Mo tēnei tātaitai
mean absolute deviation (MAD) is the average distance between each value and the mean, using absolute values so distances never cancel out. It measures spread like the standard deviation but is simpler and less sensitive to outliers, because it does not square the deviations. This calculator reports the MAD together with the mean, range and the sum of absolute deviations it was measured from. This calculator reports the MAD together with the mean, range and the sum of absolute deviations it was measured from. This calculator is easy to explain to a non-technical audience and it is easy to trace every value’s distance so that you can find the result.The MAD is 12 ÷ 5 = 2.4 — on average each value sits 2.4 units from the mean.The method is direct: find the mean, take the absolute value of each value’s distance from it, add those distances up and divide by the number of values.Worked example: for 2, 4, 6, 8, 10The MAD is 12 ÷ 5 = 2.4The MAD is 12 ÷ 5The MAD is 12 ÷ 5 = 2.4The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12 ÷ 5The MAD is 12
Ko nga pātai e pā ana
He pēhea te rerekētanga o MAD i te whakarerekētanga paerewa?
Ko te MAD e whakawaenga ana i ngā whakarerenga tūturu, i te wā e whakawaenga ana te whakarerenga paerewa i ngā whakarerenga tapawhā, kātahi ka mau i tētahi pūtake tapawhā. Nā te mea kāore e tapawhā, ka tuku te MAD i te taumaha ake ki ngā tātai, ā, he ngāwari kē atu te whakamārama, engari he āhua pāngarau kē atu te whakarerenga paerewa.
He pēhea te tatau i a au i te MAD mā te ringa?
Ka kitea te tauwaenga, ka tangohia i ia uara, ka tangohia te uara tūturu o ia hua, kātahi ka whakawaengatia ēnei tawhiti. Mō te 2, 4, 6, 8, 10 ko te tauwaenga ko te 6, ā, ko te MAD (4+2+0+2+4)/5 = 2.4.
He ōrite te rerekētanga tūturu ki te rerekētanga ā-roto?
Heoi anō, ko ngā kupu e rua e tohutoro ana ki te mea kotahi: ko te tau tōpū o ngā tawhiti tūturu mai i tētahi pito matua, ko te nuinga o te wā, ko te tauwaenga. Ko ētahi pukapuka e ine ana i ngā tawhiti mai i te pāpāho, e whakaiti ana i te tawhiti katoa, engari ka whakamahia e tēnei tātaitai te tauwaenga.
He aha te whakamahinga o ngā uara tūturu e MAD?
Ko ngā whakarerekētanga i runga ake i te tau tōrunga, ā, ko ērā i raro iho he tōraro, ā, ko te kore tonu te tāpiri, nō reira kāore e whai hua ana to rātau tau tōtika.
He aha te wā e manakohia ai e au te MAD i runga i te whakarerekētanga paerewa?
Ka kōwhiria te MAD ina hiahiatia e koe tētahi inenga whakawhānui he ngāwari ki te whakamārama, he kaha ki ngā tāurunga, ina tino taumaha rānei te tapawhā ki ētahi uara tino nui. E manakohia ana te whakarerekētanga paerewa ina hiahiatia e koe ngā āhuatanga pāngarau e whakanao ana, pēnei i te tuaritanga pūnoa, i ngā whakamātautau rānei i runga i te rerekētanga.
Ka kore pea te rerekētanga tōtika o te tauwaenga?
Ahakoa anake te wā e ōrite ana ia uara ki te waenganui — arā, ina ōrite ngā tau katoa, ā, kāore he horahanga; Kāore anō kia ōrite te MAD ki tētahi tau tōrunga i ngā wā katoa.
