Abstract: In the past decades, the development of computer science and internet techniques has enabled researchers to collect, store, and analyze data at an unparalleled speed, with which we have entered the era of big data. Big data have unique characteristics (volume, variety, velocity, and veracity), which bring opportunities as well as challenges to statistics and statisticians. In this article, we examine the history of statistical methodological development and analyze the characteristics of statistical development, based on which we propose the positioning of statistics in the big data era and discuss the interconnections and interactions between statistics and computer science/internet technologies. At the end, we clarify a few misunderstandings in big data analysis.

Key words: Big Data, Computer Science, Causality, Sampling, Data Quality
