Mibvunzo yemuenzaniso nekukurukurirana kweMode neMedian
Modhi nepakati ipfungwa mbiri dzehuwandu dzinoshandiswa kakawanda mukuongorora data. Dzese dzinopa ruzivo nezvepakati pekugoverwa kwedata, asi nenzira dzakasiyana. Muchinyorwa chino, tichakurukura tsananguro, maverengero, uye mienzaniso, pamwe nekukurukurirana kwepfungwa idzi mbiri.
Tsanangudzo yeMode uye Median
maitiro
Iyo modhi ndiyo kukosha kunowanzoonekwa mu data set. Kana zvese kukosha mu data set zvichionekwa ne frequency yakafanana, saka zvinogona kutaurwa kuti hapana modhi mu data set. Datasets dzinogona kuva ne mode imwe (unimodal), mode mbiri (bimodal), kana mode dzinopfuura mbiri (multimodal).
Median
Mupakati (median) inhamba yepakati (mid-value) mudata rakarongwa kubva padiki kusvika pakuru. Kana nhamba yemapoinzi edata isina kuenzana (odd), mupakati (median) inhamba yepakati (mid-value). Kana nhamba yemapoinzi edata yakaenzana, mupakati (median) inhamba yepakati (mid-values) mbiri.
Muenzaniso weMibvunzo yeMode
Mubvunzo 1:
Zvichienderana nedata rakarongwa: 3, 5, 7, 7, 9, 10, 10, 10. Sarudza maitiro edata racho.
Kukurukurirana:
Tinofanira kuwana mavalues anowanikwa kakawanda mu data iri. Kubva pa data iri:
- 3 inoonekwa kamwe chete
- 5 inoonekwa kamwe chete
- 7 inoonekwa kamwe chete
- 9 inoonekwa kamwe chete
- 10 inoonekwa kamwe chete
Saka, kukosha kunowanzoonekwa i10. Saka, nzira yedata iri i10.
Mubvunzo 2:
Seti yedata inotevera inopiwa: 4, 4, 6, 8, 8, 8, 9, 9. Sarudza maitiro edata.
Kukurukurirana:
Tinofanira kuwana mavalues anowanikwa kakawanda mu data iri. Kubva pa data iri:
- 4 inoonekwa kamwe chete
- 6 inoonekwa kamwe chete
- 8 inoonekwa kamwe chete
- 9 inoonekwa kamwe chete
Saka, kukosha kunowanzoonekwa i8. Saka, nzira yedata iri i8.
Mibvunzo yeMienzaniso yepakati
Mubvunzo 1:
Zvichienderana nedata rakarongwa: 3, 5, 7, 9, 11. Sarudza pakati pedata.
Kukurukurirana:
Kutanga, ronga data reseti nenzira yekukwira (kana risati ragadziriswa). Muchiitiko ichi, data reseti ragadziriswa kare. Sezvo paine nhamba isingawanzoonekwi yemapoinzi edata (5), median ndiyo kukosha kwepakati, inova kukosha kwechitatu.
Saka, avhareji yedata iri i7.
Mubvunzo 2:
Zvichienderana nedata rakarongwa: 2, 4, 6, 8, 10, 12. Sarudza pakati pedata.
Kukurukurirana:
Kutanga, ronga data nenzira yekukwira kana risati ragadziriswa. Muchiitiko ichi, seti yedata inenge yatorongwa. Sezvo paine nhamba yedata yakaenzana (6), iyo yepakati ndiyo avhareji yemitengo miviri yepakati, inova yechitatu neyechina.
Saka, muyero wepakati ndewe (6 + 8) / 2 = 7.
Mibvunzo pamusoro peKubatanidza Mode neMedian
Mubvunzo 1:
Zvichienderana nedata rakarongwa: 15, 13, 15, 10, 13, 14, 15, 12, 12. Sarudza maitiro uye pakati pedata.
Kukurukurirana kweModhi:
- 10 inoonekwa kamwe chete
- 12 inoonekwa kamwe chete
- 13 inoonekwa kamwe chete
- 14 inoonekwa kamwe chete
- 15 inoonekwa kamwe chete
Saka modhi yedata iri ndeye 15 nekuti inowanzoonekwa (katatu).
Kukurukurirana kwepakati:
Ronga data: 10, 12, 12, 13, 13, 14, 15, 15, 15.
Nhamba yedata haina kujairika (9 data), saka median ndiyo kukosha kwepakati, kureva kukosha kwechishanu (5th).
Saka avhareji yedata iri i13.
Mubvunzo 2:
Zvichienderana nedata rakarongwa: 7, 8, 8, 5, 3, 3, 3, 6, 4. Sarudza maitiro uye pakati pedata.
Kukurukurirana kweModhi:
- 3 inoonekwa kamwe chete
- 4 inoonekwa kamwe chete
- 5 inoonekwa kamwe chete
- 6 inoonekwa kamwe chete
- 7 inoonekwa kamwe chete
- 8 inoonekwa kamwe chete
Saka modhi yedata iri ndeye 3 nekuti inowanzoonekwa (katatu).
Kukurukurirana kwepakati:
Ronga data: 3, 3, 3, 4, 5, 6, 7, 8, 8.
Nhamba yedata haina kujairika (9 data), saka median ndiyo kukosha kwepakati, kureva kukosha kwechishanu (5th).
Saka avhareji yedata iri i5.
Mhedziso
Modhi nepakati inzira dzese dzekuziva pakati peseti yedata, asi dzine mashandisirwo akasiyana. Modhi inobatsira mumamiriro ezvinhu apo tinoda kuziva kukosha kunowanzoitika, nepo median ichipa kukosha kwepakati kunoparadzanisa pamusoro nepasi peseti yedata nehuwandu hwakaenzana hwemapoinzi edata, zvichiita kuti ibatsire zvikuru pakubata nezvinhu zvisingawanzoitiki.
Kunzwisisa maverengero nekushandisa pfungwa idzi mbiri inyanzvi yakakosha mukuongorora data remasvomhu. Nemienzaniso nehurukuro dzakapihwa, tinovimba kuti zvichave nyore kudzidza maverengero emodhi nepakati mumamiriro akasiyana-siyana uye seti dzedata. Tinovimba kuti chinyorwa chino chave chichibatsira mukuwedzera ruzivo rwako rwemasvomhu.
