The Department of Accounting and Statistics, founded in 1955, was divided into the Accounting Division and the Statistics Division in 1958. In August 1974, the two divisions became independent departments: the Department of Accountancy and the Department of Statistics. In the same year, the evening program of the Department was established. It started the master program in August 1991. In 1998, the Department began to offer the Ph.D. degree. In addition, to coincide with the era of big data, the Department of Statistics applied for the establishment of "Institute of Data Science".
