Leeme la Lebidi la Roulette
Lebidi la roulette le nang le leeme le rata mekotlana e meng ka lebaka la bofokodi ba motjhini: lepheko le hlephileng, rotor e sa lekaneng, mekotlana e senyehileng. Leeme la lebidi la roulette le teng mme le kile la sebediswa. Bothata ke hore lebidi le lokileng ka botlalo le hlahisa “dinomoro tse tjhesang” kamehla, kahoo potso ha se mohla e leng hore na nomoro e a tjhesa, empa ke hore na paterone yohle e sekame ho feta kamoo monyetla o dumellang.
1. Nka sampole ya lebidi le lokileng
Dipotoloho tse nkilweng lebiding le etsisitsweng le se nang leeme ho hang. Fetola boholo ba sampole mme o shebe mokotlana o tjhesang ka ho fetisisa.
2. Tse bonweng kgahlanong le tse lebelletsweng
Bara ka nngwe ke mokotlana ka tatelano ya lebidi. Mola wa matheba ke palo e lebelletsweng, n/37. Sebaka se nang le moriti ke ±2 diphapang tse tlwaelehileng: lebiding le lokileng e ka bang mokotlana o le mong ho e mashome a mabedi o tla tswa ka ntle ho sona ka monyetla feela.
3. Teko ya chi-square
Teko e kopanya hore na mokotlana ka mong o hole hakae le tebello, ka sekwere mme o lekantswe. Lebiding le lokileng kakaretso e latela kabo ya chi-square ka degrees of freedom tse 36; p-value e ka tlase ho 0.05 ka tlwaelo e bitswa ya bohlokwa.
n = 370 · E = 10.00 · χ² = 32.80 · p = 0.622
4. O ka hloka dipotoloho tse kae
Dipotoloho tse hlokehang ho fumana mokotlana o le mong o tswang kgafetsa ho feta 1/37, boemong ba 5% ba lehlakore le le leng ka matla a 80%. Mokotlana o tswang 1 ho tse 35 ho e na le 1 ho tse 37 e ka ba molemo o matla bakeng sa sebapadi, mme ho nka dipotoloho tse mashome a dikete tse ngotsweng ho o netefatsa.
