Ngokuningiliziwe kwe-PPM ye-Arbitron yokulinganisa ukulalela kwe-Radio Station
I-Portable People Meter - PPM okwesikhashana - iyisetshenziswa sogesi esetshenziswa yi-Arbitron, inkampani yokucwaninga imithombo yezindaba, esetshenziselwa ukwakha imikhuba yokulalela esikhundleni seziteshi zomsakazo e-United States.
Isebenza kanjani?
Ngokusho kwewebhusayithi ka-Arbitron:
"I-Arbitron Portable People Meter technology ilandelela ukuchayeka kwabathengi kumaphephandaba nakwazokuzijabulisa, kufaka phakathi ithelevishini, i-cable kanye nethelevishini ye-satellites; umhlaba jikelele, i-satellites kanye ne-inthanethi yomsakazo kanye nokukhangisa kwe-cinema nezinhlobo eziningi zemidiya ye-digital esekelwe endaweni.
Izimpawu zokusakazwa zifakwe ikhodi ngamasignali angenakuzwakalisa njengoba zomoya noma zisakaza bukhoma. Lezi amakhodi zitholwa yi-software engalandwa kudivayisi yeselula noma kwesicelo sekhompyutha. Isofthiwe ye-PPM ifakwe inzwa yomsindo, isici sokulawula ikhwalithi ehambisana ne-brevent esiyingqayizivele ohlelweni, okuvumela i-Arbitron ukuqinisekisa ukulandelwa kwabahlanganyeli be-PPM abacwaningi nsuku zonke. "
Abakwa-Arbitron othintana nabo (ababizwa ngokuthi i-panelists) ezimakethe lapho kuhlolwa khona abalaleli. Inkampani yakha isampula engahleliwe ngokuhlanganisa ama-panelists ekugcineni abe "iphaneli" - iqembu labantu abavumelene ukuthwala i-PPM. (Inqubo ye-diary yase-Arbitron yokuqala, "iphaneli" ibizwa ngokuthi "isampula".)
Izikhathi zokuhlola ze-PPM zihlala izinsuku ezingu-28.
Ngemuva kokuba idatha ihlanganiswe, i-Arbitron ibika izilinganiso ezintathu zezilaleli eziyisisekelo:
Abantu: inani elilinganisiwe labantu abalalelayo
Isilinganiso: iphesenti yendawo yokuhlola eyenza abantu belalela isiteshi
Yabelana: iphesenti yazo zonke ukulalela umsakazo okwenzeka ngesiteshi esithile.
Isizukulwane esisha se-PPM technology yi-PPM 360. I-Arbitron ithi:
Ukuklama kwedivayisi entsha kufana neselula elula futhi i-sleeker futhi encane kunamitha wamanje. Ukufakwa kobuchwepheshe obungenazintambo ngamangqamuzana kumamitha kuqeda isidingo sokwenza isiteshi se-docking ekhaya kanye nehabhu lokuxhumana, ukudala isipiliyoni esithuthukisiwe, esithuthukisiwe se-panelist.
