[Part A: Module II - Hypothesis Testing and Statistical Inference Metacritic and One Night In Miami] Metacritic is a website that aggregates reviews of music, games, and movies. For each product, a numerical score is obtained from each review and the website posts the average score as well as individual reviews. The website is somewhat similar to Rotten Tomatoes, but Metacritic uses a different method of scoring that converts each review into score in 100-point scale. In addition to using the reviewer's quantitative ratings, Metacritic manually assesses the tone of the review before scoring. Historical data shows that these converted scores are normally distributed. One of the movies that the Metacritic rated was One Night In Miami. The first review came out on Sep 10, 2020 (Jamie Graham from Total Film) and other reviews started to trickle in before the movie was released on December 25, 2020. The data in the "One Night In Miami" sheet of "Part A - Data Sets for Assessment Assignment.xlsx" contains a sample of the media outlets, reviewers, scores and review dates for all reviews that Metacritic collected until the release date.
