Tauira o ngā Pātai Kōrero mō te Histogram
He whakaaturanga kauwhata te histogram o te tohatoha o tētahi huinga raraunga tau. He rite te histogram ki tētahi tūtohi pae, engari e tohu ana i ngā raraunga kua whakarōpūtia ki ngā awhe motuhake (ngā ipu) ā, he maha ngā wā e whakamahia ana i roto i ngā tatauranga hei whakaatu i ngā tohatoha auau.
I roto i tēnei tuhinga, ka matapakihia e mātou ngā tauira pātai me ngā kōrero mō ngā histogram hei whakapai ake i tō mātou māramatanga ki te hanga me te tātari i ngā histogram.
He aha te Histogram?
He taputapu whakaatu te histogram e whakaatu ana i te tohatoha auau o tētahi huinga raraunga. Ka wehea te whānuitanga o ngā uara ki ngā wā e kiia nei ko ngā "ipu", ā, ka tatauhia te maha o ngā pūwāhi raraunga i roto i ia ipu kia māmā ake ai te tātari. Mā tēnei ka āwhina i te mārama ki te tohatoha me ngā tauira i roto i ngā raraunga.
He maha ngā mahi taketake hei waihanga i tētahi histogram:
1. Kohikohi Raraunga: Tikina he kohinga raraunga hei tātaritanga.
2. Whakatauhia te Awhe Raraunga: Whakatauhia te awhe o ngā uara mai i te raraunga iti ki te raraunga nui.
3. Tīpakohia te maha o ngā ipu para: Whakatauhia te maha o ngā wā, ngā ipu rānei e hiahiatia ana e koe.
4. Auautanga Tatau: Tatauhia te maha o ngā raraunga ka taka ki roto i ia ipu.
5. Tuhia he Histogram: Waihangahia he kauwhata pae e whakaatu ana i te auau o ngā raraunga i roto i ia ipu.

E whakaatu ana tēnei kauwhata i tētahi tohatoha raraunga paku rerekē i tō te tauira o mua.
Kōrero Anō
Mā ngā kauwhata tohu ka taea te whakaatu ā-kanohi i ngā tohatoha auau, engari i ētahi wā ka rerekē ngā hua i runga i te maha o ngā ipu kua tīpakohia. Mā te whakarerekē i te maha o ngā ipu ka rerekē te āhua o te tohatoha, ka pā pea tēnei ki te whakamaoritanga raraunga.
Ngā Mea Hira mō te Hanga i tētahi Histogram
1. Te Kōwhiringa o te Tau o ngā Ipu Para
Ki te iti rawa ngā ipu, ka huna pea ngā taipitopito o te raraunga, ki te maha rawa hoki o ngā ipu, ka uaua rawa te mārama ki te histogram.
2. Te Whakamārama Raraunga
Mā ngā kauwhata ka taea e tātou te kite i ngā tauira tohatoha, pērā i te mea kei te tohatoha noa ngā raraunga, kei te piko ki te taha maui, kei te piko rānei ki te taha matau. He mea whai hua tēnei mō ngā tātaritanga tatauranga atu anō.
3. Tauine ōrite
Me whakarite kia ōrite te whānui o ngā ipu para kia kore ai e hē te whakaaturanga o te histogram.
4. Auautanga, Kiato rānei
Mena he rerekē te rahi o ngā raraunga, he pai ake pea te whakamahi i te kiato i te auau parakore hei whakatairite i ngā huinga raraunga rerekē.
Whakamutunga
He taputapu kaha ngā histogram mō te whakaatu i te tohatoha o ngā raraunga tau. I roto i tēnei tuhinga, kua hipokina e mātou ngā mahi taketake mō te waihanga i tētahi histogram, ā, kua tirohia hoki ngā tauira raruraru e pā ana ki te whakatau i tētahi histogram mai i ngā raraunga kua hoatu. Mā te mārama pai ki ngā histogram ka āwhina i a mātou ki te tātari raraunga kia pai ake ai, me te whakatau whakatau pai ake i runga i taua raraunga.
Mā te mahi tonu ki te waihanga me te tātari i ngā histogram me ngā momo raraunga rerekē me ngā tau o ngā ipu rerekē ka whakapakari i tō tātou kaha ki te whakamahi i tēnei taputapu tatauranga nui. Me whakamātau tonu, me te tūhura i ngā āhuatanga rerekē o ngā histogram kia pai ake ai te tūhura i ō raraunga.
