Quiz Description

 In this quiz, we are going to focus on what a statistic is and the questions provided to you by gcequiz.com in this quiz, o level statistics 1, have been set based on the national syllabus for the ordinary level.  

Statistics is a discipline that is studied in Mathematics, Computer science, Economics and so many other subjects. Statistics is concerned with gathering, arranging, examining, clarifying and presenting data. We have set so many quizzes to help you in your studies and in your preparation for the GCSE or GCE O level.

Statistics is the order that worries the assortment, association, examination, understanding, and introduction of information. At the end of the day, it is a numerical control to gather and sum up information.

To test your knowledge on this particular aspect of ordinary level mathematics, you can go ahead and answer the quiz.
