Microsoft Excel ve Google Sheets, bilgisayar destekli hesaplamalar ve veri analizleri i\u00e7in geni\u015f fonksiyon setleri sunan vazge\u00e7ilmez ara\u00e7lard\u0131r. Bu platformlar, istatistiksel analizlerden finansal modellemeye kadar bir\u00e7ok farkl\u0131 alanda etkin bir \u015fekilde kullan\u0131lmaktad\u0131r. \u00d6zellikle istatistiksel fonksiyonlar, veri analizi s\u00fcre\u00e7lerinde kritik bir rol oynamaktad\u0131r. Bu metinde, istatistiksel fonksiyonlardan biri olan ve standart normal da\u011f\u0131l\u0131m\u0131n yo\u011funluk fonksiyonunu hesaplamak i\u00e7in kullan\u0131lan PHI fonksiyonunun nas\u0131l kullan\u0131laca\u011f\u0131n\u0131 inceleyece\u011fiz.<\/p>\n

Syntax ve Kullan\u0131m\u0131<\/h2>\n

PHI fonksiyonunun syntax’\u0131 son derece basittir. Bu fonksiyon, belirli bir de\u011fer i\u00e7in standart normal da\u011f\u0131l\u0131m\u0131n yo\u011funluk de\u011ferini hesaplar.<\/p>\n

=PHI(x)<\/code><\/pre>\n
    \n
  • x:<\/b> Z-skoru veya standart normal da\u011f\u0131l\u0131mdaki bir de\u011fer.<\/li>\n<\/ul>\n
    \u00d6rnek:<\/b> E\u011fer x = 1 i\u00e7in PHI fonksiyonunu kullanmak istiyorsan\u0131z,<\/p>\n
    =PHI(1)<\/code><\/pre>\n
    form\u00fcl\u00fcn\u00fc yazarak x = 1 i\u00e7in standart normal da\u011f\u0131l\u0131m yo\u011funlu\u011funun de\u011ferini elde edebilirsiniz.<\/p>\n
    Pratik Uygulamalar<\/h2>\n
    Uygulama 1: Pazar Ara\u015ft\u0131rmas\u0131<\/h2>\n
    Bir \u015firket, \u00fcr\u00fcnleri ile ilgili m\u00fc\u015fteri memnuniyetini de\u011ferlendirirken, memnuniyet skorlar\u0131n\u0131n normal bir da\u011f\u0131l\u0131m izledi\u011fini varsaymaktad\u0131r. M\u00fc\u015fteri memnuniyet skorlar\u0131, ortalama 5 ve standart sapma 1.5 olan bir da\u011f\u0131l\u0131m g\u00f6stermektedir. Bu durumda, m\u00fc\u015fteri memnuniyetinin \u00f6l\u00e7\u00fclen belirli bir de\u011feri i\u00e7in yo\u011funluk de\u011ferini hesaplamak amac\u0131yla PHI fonksiyonu kullan\u0131labilir.<\/p>\n
    X de\u011ferini hesaplama: Z = (X - ortalama) \/ standart sapma Z = (5 - 5) \/ 1.5 = 0 PHI fonksiyonunun de\u011feri: =PHI(0)<\/code><\/pre>\n
    Burada elde edilen sonu\u00e7, m\u00fc\u015fteri memnuniyet skorlar\u0131n\u0131n yo\u011funlu\u011funun en y\u00fcksek oldu\u011fu noktay\u0131 g\u00f6sterir.<\/p>\n
    Uygulama 2: Mali Karar Destek<\/h2>\n
    Bir finans analisti, belirli bir yat\u0131r\u0131m \u00fcr\u00fcn\u00fcn\u00fcn getirisinin normal da\u011f\u0131l\u0131mda oldu\u011funu ve ortalaman\u0131n %8, standart sapman\u0131n ise %2 oldu\u011funu belirlemi\u015ftir. Analist, %10 getiri oran\u0131n\u0131n yo\u011funluk de\u011ferini hesaplamak istemektedir.<\/p>\n
    X de\u011ferini hesaplama: Z = (%10 - %8) \/ %2 Z = 1 PHI fonksiyonunun de\u011feri: =PHI(1)<\/code><\/pre>\n
    Hesaplanan Z de\u011feri 1 oldu\u011funda, bu de\u011fer PHI fonksiyonu ile standart normal da\u011f\u0131l\u0131m yo\u011funlu\u011fu hesaplamalar\u0131nda kullan\u0131l\u0131r. Bu, yat\u0131r\u0131m\u0131n getiri da\u011f\u0131l\u0131m\u0131n\u0131n karakteristi\u011fini analistlere sunar.<\/p>\n
