3. Maitiro ekuverenga Z mucherechedzo muGoogle Sheets kune data set?

Kuti uverenge chibodzwa cheZ muGoogle Sheets seti yedata, tevera matanho aya:

1. Isa data rako muspredishiti muGoogle Sheets.
2. Verenga zvinoreva data rako uchishandisa fomula = AVERAGE(dhata renji).
3. Verenga kutsauka kwakajairwa kwedata rako uchishandisa formula =STDEV(dhata renji).
4. Bvisa zvinoreva kubva kune yega yega kukosha mune yako data uye patsanura mhedzisiro neyakajairwa kutsauka. Izvi zvinokupa iwe Z mamakisi kune yega data.

4. Nzira yekududzira sei chibodzwa cheZ muGoogle Sheets?

Kududzira chibodzwa cheZ muGoogle Sheets kwakakosha kuti unzwisise zvinoreva kukosha. Chibodzwa chakanaka Z chinoratidza kuti data riri pamusoro pezvinoreva, nepo Z isina kunaka inoratidza kuti data iri pazasi pezvinoreva. Iyo yakakwira iyo yakazara kukosha kweiyo Z mamakisi, iyo inoenderera iyo data kubva kune inorehwa.

5. Chii chinonzi Z chibodzwa chinoshandiswa muGoogle Sheets?

6. Ndeipi fomula yekuverenga Z zvibodzwa muGoogle Sheets?

Iyo fomula yekuverenga Z muGoogle Sheets ndeiyi inotevera:

Z = (X – μ) / σ

Ipo Z iri chibodzwa cheZ, X ndiyo yakakosha data, μ ndiyo zvinoreva data, uye σ ndiyo yakajairwa kutsauka kwedata.

7. Chii chakakosha cheZ chibodzwa muhuwandu?

Muzviverengero, mucherechedzo weZ wakakosha nekuti unokubvumidza kuti uenzanise kukosha pazvikero zvakasiyana kana mayuniti, tsvaga zvinobuda, uye unzwisise kugovera uye kusiyanisa kwedata rakaiswa nenzira kwayo. Izvo zvakakoshawo pakuongorora kwakajairwa uye kuita sarudzo inotungamirwa nedata.

8. Ndeapi mashandisirwo ezvibodzwa Z muGoogle Sheets?

Chibodzwa cheZ muGoogle Sheets chine akawanda maapplication, anosanganisira kuongororwa kwedata, tsvakiridzo yesainzi, kuita sarudzo dzebhizinesi, kuongororwa kwemari, uye kuongororwa kwemaitiro munzvimbo dzakasiyana.

9. Maitiro ekushandisa manhamba mabasa muGoogle Sheets kuverenga Z mamakisi?

Kuti uverenge chibodzwa cheZ muGoogle Sheets uchishandisa manhamba mabasa, tevera matanho aya:

1. Isa data rako muspredishiti muGoogle Sheets.
2. Shandisa iyo =AVERAGE(datarange) basa kuverenga zvinoreva.
3. Shandisa iyo =DEVEST(data renji) basa kuverenga kutsauka kwakajairwa.
4. Shandisa fomula =(X - μ) / σ kuverenga chibodzwa cheZ chepoindi yega yega data, apo X ndiyo kukosha kwega, μ ndiyo inoreva, uye σ ndiyo yakajairwa kutsauka.

10. Ndokupi kwandingawane rumwe ruzivo nezve Z-score muGoogle Sheets?

Unogona kuwana rumwe ruzivo nezve chibodzwa cheZ muGoogle Sheets mune zvidzidzo zvepamhepo, Google Sheets maforamu ekubatsira, mabhuku ehuwandu, uye zviwanikwa zvedzidzo pakuongorora data uye nhamba.

Ndichakuwona gare gare, Tecnobits! Rangarira kuti muGoogle Sheets unogona kuverenga iyo Z mamaki nyore. Tinoverenga nokukurumidza.
