Genel Bak\u0131\u015f: BO\u015eLUKSAY Fonksiyonu<\/h2>\n

Microsoft Excel ve Google Sheets’de kullan\u0131lan BO\u015eLUKSAY<\/code> (\u0130ngilizce’de COUNTBLANK<\/code>) fonksiyonu, belirlenen bir h\u00fccre aral\u0131\u011f\u0131ndaki bo\u015f h\u00fccre say\u0131s\u0131n\u0131 hesaplamak i\u00e7in kullan\u0131l\u0131r. Bu fonksiyon, veri eksikliklerini belirleme ve analiz i\u015flemlerinde son derece faydal\u0131d\u0131r.<\/p>\n

Fonksiyon S\u00f6zdizimi ve \u00d6rnek Kullan\u0131m<\/h2>\n

BO\u015eLUKSAY<\/code> fonksiyonunun s\u00f6zdizimi a\u015fa\u011f\u0131daki gibidir:<\/p>\n

=BO\u015eLUKSAY(aral\u0131k)<\/code><\/pre>\n
Burada aral\u0131k<\/code>, fonksiyonun \u00fczerinde \u00e7al\u0131\u015faca\u011f\u0131 h\u00fccre blo\u011funu belirtir.<\/p>\n
\u00d6rnek kullan\u0131m:<\/p>\n
=BO\u015eLUKSAY(A1:A10)<\/code><\/pre>\n
Bu form\u00fcl, A1’den A10’a kadar olan h\u00fccrelerde bulunan bo\u015f h\u00fccrelerin say\u0131s\u0131n\u0131 hesaplar.<\/p>\n
Pratik Uygulama Senaryolar\u0131<\/h2>\n
Senaryo 1: \u00d6\u011frenci Devams\u0131zl\u0131k Takibi<\/h2>\n
Bir \u00f6\u011fretmen, \u00f6\u011frencilerin devams\u0131zl\u0131k g\u00fcnlerini Excel \u00fczerinde bir tablo kullanarak kaydetmektedir. Her bir \u00f6\u011frenci i\u00e7in ayr\u0131 h\u00fccrelerde devams\u0131zl\u0131k bilgisi tutulmaktad\u0131r. \u00d6\u011fretmen, s\u0131n\u0131f\u0131n genel devams\u0131zl\u0131k g\u00fcnlerini \u00f6\u011frenmek istiyor:<\/p>\n
A1: \u00d6\u011frenci 1 A2: \u00d6\u011frenci 2 A3: \u00d6\u011frenci 3 ... A10: \u00d6\u011frenci 10 B1: 2 B2: B3: 3 ... B10:<\/code><\/pre>\n
Devams\u0131zl\u0131k yapmayan \u00f6\u011frencileri belirlemek i\u00e7in B s\u00fctunundaki bo\u015f h\u00fccreleri sayabiliriz:<\/p>\n
=BO\u015eLUKSAY(B1:B10)<\/code><\/pre>\n
Bu komut, B s\u00fctunundaki bo\u015f h\u00fccre say\u0131s\u0131n\u0131, yani rapor edilmemi\u015f devams\u0131zl\u0131k g\u00fcnlerini hesaplar.<\/p>\n
Senaryo 2: Anket Verilerinde Eksik Yan\u0131tlar\u0131n Tespiti<\/h2>\n
Bir ara\u015ft\u0131rmac\u0131, anket sonu\u00e7lar\u0131n\u0131 analiz ederken, her soruya ka\u00e7 ki\u015finin yan\u0131t vermedi\u011fini tespit etmek istiyor:<\/p>\n
C1: Soru 1 C2: Soru 2 C3: Soru 3 D1: Evet D2: D3: Hay\u0131r E1: Hay\u0131r E2: Evet E3:<\/code><\/pre>\n
Her bir soru i\u00e7in eksik yan\u0131tlar\u0131 hesaplamak amac\u0131yla a\u015fa\u011f\u0131daki form\u00fcller kullan\u0131labilir:<\/p>\n
=BO\u015eLUKSAY(D1:E1) - \u0130lk soruya yan\u0131t vermeyen ki\u015fi say\u0131s\u0131n\u0131 hesaplar. =BO\u015eLUKSAY(D2:E2) - \u0130kinci soruya yan\u0131t vermeyen ki\u015fi say\u0131s\u0131n\u0131 hesaplar. =BO\u015eLUKSAY(D3:E3) - \u00dc\u00e7\u00fcnc\u00fc soruya yan\u0131t vermeyen ki\u015fi say\u0131s\u0131n\u0131 hesaplar.<\/code><\/pre>\n
Bu form\u00fcller, her soru i\u00e7in bo\u015f yan\u0131t say\u0131s\u0131n\u0131 belirleyerek eksik verilere dair h\u0131zl\u0131 bir genel de\u011ferlendirme sunar.<\/p>\n","protected":false},"excerpt":{"rendered":"
