Standart Sapma \u0130\u015flevinin Temelleri<\/h2>\n

Hem MS Excel hem de Google E-Tablolar’da kullan\u0131lan STDEV<\/strong> (T\u00fcrk\u00e7ede STDSAPMA<\/strong>) i\u015flevi, belirli bir veri k\u00fcmesinin de\u011ferlerinin ortalamadan ne kadar yay\u0131ld\u0131\u011f\u0131n\u0131 \u00f6l\u00e7mek i\u00e7in kullan\u0131l\u0131r. Bu i\u015flev, finans, m\u00fchendislik, istatistiksel analizler ve daha bir\u00e7ok alanda verilerin varian\u0131n\u0131 anlamak i\u00e7in kritik bir rol oynar. <\/p>\n

\u0130\u015flevin S\u00f6zdizimi ve \u00d6rnekler<\/h2>\n

STDEV<\/strong> i\u015flevinin genel s\u00f6zdizimi a\u015fa\u011f\u0131daki \u015fekildedir: <\/p>\n

  STDEV(number1, [number2], ...) <\/code> <\/pre>\n
 Burada, number1, number2, ...<\/code> i\u015flevin hesaplanmas\u0131nda kullan\u0131lacak say\u0131lard\u0131r. Say\u0131lar do\u011frudan, h\u00fccre referanslar\u0131 veya aral\u0131klar \u015feklinde olabilir. <\/p>\n
 \u00d6rnek olarak, bir s\u0131n\u0131ftaki \u00f6\u011frencilerin matematik s\u0131nav\u0131ndaki puanlar\u0131n\u0131n standart sapmas\u0131n\u0131 hesaplamak istedi\u011fimizi d\u00fc\u015f\u00fcnelim. \u00d6\u011frencilerin ald\u0131\u011f\u0131 puanlar s\u0131ras\u0131yla 70, 85, 90, 95 ve 100 olsun. Excel veya Google E-Tablolar’da bu veriyi kullanarak hesaplama yap\u0131labilir: <\/p>\n
  =STDEV(70, 85, 90, 95, 100) <\/code> <\/pre>\n
 Bu form\u00fcl, belirtilen puanlar\u0131n standart sapmas\u0131n\u0131 hesaplar ve sonucu verir. <\/p>\n
\u0130\u015flevin Uygulama Alanlar\u0131<\/h2>\n
    \n
  • Finansal Risk De\u011ferlendirmesi:<\/strong> Yat\u0131r\u0131m portf\u00f6ylerinin volatilitesini ve risk seviyesini de\u011ferlendirmek i\u00e7in kullan\u0131labilir. Daha y\u00fcksek standart sapma, y\u00fcksek risk ve volatiliteyi g\u00f6sterir.<\/li>\n
  • Kalite Kontrol:<\/strong> \u00dcretim s\u00fcre\u00e7lerinde, \u00fcr\u00fcnlerin belirli bir kalite standard\u0131 \u00e7er\u00e7evesinde \u00fcretildi\u011finden emin olmak i\u00e7in standart sapma hesaplamalar\u0131 yap\u0131l\u0131r. \u00dcretim s\u00fcre\u00e7lerinin sabitli\u011fi ve \u00f6ng\u00f6r\u00fclebilirli\u011fi hakk\u0131nda bilgi sa\u011flar.<\/li>\n<\/ul>\n
    Detayl\u0131 Kullan\u0131m Senaryosu ve \u00c7\u00f6z\u00fcmlemeler<\/h2>\n
     1. Senaryo: Portf\u00f6y Y\u00f6netimi<\/strong>
     Bir yat\u0131r\u0131mc\u0131, farkl\u0131 hisse senetlerinden olu\u015fan bir portf\u00f6ye sahip oldu\u011funu varsayal\u0131m. Hisse senetlerinin ge\u00e7mi\u015f getirileri s\u0131ras\u0131yla %5, %10, %15, ve %20 olsun. Yat\u0131r\u0131mc\u0131, portf\u00f6y\u00fcn\u00fcn risk de\u011ferini \u00f6l\u00e7mek istiyor. <\/p>\n
      =STDEV(5%, 10%, 15%, 20%) <\/code> <\/pre>\n
     Bu \u00f6rnek, hisse senetlerinin getiri oranlar\u0131n\u0131n standart sapmas\u0131n\u0131 hesaplayarak, yat\u0131r\u0131mc\u0131ya risk hakk\u0131nda bilgi verir. <\/p>\n
     2. Senaryo: \u00dcretim Kalite Kontrol\u00fc<\/strong>
     Bir fabrika, belirli bir par\u00e7an\u0131n \u00fcretim toleranslar\u0131n\u0131 \u00f6l\u00e7mektedir. \u00d6l\u00e7\u00fcm sonu\u00e7lar\u0131 milimetre cinsinden 15.0, 15.3, 15.8, 14.9 ve 15.2 olsun. \u015eirket, \u00fcretim s\u00fcrecinin kalitesini analiz etmek istiyor. <\/p>\n
      =STDEV(15.0, 15.3, 15.8, 14.9, 15.2) <\/code> <\/pre>\n
     Hesaplanan standart sapma, \u00fcretim s\u00fcrecinin tutarl\u0131l\u0131\u011f\u0131n\u0131 ve toleranslar\u0131na uygunlu\u011funu g\u00f6sterir, b\u00f6ylece s\u00fcre\u00e7 iyile\u015ftirmeleri i\u00e7in bir temel sa\u011flar. <\/p>\n","protected":false},"excerpt":{"rendered":"
