Muizvi blog post, ngatinyure mune iyi pfungwa nayo muenzaniso wezita rechiyero kuti vanzwisise kukosha kwayo mukuronga nekuturikira ruzivo nemazvo.

Chii chinonzi Nominal Scale?
Tsanangudzo YeNominal Scale
Chikero chezita (nominal scale) imhando yechipimo chechiyero umo nhamba kana mavara anoshandiswa kupatsanura kana kuziva zvinhu, asi nhamba dzacho pachadzo hadzina nhevedzano yomuzvarirwo kana kuti revo. Mune mamwe mazwi, anongori ma tag kana mavara anoisa data mumapoka akasiyana.
- Semuenzaniso, kana uchiisa muchero michero, unogona kungozvinyora se "apuro," "bhanana," "orenji," or "grapefruit." Kurongeka kwadzakaitwa hakuna basa.
Hunhu hweNominal Scale
Heano mamwe emhando dzakakosha dzezita rezvikero:
- Unhu: Nhamba hadziratidzi huwandu kana hukuru, dzinongoita semavara. Panzvimbo yekuyera huwandu, vanoisa pamberi pekuona mhando yechinhu, "chii" panzvimbo ye "ngani".
- Categorical: Dhata rakakamurwa kuita zvikamu zvakasiyana, zvakasarudzika pasina kupindirana. Chinhu chimwe nechimwe chiri chechikamu chimwe chete.
- Zvisina kurongeka: Zvikamu hazvina kurongeka kana chinzvimbo. Semuenzaniso, maziso e "blue" uye "girinhi" haasi nani kana kuipa, akangosiyana.
- Arbitrary labels: Nhamba kana mavara akagoverwa kumapoka angori mazita uye anogona kuchinjwa pasina kukanganisa zvinoreva data. Kudzokorodza "1" ku "apuro" muchikamu chemichero hakuchinje musimboti.
- Mabasa mashoma emasvomhu: Unogona chete kuita masvomhu sekuwedzera kana kubvisa pane zita rezita kana manhamba aine chirevo chehuwandu. Iwe unogona chete kuverenga kuti zvingani zvinhu zvinowira muchikamu chimwe nechimwe.
- Inotsanangura, kwete kuenzanisa: Vanotsanangura kugoverwa kwedata mukati mezvikamu, asi kwete ukuru kana kurongeka pakati pavo. Iwe unogona kutaura kuti vangani vanhu vanofarira pizza imwe neimwe, asi kwete kutaura kuti mumwe munhu "anoda" pepperoni kupfuura imwe topping.
Mazita ezvikero ndiwo hwaro hwekunzwisisa ekutanga data mapatani uye zvikamu. Kunyange vaine zvisingakwanisi mukuongorora kwakadzama, vanoita basa rakakosha mukuunganidza data uye kuongorora kwekutanga.
Kusiyanisa Nominal Scale Kubva Kune Mamwe Marudzi Ezvikero
Kunzwisisa mutsauko uripo pakati pezita uye mamwe marudzi ezviyero zviyero zvakakosha pakuongorora data nemazvo.
Nominal vs. Ordinal:
- Zita: Hapana kurongeka kwemukati, zvikamu chete (semuenzaniso, ruvara rweziso - bhuruu, brown, girini). Iwe haugoni kuti "brown is better than blue."
- Ordinal: Zvikamu zvine kurongeka, asi mutsauko uripo pakati pawo hauzivikanwe (semuenzaniso, chiyero chekugutsikana - kugutsikana kwazvo, kugutsikana, kusagutsikana). Unogona kuti "kugutsikana kwazvo" zviri nani pane "kugutsikana," asi kwete zviri nani.
Iwe unogonawo kufarira: Ordinal Scale Muenzaniso
Nominal vs. Interval:
- Nominal: Hapana kurongeka, zvikamu chete.
- Chinguva: Zvikamu zvine kurongeka, uye musiyano uripo pakati pawo unowirirana (semuenzaniso, tembiricha muCelsius/Fahrenheit). Unogona kuti 20°C iri 10° kupisa kupfuura 10°C.
Iwe unogonawo kufarira: Interval Scale Measurement
Nominal vs. Ratio:
- Zita: Hapana kurongeka, zvikamu chete.
- Ratio: Zvikamu zvine kurongeka uye zero point yechokwadi (semuenzaniso, kureba mumamita/tsoka). Unogona kuti 1.8m inoreba zvakapetwa kaviri se0.9m.
Yeuka:
- Iwe unogona kushandura zita rezita kune mamwe zvikero chete kana iwe ukarasikirwa neruzivo (semuenzaniso, zita rekuti ordinal, unorasikirwa neruzivo rwekurongeka).
- Ruzivo rwakawanda rwunofambiswa nechikero (nguva, nguva, reshiyo), ndipo pakanyanya kuomarara uye kune simba kuongorora kwaunogona kuita.
- Kusarudza chiyero chakakodzera zvinoenderana nemubvunzo wako wekutsvagisa uye nzira dzekuunganidza data.
Heino fananidzo:
- Fungidzira kuisa michero. Nominal - iwe unongoisa mumapoka (apuro, bhanana). Ordinal - unovaisa nekutapira (1 - zvishoma, 5 - yakawanda). Interval - unoyera shuga yemukati (0-10 gramu). Ratio - unofananidza shuga yemukati, accounting yechokwadi zero (hapana shuga).
Mienzaniso YeNominal Scale
Heano mimwe mienzaniso yakajairika yemazita ezvikero, anofukidza akasiyana siyana ehupenyu hwedu:
