Statistics Part 2 Quiz

Statistics Part 2 Quiz is built for those who enjoy spotting patterns in the most ordinary of things. In the early 1900s, Guinness Brewery hired a statistician named William Sealy Gosset to improve quality control. Due to company policy, he published his breakthrough work under the name “Student,” giving birth to the famous Student’s t-test. That’s one of the many moments where statistics changed business forever. This quiz invites you to explore core ideas like the median vs mean debate and understand concepts behind the interquartile range statistics. With engaging statistics MCQ questions and a practical central tendency quiz, this set encourages you to think like a statistician. You’ll also get a better grasp of which central tendency is at the 50th percentile.
