COVID-19 DATA RELIABILITY RANKING OF COUNTRIES WITH GREY RELATIONAL ANALYSIS AND BENFORD’S LAW / Gri İlişkisel Analiz Ve Benford Yasası Yardımıyla Ülkelerin Covid-19 Veri Güvenirliği Sıralaması

Öz

Covid-19 hastalığı, dünya çapında beklenmedik bir hızla yayılan ve pandemi olarak ilan edilen küresel bir hastalıktır. Mart 2022'nin başında dünya çapında 450 milyondan fazla vaka ve 6 milyondan fazla ölüm rapor edilmiştir. Benford yasası, tekrarlayan sayıları kullanan bir veri yapısında veri sahtekârlığı yapılıp yapılmadığını belirlemeye yarayan istatistiksel bir tekniktir. Bu çalışmada, etkin bir veri sahtekârlığı yöntemi olan Benford yasası yardımıyla dünya genelinde 5 milyondan fazla vakaya sahip 18 ülke gri ilişkisel analiz kullanılarak veri sahteciliğine göre sıralanmıştır. Gri ilişkisel analiz yöntemi ve Benford analizi sonuçları yardımıyla 2 yıllık veriler için 18 ülke ayrı ayrı listelenmiştir. Çalışmanın sonuçlarına göre bazı ülkelerin 2020 ile 2021 yılları arasında veri güvenirliğinde değişiklik gösterdiği belirlenmiştir. En güvenilir verilerin Almanya, Fransa ve Hollanda olduğu belirlenmiştir.

COVID-19 DATA RELIABILITY RANKING OF COUNTRIES WITH GREY RELATIONAL ANALYSIS AND BENFORD’S LAW / Gri İlişkisel Analiz Ve Benford Yasası Yardımıyla Ülkelerin Covid-19 Veri Güvenirliği Sıralaması

Abstract

The covid-19 disease has become a pandemic that spreads at an unexpected pace around the world. There are more than 450 million cases and 6 million deaths worldwide at the start of March 2022. Benford's law is a statistical technique that serves to determine whether data fraud has been committed in a data structure that uses repetitive numbers. In this study, 18 countries with more than 5 million cases worldwide were ranked using grey relational analysis with the help of Benford's law, an effective method of data fraud. 18 countries are listed separately for 2 years of data with the help of the grey relational analysis method and Benford’s analysis results. According to the results of the study, it was determined that some countries showed changes in data reliability between 2020 and 2021. It has been determined that the data of Germany, France, and the Netherlands are the most reliable.
