Wake wazibuza ukuthi ubalwa kanjani umdidiyeli kusuka kusethi yezinombolo? Kulesi sihloko sizochaza isinyathelo ngesinyathelo indlela yokwenza. Bala umdidiyeli kuyikhono lezibalo eliwusizo elizokuvumela ukuthi uthole inani elimaphakathi kusethi yedatha. Ukuthi uxazulula izinkinga zezibalo noma unentshisekelo yokufunda okuthile okusha, ukwazi ukuthola umdidiyeli Kuyoba ithuluzi elibalulekile. Qhubeka ufunde ukuze uthole ukuthi ubalwa kanjani umdidiyeli kalula futhi ngokushesha.

- Isinyathelo ngesinyathelo ➡️ Ungayithola kanjani i-median

Indlela yokuthola i-median

• Okokuqala, hlela izinombolo ngendlela ekhuphukayo noma eyehlayo.
• Bese, thola inombolo ephakathi ohlwini.
• Uma inombolo yezinombolo iyinqaba, i-median iyinombolo ephakathi nohlu.
• Uma inombolo yezinombolo ilingana, i-median iyisilinganiso sezinombolo ezimbili eziphakathi nendawo.
• Ekugcineni, hlola umphumela wakho ukuze uqiniseke ukuthi ubale imidiyeni ngendlela efanele.

Imibuzo Nezimpendulo

Imibuzo Evame Ukubuzwa Mayelana Nendlela Yokuthola I-Median

1. Iyini i-median kwizibalo?

I-median ithi:

– Inani elimaphakathi lesethi yedatha e-odwe kusukela kwencane kakhulu kuye kwenkulu kunazo zonke.

2. I-median ibalwa kanjani?

Ukuze ubale i-median, landela lezi zinyathelo:

– Oda idatha kusukela kokuncane kuya kokukhulu.
– Uma isethi yedatha iyinqaba, i-median iyinani eliphakathi nendawo.
– Uma isethi yedatha ilingana, i-median iyisilinganiso samanani amabili aphakathi nendawo.

3. Ithini ifomula yokuthola umdidiyeli?

Ifomula yokubala i-median ithi:

– Uma isethi yedatha iyinqaba, i-median = inani phakathi nendawo.
– Uma isethi yedatha ilingana, i-median = (inani elimaphakathi 1 + inani lesikhungo 2) / 2.

4. Uyini umehluko phakathi kwe-medium ne-medium?

Umehluko uthi:

– Isilinganiso isilinganiso sesethi yedatha, kuyilapho imidiyeni iyinani eliphakathi.

5. Kuyini ukubaluleka kwe-median ezibalweni?

Ukubaluleka kwe-median kwizibalo ukuthi:

– Ayizweli kangako kumanani adlulele kusethi yedatha, okuyenza iqine kakhulu kunencazelo.

6. Yiziphi izinhlobo zedatha ezingabalwa i-median?

Ungakwazi ukubala i-median ye:

– Idatha yezinombolo, efana neminyaka, imali engenayo, nezikolo, phakathi kokunye.

7. I-median isetshenziswa kanjani ekuphileni kwansuku zonke?

I-median isetshenziswa ekuphileni kwansuku zonke ukuze:

– Bala iholo lomndeni elimaphakathi, iminyaka emaphakathi eqenjini, kanye nezikhathi zokulinda ezimaphakathi, isibonelo.

8. Ingabe i-median iyafana nemodi yezibalo?

Cha, i-median nemodi yilezi:

– Imiqondo ehlukene kwizibalo. I-median iyinani eliphakathi, kuyilapho imodi iyinani elivame kakhulu kusethi yedatha.

9. Ngingayithola kanjani i-median ku-Excel?

Ukuze uthole i-median ku-Excel, landela lezi zinyathelo:

– Khetha idatha ofuna ukubala i-median yayo.
– Bhala ifomula =MEDIAN(idatha) kuseli.
– Cindezela u-Enter futhi uzothola inani le-median.

10. Yimaphi amaphutha avamile lapho kubalwa i-median?

Lapho ubala i-median, gwema ukwenza amaphutha alandelayo:

– Unga-ode idatha kusukela kokuncane kuye kokukhulu kakhulu ngaphambi kokubala i-median.
– Ukwehluleka ukukhomba kahle amanani abalulekile kusethi yedatha elinganayo.
