakodzera data rechikamu: Kana data iri muchimiro cherudzi rwezvinhu, ruvara, kana brand, hatigone kuverenga avhareji, asi modhi yacho inogona kutsanangurwa.
3. Zviri nyore uye zvinokurumidza: Kazhinji, nzira yacho inogona kuwanikwa nekuverenga zviitiko zvemutengo wega wega.
4. Zvinobatsira pakuita sarudzo: Semuenzaniso, kusarudza huwandu hwezvinhu zvinoda kuwedzerwa zvichibva pane zvigadzirwa zviri kutengeswa zvakanyanya.
Mudzidzo, nzira dzekudzidzisa dzinogona kubatsira vadzidzisi kuona mamakisi anowanikwa nevadzidzi. Mukushambadzira, nzira dzekudzidzisa dzinobatsira makambani kuona zvigadzirwa zvinonyanya kufarirwa. Muhutano, nzira dzekudzidzisa dzinogona kuratidza zviratidzo zvinowanzoonekwa muvarwere.
Maitiro Ekuziva Maitiro Edata Rimwe Chete
Data rimwe chete idata rinoratidzwa sezvariri pasina kurongwa mumapoka. Matanho ekuona maitiro mudata rimwe chete:
1. Ronga data (zvingasarudzwa, asi zvinoita kuti zvinhu zvive nyore).
2. Verenga kuwanda kwekuitika kwechinhu chimwe nechimwe.
3. Sarudza kukosha kune frequency yakanyanya.
Muenzaniso:
Zvibodzwa zvebvunzo: 70, 80, 80, 90, 60, 80, 70, 75, 90
Kakawanda:
– 60: kaviri
– 70: kaviri
– 75: kaviri
– 80: kaviri
– 90: kaviri
Modhi yacho ndeye 80 nekuti inoonekwa katatu, kakawanda kupfuura chero imwe kukosha.
Mode muBoka Data
Dzimwe nguva panenge paine data rakawandisa rekuti rionekwe muchimiro chetafura yekugoverwa kwema frequency, uko data racho rinoiswa muzvikamu zvekirasi (semuenzaniso, 50–59, 60–69, nezvimwewo). Kune data rakaiswa mumapoka, modhi inosarudzwa kubva mukirasi ine frequency yepamusoro, inonzi mode class. Zvisinei, kuti uwane modhi chaiyo, fomura yemodhi yeboka inoshandiswa.
Matanho Akajairika:
1. Sarudza kirasi ine frequency yepamusoro (kirasi yemode).
2. Shandisa fomura iyi kufungidzira kukosha kwemodhi muchikamu.
Fomura yeModhi yeData reBoka:
\[
Mo = L + \left(\frac{d_1}{d_1 + d_2}\right)\times p
\]
Information:
– \(Mo\) = maitiro
– \(L\) = mupendero wepasi wekirasi yemode
– \(d_1\) = musiyano mukuwanda kwekirasi yemode nekirasi yapfuura
– \(d_2\) = musiyano wehuwandu hwemaitikiro pakati pekirasi yemode nekirasi mushure mayo
– \(p\) = kureba kwekirasi yechinguvana
Muenzaniso:
Tafura yemapoinzi ebvunzo:
| Nguva | Nguva Yakawanda |
|———|————-|
| 50–59 | 5 |
| 60–69 | 8 |
| 70–79 | 12 |
| 80–89 | 9 |
| 90–99 | 6 |
Kirasi yemode i70–79 nekuti ine frequency yakanyanya (12).
Mupendero wepasi wekirasi ye70–79 i69,5 (kana uchishandisa mupendero wekirasi).
Kureba kwekirasi \(p = 10\).
Mafambiro ekirasi yemodhi \(f_m = 12\)
Kakawanda kakare \(f_1 = 8\)
Kuwanda kwezvinoitika mushure me \(f_2 = 9\)
Saka:
– \(d_1 = f_m – f_1 = 12 – 8 = 4\)
– \(d_2 = f_m – f_2 = 12 – 9 = 3\)
\[
Mo = 69,5 + \left(\frac{4}{4+3}\right)\times 10
\]
\[
Mo = 69,5 + \kuruboshwe(\frac{4}{7}\kurudyi)\kawa 10
\]
\[
Mo = 69,5 + 5,714 \inenge 75,214
\]
Saka maitiro edata reboka anenge 75,21.
Mhando dzeModhi: Unimodal, Bimodal, uye Multimodal
Haasi data rese rine modhi imwe chete. Zvichienderana nehuwandu hwezvinhu zvinoonekwa kakawanda, data rinogona kukamurwa kuita:
1. Unimodal: kukosha kumwe chete ndiko kunonyanya kuonekwa.
Muenzaniso: 2, 3, 3, 4, 5 → maitiro = 3
2. Bimodal: kune ma values maviri anowanzoonekwa kakawanda.
Muenzaniso: 1, 2, 2, 3, 3, 4 → maitiro = 2 na 3
3. Multimodal: zvinopfuura zviviri zvinova mode.
Muenzaniso: 1, 1, 2, 2, 3, 3 → maitiro = 1, 2, 3
4. Hapana maitiro: zvese zvinoonekwa nefrequency imwe chete.
Muenzaniso: 1, 2, 3, 4 → hapana maitiro.
Kunzwisisa rudzi rwemode kunotibatsira kududzira hunhu hwedata. Data remhando dzakasiyana, semuenzaniso, rinogona kuratidza kuvapo kwemapoka akasiyana kana mapatani mukati mevanhu vamwe chete.
Zvakanakira uye Zvakaipira zveMode
Zvakawandisa:
- Zviri nyore kwazvo kuverenga, kunyangwe nekuona data riri nyore.
- Inogona kushandiswa paruzivo rwemhando, semuenzaniso ruvara rwaunofarira kana rudzi rwebasa.
– Hazvikanganisike nehukuru hwakanyanya (zvisingawanzoitiki). Kana paine hukuru hukuru kana hudiki, modhi ichiri kumiririra iyo inowanzoitika.
Kekurangan:
- Dzimwe nguva hazvisi zvakasiyana (zvinogona kuva nemaitiro anopfuura rimwe chete kana kusava nemaitiro).
- Hazvimiriri zvakanyanya data rese kana kugoverwa kwedata kwakaoma.
- Mudata reboka, modhi inowanzo kuve fungidziro, kwete kukosha chaiko.
Pasinei nemiganhu yayo, nzira iyi inoramba ichibatsira zvikuru kunyanya kana chinangwa chekuongorora chiri chekuwana maitiro akajairika.
Mienzaniso yekushandiswa kweMode muhupenyu chaihwo
1. Kutengeserana/Kutengesa: Sarudza saizi dzeshangu dzinotengeswa zvakanyanya kuti utarisire masheya.
2. Dzidzo: Kuziva mamakisi anowanzo wanikwa nevadzidzi pakuongorora kudzidza.
3. Hutano: Kuwana zvichemo zvinowanzo bvunzwa mukiriniki nezvekuronga basa.
4. Kutakurwa: Sarudza maawa apo kuzara kwemotokari kunowanzoitika zvichibva pamishumo yezuva nezuva.
5. Ongororo dzemusika nekutsvaga: Tsvaga kuti ndeapi marudzi anowanzo sarudzwa nevanopindura.
Panyaya yekuita sarudzo, nzira dzinobatsira kuisa zvinhu zvinokosha zvichibva pane "zvinowanzoitika" chokwadi.
Mhedziso
Iyo modhi chiyero chetsika yepakati inosarudza kukosha kunowanzoitika kana kuti chikamu museti yedata. Zvakanakira zvayo zviri mukureruka kwayo uye kugona kwayo kuongorora data renhamba nerechikamu. Iyo modhi inogona kuverengerwa kune seti imwe chete yedata nekuverenga kuwanda kwekuitika, nepo kune data rakabatanidzwa, fomura inogona kushandiswa kufungidzira kukosha kwemodhi zvakanyatsonaka. Nekunzwisisa mashandisirwo emamodhi, tinogona kududzira data zvinobudirira uye kuita sarudzo zvichibva pane zvakajairika.
Kana muchida, ndinogonawo kuwedzera mibvunzo yemuenzaniso nehurukuro dzavo kana kugadzira chinyorwa chakanyatsorongeka chebasa rechikoro/koreji.
