Me pēhea te hanga kauwhata tatauranga
He taputapu whakaatu raraunga nui ngā tūtohi tatauranga i roto i ngā momo mara pēnei i te pakihi, te mātauranga, te rangahau, me ētahi atu. Mā te whakamahi i ngā tūtohi, ka taea e tātou te whakahaere i ngā raraunga uaua, kia māmā ake ai te mārama me te tātari. Ka hipokina e tēnei tuhinga te hanga tūtohi tatauranga me ngā mahi taipitopito, tae atu ki te whiriwhiri i te momo tūtohi tika, te kohikohi raraunga, me te whakamahi i ngā taputapu me ngā pūmanawa rerekē.
1. Kia Mārama ki te Kaupapa me te Hiahia mō ngā Whakairoiro
I mua i te waihanga i tētahi kauwhata tatauranga, he mea nui kia mārama koe ki te kaupapa e hiahiatia ana. Kei te hiahia koe ki te whakaatu i ngā au, i ngā whakatairite, i ngā tohatoha, i ngā whanaungatanga rānei i waenga i ngā taurangi? Mā te whakatau i tēnei kaupapa ka āwhina i a koe ki te whiriwhiri i te momo kauwhata tino tika.
2. Te Kohikohi Raraunga
Ko te mahi e whai ake nei ko te kohikohi raraunga. Ka taea te tiki raraunga mai i ngā momo puna, pēnei i ngā rangahau, ngā whakamātautau, ngā tuhinga hītori, ngā pātengi raraunga rānei. Me whakarite kia tika, kia whai pānga hoki ngā raraunga ka kohia e koe ki te kaupapa o te kauwhata e hiahia ana koe ki te waihanga.
2.1. Te Whakapūmau i te Raraunga Tika
Ka taea e ngā hapa o ngā raraunga te arahi ki ngā whakatau hē. Nō reira, he mea nui kia tirohia marietia ngā raraunga. Ko ētahi o ngā mahi ka taea e koe te mahi ko:
– Manatokohia ngā pūtake raraunga: Me whakarite he pono ō pūtake raraunga.
– Te horoi raraunga: Mukua ngā raraunga kāore e tika ana, ngā tāruarua rānei kāore e hiahiatia.
– Te whakataurite raraunga: Me whakarite kia ōrite te whakatakotoranga raraunga hei whakahaere i te tātari.
3. Te Kōwhiri i te Momo Tūtohi Tika
He momo tūtohi rerekē ka taea te whakamahi mō ngā kaupapa rerekē. Anei ētahi momo tūtohi noa me te wā e pai ai te whakamahi:
– Tūtohi Pae: Hei whakatairite i te nui, te auau rānei i waenga i ngā kāwai rerekē.
– Tūtohi Raina: He pai mō te whakaatu i ngā au i roto i te wā.
– Tūtohi Porowhita: He pai mō te whakaatu i ngā ōwehenga, i ngā ōrau rānei.
– Histogram: He mea whai hua mō te whakaatu i te tohatoha o ngā raraunga tonu.
– Kauwhata Marara: He maha ngā wā e whakamahia ana hei whakaatu i te whanaungatanga i waenga i ngā taurangi e rua.
4. Te Whakamahi i te Pūmanawa hei Waihanga Kauwhata
He maha ngā taputapu me ngā pūmanawa ka taea te whakamahi hei hanga kauwhata tatauranga. Ko ētahi o ngā mea rongonui ko:
4.1.Microsoft Excel
Ko Excel tētahi o ngā taputapu e whakamahia whānuitia ana. Anei ngā mahi matua mō te waihanga tūtohi i roto i te Excel:
1. Tāuru Raraunga: Tuhia ō raraunga ki te ripanga.
2. Tīpakohia te Raraunga: Whakamāramahia ngā raraunga e hiahia ana koe ki te tāpiri ki te kauwhata.
3. Tāpiri Tūtohi: Haere ki te ripa 'Whakauru' ka tīpako i te momo tūtohi e hiahiatia ana.
4. Whakarite Tūtohi: Whakaritehia ngā huānga tūtohi pēnei i te taitara, ngā tapanga tuaka, ngā tae, me ētahi atu.
4.2. Pukapuka a Google
Pērā i a Excel, he taputapu whai hua anō hoki a Google Sheets mō te hanga kauwhata tatauranga. He rite tonu ngā mahi taketake ki tā Excel. Ko te painga ko te penapena raraunga a Google Sheets i roto i te kapua, kia taea ai te uru atu mai i hea atu.
4.3. Pūmanawa Tatauranga Motuhake
Mō ngā tātaritanga tatauranga uaua ake, ka taea te whakamahi i ngā pūmanawa pēnei i te SPSS, R, Python rānei me ngā whare pukapuka pēnei i te Matplotlib me te Seaborn. He maha ake ngā kōwhiringa me te ngāwari o ēnei taputapu ki te whakarite me te tātari raraunga.
5. Te Waihanga i ngā Kauwhata Tatauranga
5.1. Te Whakamahi i a Excel
Anei tētahi tauira mō te hanga i tētahi kauwhata pae i roto i te Excel:
1. Whakauruhia ngā Raraunga:
– Whakauruhia te kāwai raraunga ki te pou tuatahi.
– Tāuruhia te uara ki te pou tuarua.
2. Tīpakohia ngā Raraunga:
– Whakamāramahia ngā raraunga e hiahia ana koe ki te whakamahi mō te tūtohi.
3. Whakauruhia ngā Whakairoiro:
– Pāwhiritia te ripa 'Whakauru'.
– Tīpakohia te 'Tūtohi Pae' mai i ngā kōwhiringa tūtohi e wātea ana.
4. Whakaritea ngā Whakairoiro:
– Pāwhiri-matau i tētahi huānga tūtohi hei whakatika.
– Ka taea e koe te tāpiri i te taitara tūtohi, ngā tapanga tuaka, me te poutohu.
5. Te Rokiroki me te Tiritiri:
– Tiakina tō kōnae.
– Mā te Excel ka taea te kaweake i ngā tūtohi hei whakaahua, te whakauru rānei ki roto i ētahi atu tuhinga.
5.2. Te Whakamahi i te R
He reo hōtaka kaha a R mō te tātari tatauranga. Anei tētahi tauira o te hanga i tētahi kauwhata māmā mā te whakamahi i a R:
"`R
Te tāuta i te mōkihi ggplot2 (Mēnā kāore anō kia tāutahia)
tāuta.mōkihi(“ggplot2”)
Kawemai i te whare pukapuka
whare pukapuka(ggplot2)
Raraunga tauira
raraunga <- raraunga.frame( kāwai = c('A', 'B', 'C', 'D'), uara = c(10, 20, 30, 40) ) Tuhia he kauwhata pae ggplot(raraunga, aes(x=kāwai, y=uara)) + geom_bar(stat="tauira") + ggtitle("Tauira Kauwhata Pae") + xlab("Kāwai") + ylab("Uara") ``` 6. Te Whakamārama me te Whakamahinga o ngā Kauwhata Ko te hanga kauwhata te taahiraa tuatahi, engari ko te mea nui ko te whakamahinga me te whakamāramatanga o te kauwhata. Ko ētahi tohutohu mō te whakamārama i ngā kauwhata ko: - Kia Aro ki te Tauine: Kia tika ngā tauine i runga i ngā tuaka poutū me ngā tuaka whakapae mō ō raraunga. - Tātarihia ngā Auahatanga: Kia aro ki te auahatanga whānui i roto i tō kauwhata. - Whakataurite i ngā Kāwai: Ki te whakamahi koe i tētahi kauwhata pae, i tētahi kauwhata porowhita rānei, whakatauritea ngā kāwai ki a rātou anō. - Tāutuhia ngā Mea Tawhiti: Rapua ngā uara e ahua rerekē ana i ngā raraunga whānui, me rangahau anō pea. 7. Ngā Hapa Noa hei Ārai Ko ētahi hapa noa i te hanga kauwhata tatauranga ko: - Te Whakamahi i te Momo Kauwhata Hē: Kāore e pai ngā kauwhata katoa mō ngā momo raraunga katoa. - Te Whakahē i ngā Tapanga: Ki te kore he tapanga mārama mō ngā tuaka, ngā kāwai rānei, ka uaua te mārama ki ngā kauwhata. - He Nui Rawa Ngā Raraunga: Ka taea e ngā kauwhata kī tonu te whakapohehe i ngā kaipānui. - Ngā Raraunga Hē: Me whakarite kia tirohia, kia manatokohia hoki ngā raraunga i mua i te hanga i te kauwhata. Whakamutunga Ko te hanga kauwhata tatauranga whai hua he maha ngā mahi ātaahua, mai i te mārama ki te kaupapa, te kohikohi raraunga, te whiriwhiri i tētahi momo kauwhata, ki te whakamārama i ngā hua. Mā ngā taputapu pēnei i a Excel, Google Sheets, me ētahi atu pūmanawa tatauranga, ka taea e koe te hanga kauwhata e kore e ātaahua noa ki te titiro engari he whai tikanga hoki ki te tātari. Kia mahara ki te tirotiro tonu i ō raraunga, whiriwhiria te kauwhata tika, me te karo i ngā hapa noa hei whakarite kia whai hua, kia whai kōrero hoki ō kauwhata.
