Summary/Abstract: Today businesses and organizations generate and gather data at an increasing pace. The term big data is a catch-phrase, meaning a massive amount of structured, semi-structured and unstructured data. Despite the fact that big data is used in advanced analytics to solve all sorts of problems and make informed decisions, they are extremely difficult to manage, process, and analyze using traditional data-processing tools. This research aims to present the opportunities and challenges of big data. For instance, the huge sample sizes may detect differences that are quite small and trivial. This problem is associated with the relationships among sample size, pvalue, and effect size. To report an effect size is a critical step for scientific studies and may show significant differences according to research types. Despite the challenges, big data presents a great opportunity to gain knowledge of all fields of our life.
