Sažetak
The purpose of this thesis paper is to explore an online dataset about chocolate bar ratings to come up with answers to the questions such as which companies produce the best chocolate bar, which countries grow the best cocoa beans, and which ingredients does the best chocolate bar contain. These questions are answered using ANOVA. Additionally, a linear regression model is created which predicts the ratings of chocolate bars based on the company that produces it, specific bean origin or bar name, first taste, second taste, and the percentage of cocoa in the chocolate bar. Furthermore, a sentiment analysis is performed on tweets containing #chocolate in order to see whether the emotions of people are more positive or negative regarding the topic of chocolate.
